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 goggles and gloves.

2. Inspect Brake Fluid

Open the hood and locate the brake fluid reservoir.
Check the fluid level; it should be between the "MIN" and "MAX" markings.
If low, top up with the recommended brake fluid type (DOT 3 or DOT 4 as specified in the owner's manual).

3. Check for Leaks

Visually inspect all brake lines, connections, and calipers for any signs of fluid leakage.
If leaks are found, replace damaged lines or components as necessary.

4. Examine Brake Pads

Remove the wheel using a lug wrench and socket set.
Inspect the brake pads for thickness; they should be at least 3mm thick.
If worn below this threshold, replace the brake pads.

5. Inspect Brake Rotors

Check the condition of the brake rotors for any grooves, scoring, or warping.
Measure the rotor thickness with a micrometer; if below the minimum thickness specified in the manual, replace the rotors.

6. Test Brake System

Reinstall the wheel and lug nuts, torqueing them to the manufacturer’s specifications.
Start the vehicle and press the brake pedal to check for firmness and travel.
If the brake pedal feels soft or has excessive travel, further inspection of the master cylinder or brake booster may be required.
