How to Replace the Rubber Cup in a Brake Wheel Cylinder?
1 Answers
The method for replacing the rubber cup in a brake wheel cylinder is as follows: 1. Release the car's handbrake and unscrew the bolt at the rear of the brake wheel cylinder until it can no longer be turned; 2. Tighten the handbrake, remove the wheel cylinder from the vehicle, and mark the upper and lower parts of the cylinder to avoid errors during reassembly; 3. Remove the two screws and nuts on the semi-circular part of the cylinder to expose the damaged rubber cup; 4. Directly replace it with a new rubber cup. The brake wheel cylinder is a part of the vehicle's braking system, primarily functioning to push the brake shoes against the brake drum, thereby slowing or stopping the car. When the driver applies the brakes, stepping on the brake pedal generates thrust in the master cylinder, which forces hydraulic fluid into the wheel cylinder, causing it to activate the brake shoes.
