Working Principle
The brake wheel cylinder is mounted on the brake backing plate and connected to the master cylinder via brake fluid lines. When the brake pedal is depressed, hydraulic pressure pushes the piston outward, transmitting force through the push rod to expand brake shoes against the rotating drum. When released, return springs pull the piston back, separating the shoes from the drum.
Failure Symptoms
| Symptom | Probable Cause |
|---|---|
| Reduced braking performance | Worn internal seals; hydraulic leakage; insufficient braking force |
| Vehicle pulls to one side during braking | Single-side cylinder malfunction; uneven braking force |
| Brake drag after pedal release | Stuck piston; cylinder fails to return |
| Visible brake fluid leakage | Worn/damaged cylinder seals |
| Soft or spongy brake pedal | Internal leakage or air in hydraulic system |
