Solution

1. Preparation

Tools Required: Wheel chocks, jack and jack stands, lug wrench, torque wrench, brake cleaner, caliper tool.
Safely park the vehicle on a flat surface and engage the parking brake.
Place wheel chocks behind the rear wheels to prevent movement.

2. Remove the Wheel

Loosen the lug nuts with the lug wrench.
Raise the vehicle using the jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set and carefully slide the caliper off the rotor.
If the pads are worn below the manufacturer’s specifications (usually 3mm or less), replace them.
- Sub-steps:
  - Remove the old brake pads from the caliper bracket.
  - Clean the caliper and bracket with brake cleaner.
  - Install new brake pads, ensuring correct orientation and fit.

4. Inspect and Resurface/Replace Rotors

Check the rotor surface for grooves or scoring.
If the rotors are within specification, they can be resurfaced; otherwise, replace them.
- Sub-steps for Replacement:
  - Remove the caliper bracket bolts and take off the bracket.
  - Remove the rotor from the hub.
  - Install the new rotor, ensuring it is seated correctly.

5. Reassemble and Secure Components

Reinstall the caliper bracket and torque the bolts to the manufacturer’s specifications (usually around 80-90 lb-ft).
Slide the caliper back over the new pads and secure it in place.
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower the Vehicle and Torque Lug Nuts

Carefully lower the vehicle from the jack stands.
Once on the ground, use the torque wrench to tighten the lug nuts to the manufacturer’s specifications (typically 80-100 lb-ft).
