Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety glasses and gloves.

2. Check Brake Fluid

Tools Required: Brake fluid, funnel
Remove the cap from the master cylinder reservoir.
Inspect the brake fluid level. If low, add the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).
Replace the cap securely.

3. Inspect and Repair Leaks

Tools Required: Wrench set, brake line wrench
Visually inspect all brake lines, hoses, and connections for signs of leakage.
If leaks are found, replace damaged brake lines or seals as necessary.
Tighten any loose connections to ensure a proper seal.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, container, wrench
Start with the brake farthest from the master cylinder (right rear, left rear, right front, left front).
Attach the bleeder kit to the brake bleeder valve on the caliper.
Open the valve and press the brake pedal slowly until fluid flows without bubbles.
Close the valve and repeat until all air is removed from that line.
Repeat for each brake line.
Ensure brake fluid level remains adequate during the bleeding process.

5. Inspect Brake Pads and Rotors

Tools Required: Jack, jack stands, wheel chocks, socket set
Lift the vehicle using a jack and secure it on jack stands.
Remove the wheels to access the brake components.
Inspect brake pads for thickness; replace if less than 3 mm.
Check rotors for grooves or warping; replace if necessary.

6. Test the Brake Booster

Tools Required: Vacuum gauge (if needed)
With the engine off, pump the brake pedal several times to deplete the vacuum.
Hold the brake pedal down and start the engine. The pedal should drop slightly if the booster is functioning properly.
If there's no change, inspect the vacuum hose for cracks or disconnects and replace the brake booster if needed.
