Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on level ground and secure it with wheel chocks.
Disconnect the negative battery terminal for safety.

2. Inspect and Repair Leaks

Sub-steps:
- Visually inspect all brake lines and fittings for leaks.
- If a leak is found, replace the damaged line or fitting.
- Check the brake calipers and wheel cylinders for signs of leakage and replace if necessary.

Tools Required: Wrench set, brake line wrench, fluid catch pan

3. Bleed the Brake System

Sub-steps:
- Fill the master cylinder reservoir with fresh brake fluid.
- Starting from the wheel furthest from the master cylinder (usually the right rear), attach a brake bleeder kit to the brake bleeder valve.
- Open the bleeder valve and have an assistant pump the brake pedal until no air bubbles are seen in the fluid. Close the valve and repeat at each wheel in the correct order (right rear, left rear, right front, left front).

Tools Required: Brake bleeder kit, wrench for bleeder valves

4. Replace the Master Cylinder (if necessary)

Sub-steps:
- Remove the master cylinder by unbolting it from the brake booster and disconnecting the brake lines.
- Install the new master cylinder and torque the bolts to the manufacturer's specifications (typically around 15-20 ft-lbs).
- Reconnect the brake lines and bleed the system again to remove any air.

Tools Required: Socket set, torque wrench
