The concept of brake pads or disc brakes as an alternative to drum brakes had been around at least as early as a patent by F. W. Lanchester in 1902. [2] However, due to high cost and inefficiencies compared to drum brakes they were not commonly implemented until after World War II. [3]
Drum brake (upper right) with the drum removed (lower left, inside facing up), on the front of a Ford Falcon Sprint A rear drum brake on a Kawasaki W800 motorcycle. A drum brake is a brake that uses friction caused by a set of shoes or pads that press outward against a rotating bowl-shaped part called a brake drum.
However, air brakes can be made much more effective than vacuum brakes for a given size of brake cylinder. An air brake compressor is usually capable of generating a pressure of 90 psi (620 kPa; 6.2 bar) vs only 15 psi (100 kPa; 1.0 bar) for vacuum. With a vacuum system, the maximum pressure differential is atmospheric pressure (14.7 psi or 101 ...
The brake lining is that part of the brake pad which actually contacts the metal brake disc (rotor) when the brake is engaged. Using a typical bicycle brake as an example, the backing would be the metal shell which provides mechanical support, and the lining would be the rubbery portion which contacts the rims when the brakes are applied.
Generally speaking, a tractor trailer requires more brakes than a typical vehicle, so making the brakes as simple and as cost effective as possible is very important. [citation needed] S-cams are very efficient at keeping brakes maintained because as the brake pad wears, the S-cam rotates more and causes the pads to further.
The brake shoes use a similar heat-tolerant friction material to the pads used in disc brakes. Subsequent release of the brake pedal/lever allows the spring(s) in the master cylinder assembly to return the master piston(s) back into position.
Friction (pad/shoe) brakes are often rotating devices with a stationary pad and a rotating wear surface. Common configurations include shoes that contract to rub on the outside of a rotating drum, such as a band brake; a rotating drum with shoes that expand to rub the inside of a drum, commonly called a "drum brake", although other drum ...
An inboard brake is an automobile technology wherein the disc brakes are mounted on the chassis of the vehicle, rather than directly on the wheel hubs. Its main advantages are twofold: a reduction in the unsprung weight of the wheel hubs, as this no longer includes the brake discs and calipers; and braking torque is applied directly to the ...
