Solution

1. Preparation

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

2. Inspect and Refill Brake Fluid

Sub-steps:
1. Open the hood and locate the brake fluid reservoir.
2. Check the fluid level; if low, add the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
3. Inspect the reservoir cap for proper sealing to prevent moisture contamination.

3. Identify and Repair Leaks

Sub-steps:
1. Visually inspect all brake lines from the master cylinder to the calipers for signs of wear or damage.
2. If leaks are found, replace the damaged brake line or hose.
3. Tighten any loose fittings and ensure no fluid is leaking from the brake calipers.

4. Replace the Master Cylinder (if necessary)

Sub-steps:
1. Disconnect the negative battery terminal to prevent electrical shorts.
2. Remove any components obstructing access to the master cylinder.
3. Disconnect the brake lines from the master cylinder using a flare nut wrench.
4. Unbolt the master cylinder and remove it from the brake booster.
5. Install the new master cylinder, ensuring to torque the bolts to manufacturer specifications.
6. Reconnect the brake lines and bleed the brake system.

5. Bleed the Brake System

Sub-steps:
1. Use a brake bleeder kit or have an assistant pump the brake pedal.
2. Start with the wheel farthest from the master cylinder and work towards the nearest.
3. Open the bleeder valve, allowing air and fluid to escape, then close the valve before releasing the pedal.
4. Repeat until no air bubbles are present in the fluid.
