Solution

1. Preparation

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

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove lug nuts using a socket wrench and take off the wheel.

3. Inspect and Replace Brake Pads

Inspection:
- Remove the caliper bolts with a socket wrench.
- Slide the caliper off the rotor and suspend it using a bungee cord (do not let it hang by the brake line).
- Inspect brake pads for thickness; replace if less than 3mm.
Replacement:
- Remove old brake pads from the caliper bracket.
- Install new brake pads in the caliper bracket.
- Apply brake grease on the back of new pads to reduce noise.

4. Inspect and Replace Brake Rotors

Inspection:
- Check rotors for deep grooves or uneven wear; measure thickness with a micrometer.
Replacement:
- If necessary, remove the rotor by unscrewing the retaining screws and sliding it off the hub.
- Install new rotors, ensuring they are clean and free of grease.
- Torque the rotor screws to manufacturer specifications.

5. Reassemble Braking System

Reattach the caliper over the new pads and rotor.
Tighten the caliper bolts to the specified torque value.
Reinstall the wheel and lug nuts, tightening them in a star pattern.

6. Test Brakes

Lower the vehicle from jack stands.
Press the brake pedal several times to seat the brake pads against the rotors.
Conduct a low-speed brake test to ensure proper operation and listen for any noises.
