Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety gloves and goggles for protection.

2. Check and Refill Brake Fluid

Tools Required: Brake fluid, funnel, cleaning cloth.
Locate the master cylinder reservoir and remove the cap.
Check the fluid level; if low, refill with the recommended DOT fluid (usually DOT 3 or DOT 4).
Clean the reservoir cap and replace it securely.

3. Inspect for Leaks

Tools Required: Flashlight, inspection mirror.
Inspect brake lines, calipers, and wheel cylinders for signs of fluid leaks.
If leaks are found, replace the damaged components and ensure all connections are tight.

4. Bleed the Brake System

Tools Required: Brake bleeder kit or clear tubing, catch container.
Start at the brake furthest from the master cylinder (usually rear passenger side).
Attach the tubing to the bleeder valve and submerge the other end in the catch container with some brake fluid.
Have an assistant pump the brake pedal several times, then hold it down.
Open the bleeder valve to release air and fluid, then close it before the pedal is released.
Repeat until no air bubbles are present, then move to the next brake in the order: rear driver side, front passenger side, and finally front driver side.

5. Test Brake Booster

Tools Required: Vacuum gauge.
With the engine off, pump the brake pedal several times to deplete vacuum.
Hold the brake pedal down and start the engine; if the pedal sinks slightly, the booster is functioning correctly.
If there is no change, further inspection or replacement of the brake booster may be necessary.
