Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it using wheel chocks.
Disconnect the battery to avoid any electrical issues during the repair.

2. Check and Refill Brake Fluid

Open the hood and locate the brake master cylinder.
Remove the cap and check the fluid level. If low, top it up with the recommended brake fluid (DOT 3 or DOT 4).
Replace the cap securely.

3. Inspect and Repair Leaks

Use a flashlight to inspect the brake lines, hoses, and connections for leaks.
If a leak is found, replace the damaged brake line or hose.
Ensure all connections are tight and free from corrosion.

4. Master Cylinder Inspection/Replacement

If no external leaks are found, test the master cylinder:
- Remove the master cylinder from the brake booster by unbolting it.
- Inspect for internal leaks by checking for fluid seepage around the seals.
If defective, replace with a new master cylinder and bench-bleed before installation.

5. Bleed the Brake System

Reconnect the master cylinder and fill with brake fluid.
Start bleeding the brakes at the farthest wheel from the master cylinder (usually the right rear), then move to the left rear, right front, and finally the left front.
Use a brake bleeder kit or have an assistant pump the brake pedal while you open and close the bleeder valves.
