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 glasses and gloves.

2. Check and Top Off Brake Fluid

Open the hood and locate the brake master cylinder reservoir.
If the fluid level is low, add the appropriate brake fluid (DOT 3 or DOT 4 depending on the vehicle specification).
Close the reservoir cap securely.

3. Inspect Brake Components

Lift the vehicle using a jack and secure it on jack stands.
Remove the wheel to access brake components.
Visually inspect the brake pads for thickness (should be at least 1/4 inch) and check the rotors for grooves or scoring.

4. Bleed the Brake Lines

Locate the brake bleeder screws on each brake caliper.
Attach a clear hose to the bleeder screw and place the other end in a container.
Have an assistant pump the brake pedal several times, then hold it down.
Open the bleeder screw to release air and fluid, then close it before the assistant releases the pedal.
Repeat until no air bubbles appear in the fluid, and ensure to check fluid levels in the reservoir during this process.

5. Brake Booster Inspection

With the engine running, depress the brake pedal several times to deplete vacuum pressure.
Hold the pedal down and start the engine; the pedal should drop slightly if the brake booster is functioning properly.
If it does not, the brake booster may need replacement.
