Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a flat surface and secured with wheel chocks.
Wear safety gloves and goggles.

2. Remove Wheel

Use a jack to lift the vehicle and secure it on jack stands.
Loosen the lug nuts using a socket wrench and remove the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check for thickness; replace if they are below 3mm.
- Look for uneven wear or scoring.
Replace Brake Pads:
- Remove caliper bolts using a socket wrench.
- Slide caliper off the rotor and suspend it with a bungee cord (do not let it hang by the brake line).
- Remove old brake pads from the caliper bracket.
- Install new brake pads, ensuring proper orientation.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Look for grooves or excessive wear; measure thickness with a micrometer.
Replace Rotors:
- Remove the caliper bracket if needed.
- Unscrew the rotor from the hub.
- Install new rotor, securing it with screws if applicable.

5. Reassemble and Test

Reattach the caliper over the new brake pads and torque caliper bolts to manufacturer specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to specifications.
Pump the brake pedal to ensure proper brake engagement before test driving.
