Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and set the parking brake.
Disconnect the battery to eliminate any electrical hazards.

2. Check and Refill Brake Fluid

Open the hood and locate the brake fluid reservoir.
Remove the cap and check the fluid level; top off with the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
Replace the cap securely.

3. Inspect and Replace Leaking Components

If leaks are found in brake lines or at the master cylinder, replace the damaged sections:
- Brake Lines: Use a line wrench to disconnect and remove the damaged line. Install the new line and torque to the manufacturer’s specifications.
- Master Cylinder: Disconnect brake lines and remove the mounting bolts. Install the new master cylinder, ensuring all connections are secure and torque to specifications.

4. Bleeding the Brake System

Begin at the wheel furthest from the master cylinder (usually the right rear):
1. Attach a clear hose to the bleeder valve on the brake caliper.
2. Place the other end of the hose in a container partially filled with brake fluid.
3. Have an assistant pump the brake pedal several times and hold.
4. Open the bleeder valve to release air and fluid, then close the valve before the assistant releases the pedal.
5. Repeat until fluid runs clear with no bubbles.
6. Move to the next wheel in the order: right rear, left rear, right front, left front.

5. Final Inspection

Check the brake fluid level again and top off as necessary.
Reconnect the battery.
Test the brake pedal for firmness and proper operation.
