Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the engine turned off.
Engage the parking brake for safety.

2. Check and Top Off Brake Fluid

Locate the master cylinder reservoir.
Inspect the fluid level; if low, top off with the manufacturer-recommended brake fluid (usually DOT 3 or DOT 4).
Check for any visible leaks around the reservoir and brake lines.

3. Inspect Brake Pads and Rotors

Remove the wheel using a socket set.
Inspect brake pads for thickness; replace if worn down to 3mm or less.
Measure rotor thickness and check for grooves or scoring; replace if below minimum thickness or excessively damaged.
Use a torque wrench to reattach the wheel bolts to the manufacturer’s specifications.

4. Check Brake Lines and Hoses

Visually inspect all brake lines and hoses for cracks or leaks.
Replace any damaged or corroded lines using appropriate brake line tools.
Ensure all connections are secure and free of leaks.

5. Test Brake Booster

With the engine off, pump the brake pedal several times; it should feel firm.
Start the engine; the brake pedal should drop slightly, indicating the booster is functioning.
If not, replace the brake booster as needed.
