Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety goggles and gloves.

2. Check and Refill Brake Fluid

Locate the brake fluid reservoir.
Remove the cap and check fluid level; top up with appropriate brake fluid (DOT 4).
Replace the cap securely.

3. Inspect and Repair Brake Leaks

Visually inspect all brake lines, hoses, and fittings for signs of leakage.
If leaks are found, replace the damaged components using a wrench and appropriate replacement parts.

4. Replace the Brake Master Cylinder (if necessary)

Disconnect the negative battery terminal.
Remove any components obstructing access to the master cylinder.
Disconnect brake lines from the master cylinder using a line wrench.
Unbolt the master cylinder from the brake booster.
Install the new master cylinder by reversing the removal steps.
Ensure proper torque specifications (typically around 15-20 ft-lbs) when reattaching.

5. Bleed the Brake System

Start at the furthest wheel from the master cylinder (usually the right rear).
Attach a clear hose to the brake bleeder valve and submerge it in a container with brake fluid.
Have an assistant pump the brake pedal and hold it down; open the bleeder valve to release air and fluid, then close it before the pedal is released.
Repeat until fluid runs clear, then move to the left rear, right front, and finish with the left front wheel.
