Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety goggles and gloves.

2. Check Brake Fluid

Remove the master cylinder cap to inspect the brake fluid level.
If low, add the appropriate brake fluid (DOT 3 or DOT 4, as specified in the owner’s manual).
Check for contamination in the brake fluid.

3. Inspect and Repair Leaks

Visually inspect all brake lines and hoses for any signs of damage or wear.
Tighten any loose connections or replace damaged sections of brake lines.
If leaks are found at the calipers, consider rebuilding or replacing them.

4. Replace the Brake Master Cylinder (if necessary)

Disconnect the battery to ensure safety while working.
Remove the brake fluid from the master cylinder using a syringe.
Disconnect the brake lines from the master cylinder using a wrench.
Remove the master cylinder mounting bolts and take out the old master cylinder.
Install the new master cylinder by reversing the removal steps, ensuring all connections are tight.

5. Bleed the Brake System

Begin at the wheel furthest from the master cylinder (usually the right rear).
Use a brake bleeder kit or have an assistant pump the brake pedal to build pressure.
Open the bleeder valve on the brake caliper until fluid flows without bubbles, then close the valve.
Repeat for each brake caliper in the order: right rear, left rear, right front, left front.
Check the brake fluid level and top off if necessary.
