Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is turned off.
Gather necessary tools and parts.
Wear safety goggles and gloves for protection.

2. Check Brake Fluid Level

Open the hood and locate the brake master cylinder.
Inspect the fluid level; if low, top up with the manufacturer-recommended brake fluid (typically DOT 3 or DOT 4).
If fluid is significantly low, inspect for leaks before proceeding.

3. Inspect for Leaks

Visually inspect brake lines, calipers, and the master cylinder for any signs of fluid leaks.
Use a flashlight for better visibility.
If leaks are found, replace the affected components.

4. Bleed the Brake System

Locate the brake bleeder valves on each wheel.
Start with the wheel furthest from the master cylinder (usually the rear passenger side).
Attach a clear hose to the bleeder valve and place the other end in a container.
Have an assistant press the brake pedal several times and hold it down.
Open the bleeder valve to let fluid escape until clear fluid with no air bubbles flows through the hose.
Close the valve and have the assistant release the brake pedal.
Repeat for the other wheels in the following order: rear driver side, front passenger side, and front driver side.
Ensure brake fluid levels are topped off after bleeding.

5. Test Brake Booster

With the vehicle off, pump the brake pedal several times until it feels firm.
Hold the brake pedal down and start the engine; the pedal should drop slightly if the brake booster is functioning correctly.
If it does not drop, the brake booster may need to be replaced.
