Solution

1. Preparation

Gather required tools and parts before starting the repair.
Tools Required: Socket set, brake fluid, vacuum pump (if needed), multimeter.
Safety Warnings: Always wear safety glasses when working on brakes and ensure the vehicle is secured on a flat surface.

2. Check Brake Fluid Level

Open the hood and locate the brake master cylinder.
Remove the cap and visually inspect the brake fluid level.
If low, top up with the recommended brake fluid type (DOT 3 or DOT 4 depending on the model).

3. Inspect Brake Booster

Locate the brake booster attached to the master cylinder.
Check vacuum hose connections to ensure they are tight and not cracked.
If necessary, disconnect the vacuum hose and apply a vacuum pump to the booster; it should hold vacuum. If it does not, the booster may be faulty.

4. Replace Brake Booster (if necessary)

If the brake booster is determined to be faulty, proceed with replacement:
1. Disconnect the negative battery cable.
2. Remove the master cylinder from the brake booster by unbolting and pulling it away.
3. Unbolt the brake booster from the firewall and remove it from the vehicle.
4. Install the new brake booster, ensuring proper alignment with the mounting holes.
5. Reattach the master cylinder to the new booster, tightening bolts to manufacturer specifications (usually 15-20 ft-lbs).

5. Final Check

Reconnect the negative battery cable.
Bleed the brake system to ensure no air is trapped (start with the wheel furthest from the master cylinder).
Test the brake pedal feel before driving.
