Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is on a flat surface and secure it with wheel chocks.
• Disconnect the battery to prevent electrical issues.

2. Inspect and Repair Brake Lines

• Tools Required: Wrench set, brake line fittings.
  • Check all brake lines and connections for leaks.
  • Replace any damaged or corroded lines and fittings. Ensure fittings are tightened to the manufacturer’s specifications.

3. Replace Master Cylinder (if necessary)

• Tools Required: Socket set, brake line wrench, torque wrench.
  • Locate the master cylinder on the brake booster.
  • Disconnect the brake lines using a brake line wrench to avoid damaging them.
  • Unbolt the master cylinder from the brake booster and remove it.
  • Install the new master cylinder, torquing bolts to manufacturer specifications.
  • Reconnect brake lines ensuring there are no leaks.

4. Bleed the Brake System

• Tools Required: Brake bleeder kit, clear tubing.
  • Starting with the wheel farthest from the master cylinder, attach the clear tubing to the bleeder valve.
  • Open the valve and depress the brake pedal until fluid flows through the tubing, then close the valve.
  • Repeat for all wheels in the correct order (typically rear passenger, rear driver, front passenger, front driver).
  • Check the brake fluid level in the master cylinder and top off as necessary.

5. Final Checks

• Reconnect the battery.
• Test the brake pedal for firmness before driving.
