Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface, and the engine is off.
Wear safety gloves and goggles.

2. Check Brake Fluid

Remove the master cylinder cap and inspect the brake fluid level.
If low, top off with manufacturer-recommended brake fluid (DOT 3 or DOT 4).
If the fluid is contaminated, proceed to the next step to flush the system.

3. Inspect and Repair the Brake Booster

Remove the Brake Booster:
- Disconnect the negative battery terminal.
- Remove the vacuum line from the brake booster.
- Unbolt the brake booster from the firewall (usually requires a socket set).
Test the Booster:
- Use a vacuum pump to test the brake booster. If it does not hold vacuum, it needs replacement.
Install New Brake Booster (if necessary):
- Place the new brake booster into position and secure it with bolts to the firewall.
- Reconnect the vacuum line and ensure it is tight.

4. Brake System Inspection

Inspect all brake lines for leaks and replace any damaged sections.
Replace brake pads and rotors if they are worn beyond specifications.
Bleed the brake system to remove any air bubbles after repairs.

5. Reassemble and Test

Reconnect the master cylinder cap securely.
Reconnect the negative battery terminal.
Test the brake pedal feel before starting the vehicle.
