What are the symptoms of a faulty air brake chamber?

[BellaLee]

The symptoms of a faulty air brake chamber include oil leakage at the connection between the chamber and the oil pipe, a soft feeling when stepping on the brake pedal, and the steering wheel noticeably pulling to one side after pressing the brake pedal. Brake fluid leakage: Since brake fluid is the force transmitter, without it, force cannot be transmitted, resulting in no braking. Brake fluid leakage is uncommon because the pipelines are mostly made of metal and are not prone to rupture. However, a small section of the pipeline near the brake chamber is made of rubber, so leaks often occur here due to rubber aging or external force-induced rupture. Brake pad failure: Brake pads may be worn out or their friction coefficient may decrease due to overheating. Since brake pads are the terminal executors of braking, their absence naturally leads to brake failure. On long downhill sections, prolonged braking can cause surface overheating, significantly reducing the friction coefficient and preventing the generation of sufficient friction force, thus resulting in braking failure.
