Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear appropriate safety gear (gloves, goggles).

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle based on the affected brakes.
Secure with jack stands for safety.

3. Remove Wheel

Use a socket set to remove the lug nuts and take off the wheel.
Store lug nuts in a safe place.

4. Inspect Brake Components

Brake Pads:
- Remove the caliper by unscrewing the caliper bolts.
- Check the thickness of the brake pads; replace if they are worn down to 3mm or less.
Brake Rotors:
- Inspect rotors for grooves or warping. If damaged, replace rotors.
- Measure rotor thickness; ensure it meets manufacturer specifications.

5. Replace Brake Pads and Rotors (if necessary)

Install new brake pads by positioning them in the caliper bracket.
If replacing rotors, remove the old rotor, clean the hub surface, and install the new rotor.
Torque caliper bolts to manufacturer specifications (typically around 30 Nm).

6. Reassemble and Lower Vehicle

Reattach the wheel and hand-tighten lug nuts.
Lower the vehicle and then torque the lug nuts to manufacturer specifications (typically around 120 Nm).

7. Final Checks

Refill brake fluid if necessary and bleed the brakes to remove any air.
Test the brake pedal for firmness before taking the vehicle for a test drive.
