Solution

1. Preparation

Gather tools and necessary parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Check and Refill Brake Fluid

Tools Required: Brake fluid, funnel
Inspect the brake fluid reservoir. If the fluid is low, refill it with the manufacturer's recommended brake fluid (usually DOT 3 or DOT 4).
Check for leaks in the brake lines if the fluid was low.

3. Inspect Brake Components

Tools Required: Jack and jack stands, wheel chocks, lug wrench
Lift the vehicle using a jack and secure it on jack stands.
Remove the wheels to access brake components.
Inspect the brake pads for wear; replace if they are below the manufacturer’s minimum thickness.
Check the rotors for scoring or warping; replace if necessary.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, clear tubing, container
Attach tubing to the bleeder screw on the brake caliper and place the other end in a container.
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder screw to release air and fluid, then close it before your assistant releases the pedal.
Repeat this process until no air bubbles are visible in the tubing.
Ensure the brake fluid reservoir remains full during this process.

5. Test the Brake Booster

Tools Required: Vacuum gauge (optional)
With the engine off, pump the brake pedal several times to deplete any vacuum.
Start the engine and press the brake pedal; it should feel firmer with the engine running.
If the pedal remains low, the brake booster may need replacement.
