Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface with the parking brake engaged.
Wear safety glasses and gloves.

2. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts from the wheel.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the brake pads; replace if less than 3mm.
- Look for uneven wear or damage.
Replace Brake Pads:
- Remove the caliper bolts using a socket set.
- Slide the caliper off the rotor and support it without stressing the brake line.
- Remove the old brake pads from the caliper bracket.
- Install new pads in the bracket, ensuring proper orientation.

4. Inspect and Replace Brake Rotors

Inspect Brake Rotors:
- Check for grooves, cracks, or warping; replace if necessary.
Replace Brake Rotors:
- Remove the caliper bracket if necessary to access the rotor.
- Remove the rotor by unscrewing the retaining screws or slides off if it's free.
- Install the new rotor, ensuring it sits flat against the hub.

5. Reassemble and Test

Reattach the caliper over the new pads and rotor, securing it with caliper bolts to manufacturer specifications (usually 20-30 ft-lbs).
Reinstall the wheel and lug nuts, tightening in a star pattern to the manufacturer's torque specifications (usually 100-130 ft-lbs).
Lower the vehicle and test the brakes by pressing the pedal several times before driving.
