Solution

1. Preparation

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

2. Check Brake Fluid Level

Locate the brake fluid reservoir (usually near the back of the engine bay).
Open the cap and visually inspect the fluid level.
If low, top up with the recommended brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).

3. Inspect Brake Components

Remove the wheel to access the brake caliper and rotor.
- Tools: Jack, jack stands, lug wrench.
Inspect the brake pads for thickness. Replace if they are worn down to 3mm or less.
Check the brake rotors for scoring or warping. Replace if necessary.

4. Inspect Brake Lines and Hoses

Follow the brake lines from the master cylinder to each wheel.
Look for any signs of fluid leaks or cracks in the lines or hoses.
Replace any damaged lines or hoses using appropriate brake line fittings.

5. Test Brake Booster

With the engine off, pump the brake pedal several times to exhaust the vacuum.
Hold the pedal down and start the engine. The pedal should drop slightly. If it doesn’t, the brake booster may be faulty and should be replaced.

6. Address ABS Issues

If the ABS warning light is illuminated, check the ABS fuses and relays.
Use a multimeter to test the wheel speed sensors for proper voltage.
Replace any faulty sensors or components in the ABS system.
