Brake Linings

Brake linings, also called brake pads, are the consumable surfaces in brake systems, such as drum brakes and disc brakes used in vehicles, and are considered a critical component, as they are the material which comes in contact with the rotors in order to slow them down without wearing them out too quickly.

They are curved thin strips composed of a relatively soft but tough and heat-resistant material like asbestos (it used to be the element most commonly used for brake linings, but the dust created by asbestos is harmful when inhaled), minerals, fine wire, etc. with a high and ideally identical coefficients of dynamic and static friction. These linings are riveted or bonded using high-temperature adhesives to a solid metal backing such as a brake band or shoe to create the friction necessary for braking, while protecting the rotor from coming into direct contact with the metal backing. Braking linings are used in the braking systems in machines, vehicles, appliances and elevators and thus can range from large heavy duty materials to lighter, softer linings.

Featured Fact

"Linings prevent them from wearing out quickly and needing frequent replacing".

Linings prevent them from wearing out quickly and needing frequent replacing, however, linings made from harder materials can cause accelerated wear and tear on the rotors or drums, and therefore it is important to check the quality and the suitability of the material with relation to the specifics of the system.

The material used for brake lining purposes usually has a high coefficient of friction and as it comes in contact with the rotors, creates enough friction allowing vehicles to slow them down relatively quickly. The kinetic energy of the braking process is turned into heat energy. Brake linings, like brake bands and brake blocks, need to be made from more durable materials which are able to endure high levels of heat and pressure.

Brake linings will need to be replaced periodically as the material will inevitably be affected by wear and tear over time. Often the brakes will squeak or become less smooth as the lining wears out, this is important to pay attention to as worn out brake linings can cause greater, and more expensive, engine damage. In systems with multiple brake linings, it is important to replace or repair the corresponding linings at the same time. This is necessary to help achieve even and consistent braking within the system.

Our liners have a long life and assures you a smooth driving experience. They are ideal for vehicles with heavy use requirements.

Rivets

A rivet is a permanent mechanical fastener. Before being installed, a rivet consists of a smooth cylindrical shaft with a head on one end. The end opposite to the head is called the tail. On installation, the rivet is placed in a punched or drilled hole, and the tail is upset, or bucked (i.e., deformed), so that it expands to about 1.5 times the original shaft diameter, holding the rivet in place. In other words, the pounding or pulling creates a new “head” on the other end by smashing the “tail” material flatter, resulting in a rivet that is roughly a dumbbell shape. To distinguish between the two ends of the rivet, the original head is called the factory head and the deformed end is called the shop head or buck-tail.

Brake lining rivets are used to secure brake shoe linings on cars, trucks, and other vehicles. They have flat, chamfered, countersunk heads to provide as smooth a surface as possible once installed. They are a heavy duty alternative to bonding in high load applications such-as truck brakes so that the lining maintains its position relative to the brake share during useful life of the lining. Another benefit of rivets versus bonding alternatives is that the brake shoe may be rebuilt by removing the rivets/sacrificial friction materials and replacing/re-riveting.

With our extensive selection of brake lining and rivets, we’re sure to have the right model for your needs. We offer these rivets in different body diameters, lengths, material options, different head diameters, and different head thicknesses.
