Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Use wheel chocks to prevent movement.

2. Remove Wheel

Loosen lug nuts with a socket set before raising the vehicle.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Rotors

Inspect Rotors:
- Use a dial indicator to measure rotor runout. If it exceeds specifications, replace the rotor.
Replace Rotors:
- Remove the caliper bolts and carefully slide the caliper off the rotor.
- Remove the old rotor and install the new rotor, ensuring it is properly seated.
- Reinstall the caliper and torque bolts to the manufacturer’s specifications (typically around 70-80 ft-lbs).

4. Inspect and Replace Brake Pads

Inspect Pads:
- Check the thickness of the brake pads; replace if less than 3mm.
Replace Pads:
- Remove the clips and slide the old pads out of the caliper bracket.
- Install new brake pads, ensuring they are oriented correctly and properly seated.
- Reinstall clips and ensure everything is secure.

5. Reassemble and Test

Reinstall the wheel and tighten lug nuts to the manufacturer's torque specification (typically around 100-110 ft-lbs).
Lower the vehicle and remove wheel chocks.
Test brake operation by performing a low-speed brake test to ensure no shuddering occurs.
