Solution

1. Preparation

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

2. Inspect and Top Off Brake Fluid

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if it’s below the minimum line, top it off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Close the reservoir cap securely.

3. Check Brake Lines and Calipers

Visually inspect brake lines for any signs of fluid leaks or damage.
Inspect brake calipers for leaks and ensure they are not stuck or damaged.
If leaks are found, replace the affected brake lines or calipers as necessary.

4. Bleed the Brake System

Locate the brake bleeder screws on each caliper.
Use a wrench to open the bleeder screw while an assistant depresses the brake pedal.
Allow fluid to flow until no air bubbles are visible, then close the screw.
Repeat this process for each wheel, ensuring to start from the wheel farthest from the master cylinder.
Monitor the brake fluid level in the reservoir and top off as necessary.

5. Replace Brake Pads or Rotors (if needed)

If brake pads or rotors show excessive wear, remove the wheel and caliper.
Remove old brake pads and replace them with new ones.
If needed, machine or replace rotors according to specifications.
Reinstall calipers and ensure they are properly torqued.

6. Test Brake Booster

With the engine running, pump the brake pedal several times to deplete the brake booster.
Hold the brake pedal down; the pedal should remain firm. If it sinks, the brake booster may be faulty and should be replaced.
