Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Place wheel chocks behind the rear wheels for safety.

2. Inspect and Replace Brake Fluid

Remove the brake fluid reservoir cap.
If the fluid is low, top it off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
If the fluid appears contaminated, proceed to replace it by bleeding the brake lines.

3. Check and Repair the Brake Booster

Locate the brake booster assembly.
Inspect the vacuum line for cracks or disconnections. If damaged, replace the line.
Disconnect the brake booster from the master cylinder by removing the mounting nuts (typically 10mm).
Remove the brake booster from its mounting location.
Install the new or repaired brake booster, ensuring all connections are secure.

4. Inspect Brake Pedal Assembly

Remove any covers necessary to access the brake pedal assembly.
Check for proper movement and ensure there are no obstructions.
Lubricate pivot points if necessary, using a suitable lubricant.

5. Reassemble and Test

Reattach the brake booster to the master cylinder and tighten the nuts to the manufacturer’s specified torque value (typically around 10-15 ft-lbs).
Replace any covers or panels removed during the inspection.
Refill brake fluid if necessary and ensure the reservoir cap is secure.
