Friction materials are a type of material employed to produce friction in situations where slow or decreased movement is needed. The definition of friction is the resistance to relative motion that opposes an object’s direction of movement. Friction is produced when a solid object comes into contact with a deviating surface. Friction can be used anywhere from simply slowing down or stopping an object to accelerating it to a certain speed. Applications include clutch and brake systems, operating systems, automotive equipment, gear tooth systems, and industrial machinery that all need to be able to stop or slow down their processes. Components such as friction pads and linings and disc brake pads are made from friction materials. Industries that make frequent use of these products include construction, automotive, forestry, oil and gas, and mining.

Braking Systems

Friction materials are used in braking systems to slow down wheels or bring them to a stop, as well as preventing movement altogether for other components. Pressing a brake activates a system where a friction material is placed against a moving disc, thus slowing down the connecting wheels.

Materials

Since heat energy is a byproduct of the process of creating friction, manufacturers typically use materials that are resistant to heat to make friction materials. The most popular choice for friction materials used to be fibers made from asbestos. However, due to the increase of health concerns associated with exposure to asbestos, ceramic has become a popular material to use as an alternative. Ceramic is highly durable and resistant to heat and is thus used in high friction environments. Friction materials need to be capable of enduring high amounts of physical stress, since the wearing down of material unavoidably produces friction. In addition, manufacturers made products such as semi-metallic brake materials using brass, copper, and steel wool bonded by resin. These elements are similar to ceramic in terms of durability.

Considerations and Customization

The type of material used depends significantly on the type of friction that is needed. Types of friction include static, kinetic, and rolling friction.
  • Static friction:
Occurs when two solid objects do not move relative to each other, and movement is prevented altogether. An important thing to consider when implementing this type of friction is the slope of the surface.
  • Kinetic friction:
This happens when two objects move relative to one another. One surface may be moving along a stationary object, or both surfaces may be in motion.
  • Rolling friction:
This type involves the use of wheels or balls. During rolling friction, a rough material catches a wheel or ball, preventing it from slipping or sliding. For example, when a car tire spins on ice or snow, friction prevents it from catching on the ground and allows it to keep rotating. To determine the best friction materials for the job, manufacturers also think about how quickly the friction needs to stop the object or system (the higher the friction, the faster the object can be stopped), how frequently the friction material will be used, budget, required chemical resistance, required wear resistance, permissible heat generation, required energy absorption and coefficient of friction. In order to provide additional friction and therefore increase their efficiency, friction materials are textured or have a rough surface. Manufacturers utilize smoother surfaces to transport materials more efficiently. Also, manufacturers can add rubber to enhance the braking system’s ability to produce surface friction. However, the more texture is added to a surface, the greater the amount of energy required to move over it.

You would think that all a vehicle tech would need to do is plug your car into the diagnostic scanner and they would know exactly what the problem is right? No, just simply plugging in an automotive diagnostic scanner into your car or truck and reading codes is not all there is to accurately diagnosing a engine problem. We feel you shouldn’t be charged for this procedure either! Other courses of action to find a problem or failure which require test equipment and time can be chargeable services though. The more knowledgeable the tech is and the better equipped the shop is for diagnosing, the less it will cost you.  Misdiagnosis and just randomly replacing parts will cost big time.  The automatic transmission specialist is the most highly skilled technologically.  His knowledge and skill are above every other tech’s.  His diagnostic tools are better because the automatic transmission demands it, as it is the most complicated part of your vehicle.  The transmission relies on many other systems so the tech must be able to evaluate these systems as well.  A difficult drive-ability or drive train problem will, in most cases, be solved by a transmission tech. Leaks Your vehicle whether new or antique uses at least 8 types of fluid.  Engine oil, transmission fluid, brake fluid, power steering fluid, coolant, gear oil, gasoline and window washing fluid.  Every one of these systems has hoses, gaskets, seals and warped metal surfaces.  All of these will leak fluids eventually. Noise Noises can drive the car owner crazy with worry.  Noises are probably the most misdiagnosed problems.  More labour hours and money have been wasted hunting down a noise.  The most common reason is that squeaks and rattles telescope sound.  The problem may be located in one spot, the resulting sound may appear in another.  Only a savvy tech can solve this problem with the least amount of time and expense. Electrical These failures are now more prevalent because most everything on vehicles is either controlled by or operating on current.  The car’s computer and a smart tech with an up-to-date scanner will be able to find the problem. Mechanical Failure Most mechanical diagnoses require dis-assembly to determine the extent of damage.  Internal failures in engines, transmissions, brakes, power door windows, steering and suspension can be expensive to repair or replace.  A precise diagnosis is even more critical here, to prevent extra labour time.   When it’s time for to diagnose your engine problem or transmission problem, trust the experts at Brakecore Supply. the Company has developed into one of South Africa’s premier suppliers to the Agriculture, Transport, Industrial, Marine, Underground Mining, Opencast Mining.

The Sealed Integrated Braking System (SIBS®) is a distinctive world-class product leading the way in brake equipment. SIBS® is a fully enclosed, single-rotor, high speed ‘wet’ disc brake that has better dependability than standard brakes and operates in the severest of conditions with virtually no need for maintenance or overhauling. Developed through widespread research and patented globally, SIBS® brakes provide unequaled dependability in any situation. SIBS® are specially designed to protect you, your machinery and our environment. SIBS® brakes increase your output by removing periods of extended downtime while the brakes are being serviced. As SIBS® brakes are fully enclosed, they produce no dangerous emissions and are the most environmentally friendly brakes on the market. SIBS® brakes are currently available for many on-road/off-road light commercial vehicles. Highly flexible, SIBS® can be fitted (or retrofitted) to any braked application, large or small, automotive or industrial. The manufacturing of SIBS® is simple: The brake caliper, providing the braking force, is extended to enclose the disc. This makes up the casing. The housing is divided around the disc into inner and outer portions. The inner housing is attached to the axle end. The pads, disc, and hub are fitted; and the outer housing is fitted to complete the assemblage and enclose the brake components. At this point, SIBS® cooling fluid is added into the casing. SIBS® cooling fluid is a specifically selected oil which offers a path to conduct the heat from the brake disc to the housing. This allows the heat to then be rejected from the housing to the surrounding air, guiding the working temperature of the system.   Brakecore Visit us today at Brakecore and let our industry specialists use their expertise to advise you on this fail-safe system.
It is undeniable that the more one knows about the functions of their vehicle, the better the choices will be when new cars acquired. Furthermore, there is a better understanding of what preventive maintenance should be done and when it ought to be scheduled. Brakes are the most vital safety feature of any vehicle. There are two kinds: disc brakes and drum brakes. Functions of drum & disc brakes A drum brake is a small round drum that has a set of shoes within it. The drum brake will rotate together with the wheel and when the brake pedal is applied, the shoes are pressed up against the sides of the drum and the wheel is slowed down. A disc brake consists of a disc shaped metal rotor that rotates within a wheel. When pressure is applied to the brake pedal, a calliper will squeeze the brake pads against the disc. This will slow the wheel down as more pressure is applied to the brake pedal, bringing the car to a stop. Which brake to choose? There is a qualitative distinction between the two and some of it revolves around friction. The disc brake dispels the heat more effectively. Brake fade occurs when the brakes begin to lose their efficacy and this can happen on steep downhills for the drum brake design. It takes longer for the disc brake achieve brake fade, and these perform better on steep descends. The drum brake has the possibility of accumulating water within during rain or driving through puddles. That can lead to the drum brakes not performing as well in wetter conditions. It is possible that your car may have disc brakes in the front end with drum brakes dealing with the rear tires. The reason is pure economics. Because a car weight is going to shift with braking, over two thirds of the braking effort occurs in the front of the car. There is not quite the need to have disc brakes, which are more expensive than drum brakes, on all four wheels. The maintenance of a drum brake is also cheaper. The brake drum has an all-in-one design that is very easy to replace when repair work is needed. In fact, the brake shoes can be replaced in less than ten minutes when the drum has been taken off. This means that both parts and labour costs are dramatically reduced when a drum brake is on the car. The drum brake also gets the job done, and both types of brakes will bring the car to a stop. What is important to keep in mind is that either brake system is going to bring the car to a stop; the disc brake just does it more efficiently. The cost consideration is something that a car owner may want to think about. Understanding that most of the braking work will be at the front of the car, a model of car that has front disc brakes and rear drum brakes conceivably has the best of all possible worlds. The drum brakes in behind are much easier to replace if necessary. The owner can concentrate maintenance efforts on the front brakes and not worry too much about the rear ones. Overall safety and efficiency may be something that the car owner is concerned about, particularly in looking at a family car. In these situations, the disc brake system on all four corners may be the best because it is the safest. It just is up to consumer which brake system, either a four disc brakes or a combination of the two types, is going to be what fits the need.   Since Brakecore Supply’s inception in 1983, our mission is to continuously strive to provide our customers with the best possible quality and service at acceptable prices, and to keep on pursuing the possibilities of bettering these goals.

Fail-safe brakes (also called Sealed Integrated Braking Systems) are an integral component for vehicles and machines in many industries. They provide heavy-duty stopping power, greater integrity and safer operation for your vehicles and fleet, and is one of the only products out there that does this with turnkey functionality. But what are fail-safe brakes? How do they work and why should your company’s fleet be fitted with them as soon as possible? Find out more here… What are Fail-Safe Brakes? In fail-safe brakes, multiple brake disks are hydraulically released whenever the brakes are applied, while the entire system is integrated with the drive train of the vehicle. This means that even in the event that the brakes should fail, one of the multiple brake pads will still allow the vehicle to stop, and to be held in position. This points to a few obvious benefits with regards to fleet and personnel safety; but let’s have a look at some of the other top advantages of using fail-safe brakes. They Last Longer than Any Other Solution Fail safe brakes and their simplistic, multi-pad design ensure that the component enjoys a longer lifespan than other stopping solutions. In fact, fail-safe brakes have been known to outlive the vehicles that they are fitted to, which means that aside from lasting longer, they can also be reused on other vehicles if they are looked after properly. They Reduce Maintenance Costs Another advantage to the lengthened lifespan of fail-safe brakes is that you will likely end up spending far less on maintenance, repairs and replacements in the long run; since these components have been designed to work on rough and rugged terrain, for incredibly long periods of time. They are Very Tough Fail safe brakes have a holding capacity of over 2.6 times that of other braking solutions making it very well suited to extremely tough environments. This coupled with their re-usability and durability, make them a solution that provides excellent value for money. Easy to Work With The simplistic design of fail-safe brake systems means that any experienced technician with the right tools will be able to work on them. This is true for instances where they need to be installed, adjusted, maintained, removed or repaired.

Heavy earthmoving equipment is a construction business and road crew labour essential. These vehicles make it possible to carry out large-scale jobs in a greatly reduced time-frame. There are 4 main earthmoving vehicles that are most frequently used on construction and excavation sites. Though generally used by professionals in construction and road maintenance, some of these vehicles are available in smaller forms for nonprofessional application. Backhoe Loaders A backhoe loader is basically a tractor-like vehicle with an adjustable, bucket-shaped shovel on the front of the vehicle, and a smaller, adjustable bucket in the back of the vehicle for digging. The first backhoe loaders were manufactured in the 1950s, with the main part of the vehicle being modeled on the common farm tractor. The driver’s seat in a backhoe loader can swivel to face forward or backward to make switching from digging to shoveling easier. Compared to other earthmoving equipment, the backhoe loader is smaller and more compact, making it fitting for urban or suburban construction projects where work space may be very limited. Excavators An excavator is an example of what is termed heavy construction equipment. They are large and weighty vehicles which move on tank treads rather than tires. There is one long bucket arm on a traditional excavator, and the buckets on an excavator are frequently quite big and wide. The arm is attached to a pivoting cab, in which the operator sits. This cab can rotate a full 360 degrees, giving the operator of the excavator the benefit of being able to park the large vehicle in one spot and work the surrounding area from one convenient point. Excavators are mainly used for digging substantial amounts of dirt quickly, but are sometimes also used for heavy lifting and large pipe placement. Bulldozers As with the backhoe loader, the main vehicle component of the bulldozer was modeled on the farm tractor, while the tank treads a bulldozer uses for movement are reminiscent of the excavator. It is also considered to be heavy construction equipment, given its size, weight and the volume of earth it can move. Bulldozers are equipped with a wide, flat blade in the front. The blade is attached to two hydraulic arms that do not protrude very far from the front of the vehicle, unlike the hydraulic arms of the backhoe loader and excavator. Bulldozers are mainly used for pushing substantial piles of earth, and for grading land to make it more level. Variations on the flat front blade enable some bulldozer models to gather earth as well as move it, or to move boulders and rock piles, specifically. Dump Trucks Industrial dump trucks are another example of heavy construction equipment, and are used to transport large amounts of earth, or to transport materials like gravel to a construction site. A dump truck has no attachments, but does possess a hydraulically operated bed. When the contents within the bed are to be deposited, the end of the bed toward the front of the vehicle rises up on hydraulic pistons, causing the contents of the bed to slide off and to the ground. Traditionally, the dump truck was a large industrial piece of equipment owned only by construction companies, as well as town, city and state road crews. Recently, smaller dump trucks have been designed for the average person, which consist of a hydraulic bed mounted on a standard pickup truck.   Much like most industrial mechnisms, earthmoving equipment maintenance is paramount for all applications. Since 1983, Brakecore Supply has developed into one of South Africa’s premier suppliers to the Agriculture, Transport, Industrial, Marine, Underground Mining, Opencast Mining.
