Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical issues.

Tools Required:

Socket set
Brake fluid
Brake line wrench
Torque wrench
Brake bleeder kit
Clean rags

2. Check and Refill Brake Fluid

Open the brake master cylinder reservoir cap.
If the fluid is low, add the appropriate brake fluid (DOT 3 or DOT 4 as specified).
Replace the cap securely after filling.

3. Inspect for Leaks

Visually inspect all brake lines, connections, and the master cylinder for leaks.
Tighten any loose fittings and replace any damaged brake lines or components as necessary.

4. Bleed the Brake System

Begin by bleeding the furthest brake from the master cylinder (usually the rear passenger side).
Attach the brake bleeder kit to the brake bleeder valve.
Have an assistant press the brake pedal while you open the valve to release air and old fluid.
Close the valve before the assistant releases the pedal.
Repeat until clear fluid with no air bubbles flows out, then move to the next wheel.
Ensure to bleed all four brakes and check fluid level in the master cylinder frequently.

5. Replace the Brake Master Cylinder (if necessary)

If leaks are found in the master cylinder, proceed to replace it:
- Remove the brake lines connected to the master cylinder using a brake line wrench.
- Unbolt the master cylinder from the brake booster.
- Install the new master cylinder by reversing the removal steps.
- Reconnect the brake lines and torque to the manufacturer’s specifications.
