Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to avoid electrical issues during repairs.

2. Check Brake Fluid and Lines

Tools Required: Brake fluid tester, wrench set
- Remove the master cylinder cap and check the brake fluid level; top off if necessary.
- Inspect the brake lines and connections for any leaks or damage. Repair or replace as needed.

3. Inspect and Test Brake Booster

Tools Required: Vacuum gauge, socket set
- Disconnect the vacuum line from the brake booster and inspect for cracks or damage. Replace if necessary.
- Attach a vacuum gauge to the brake booster fitting to check for proper vacuum levels (should be around 18-22 inHg). If vacuum is insufficient, the booster may need replacement.

4. Inspect Brake Pads and Rotors

Tools Required: Jack and jack stands, lug wrench, brake caliper tool
- Lift the vehicle and remove the wheel to access the brake components.
- Inspect brake pads for thickness; replace if worn below 3mm.
- Check rotors for scoring or warping; machine or replace as necessary.

5. Reassemble and Refill

Reinstall the brake components in reverse order of removal.
Refill the brake fluid to the appropriate level in the master cylinder.
Reconnect the battery.
