Solution

1. Preparation

Gather tools and materials needed.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety glasses and gloves.

2. Brake Fluid Inspection

Remove the master cylinder cap and check the brake fluid level.
If low, top off with the manufacturer-recommended brake fluid type (e.g., DOT 3 or DOT 4).
Inspect the fluid for contamination (dark color or debris).

3. Check for Leaks

Visually inspect brake lines, calipers, and wheel cylinders for any signs of fluid leaks.
If leaks are found, replace the faulty brake lines, calipers, or wheel cylinders as necessary.

4. Brake Booster Test

Disconnect the vacuum line from the brake booster.
Use a hand-held vacuum pump to test the brake booster; it should hold vacuum.
If it does not hold vacuum, replace the brake booster.

5. Brake Component Inspection

Remove the wheel and inspect the brake pads and rotors.
Replace worn brake pads and machine or replace rotors as necessary.
Ensure all components are properly lubricated and free of debris.

6. Bleed the Brake System

Begin at the furthest brake from the master cylinder (usually the passenger rear).
Use a brake bleeder kit or clear tubing to bleed each brake until no air bubbles are present.
Ensure to maintain brake fluid level in the master cylinder throughout the process.
