Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety gloves and goggles.

2. Inspect and Repair Brake Lines

Inspect Lines: Visually check all brake lines and hoses for any signs of wear, cracks, or leaks.
Repair Leaks: If leaks are found, replace the affected brake line or hose using appropriate fittings.
- Tools Required: Wrench set, brake line flaring tool if necessary.

3. Check and Replace Brake Fluid

Check Level: If the brake fluid is low, add the specified brake fluid type (DOT 3 or DOT 4).
Replace Fluid: If contaminated, drain the old fluid and replace it with fresh fluid.
- Tools Required: Brake fluid container, turkey baster or fluid pump.

4. Bleed the Brake System

Bleeding Procedure:
1. Start with the brake furthest from the master cylinder (usually the right rear).
2. Attach a clear tube to the bleeder valve and submerge it in a container with brake fluid.
3. Have an assistant pump the brake pedal and hold it down.
4. Open the bleeder valve to allow fluid and air to escape, then close it before the pedal is released.
5. Repeat until fluid is clear and free of bubbles, then move to the next wheel.
Torque Specifications: Ensure all bleeder valves are tightened to manufacturer specifications after bleeding.

5. Inspect Brake Components

Brake Pads and Rotors: Check for wear and replace if necessary.
- Tools Required: Socket set, torque wrench.
