Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Inspect and Replace Brake Lines

Tools Required: Wrench set, brake line removal tool, flare nut wrench.
Identify any damaged brake lines or hoses.
Use the wrench to loosen the fittings and carefully remove the faulty brake line.
Replace with a new brake line or hose, ensuring proper routing and securing.
Torque fittings to manufacturer specifications (typically 12-15 ft-lbs for brake lines).

3. Replace Brake Master Cylinder (if necessary)

Tools Required: Socket set, torque wrench, brake fluid.
Remove the brake lines from the master cylinder using a flare nut wrench.
Unscrew the mounting bolts securing the master cylinder to the brake booster.
Replace with a new master cylinder, ensuring it is aligned properly.
Reattach brake lines and torque to manufacturer specifications.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, fresh brake fluid, clear tubing.
Fill the brake master cylinder reservoir with new brake fluid.
Start bleeding from the wheel farthest from the master cylinder (typically the right rear).
Attach the tubing to the bleeder valve and have an assistant pump the brake pedal.
Open the bleeder valve to allow fluid and air to escape, then close it.
Repeat until no air bubbles are seen in the fluid stream.
Proceed to the next wheel until all are bled.
