Brake System Parts

Brake drums and discs, pads, linings and rivets, S-cams, slack adjusters, brake chambers, air compressors, dryers, valves and wear sensors.

Features

Drums and discs carry a wear limit marked on the part, and a machined drum past that diameter cracks under heat.
Friction material is matched to the vehicle's brake specification, because a different friction coefficient changes braking balance across axles.
Air dryer cartridges are a service item; wet air damages valves and chambers throughout the system.
Automatic slack adjusters are inspected for free stroke rather than assumed to be working, as a seized adjuster quietly removes braking at that wheel.
The system is leak-tested and stroke-checked after any brake component change.
