Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the engine is off.
Wear safety glasses and gloves for protection.

2. Check Brake Fluid

Open the hood and locate the brake master cylinder.
Check the brake fluid level; refill with the appropriate brake fluid type (DOT 3 or DOT 4) if low.
Inspect for any signs of contamination in the fluid.

3. Inspect for Leaks

Look for brake fluid leaks along the brake lines, hose connections, and around the caliper.
If leaks are found, replace the damaged lines or components.

4. Bleed the Brake System

Locate the brake bleeder valves on each wheel's brake caliper.
Starting with the wheel farthest from the master cylinder, use a wrench to open the bleeder valve.
Have an assistant press the brake pedal down and hold it while you open the bleeder valve to allow air and old fluid to escape.
Close the valve before your assistant releases the pedal.
Repeat the process until no air bubbles appear in the fluid.
Ensure to check and top off the brake fluid reservoir after bleeding each wheel.

5. Test the Brake Booster

With the engine off, pump the brake pedal a few times to deplete the vacuum in the booster.
Start the engine and press the brake pedal; it should feel firm. If it remains spongy, the brake booster may need replacement.
