Solution

1. Preparation

Gather tools and materials: brake cleaner, torque wrench, socket set, jack and jack stands, dial indicator, and replacement parts if needed.
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Rotors

Inspection:
- Use a dial indicator to measure rotor runout; if the reading exceeds manufacturer specifications, replacement is necessary.
Replacement:
- Remove caliper bolts and slide the caliper off (support it with a bungee cord to avoid straining the brake line).
- Remove the old rotor by unscrewing any retaining screws or removing clips.
- Clean the hub surface with brake cleaner to ensure proper seating of the new rotor.
- Install the new rotor, securing it with retaining screws if applicable.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Inspect the caliper for proper operation and ensure it slides freely on the bracket.
Install new brake pads, ensuring they are oriented correctly and seated properly.

5. Reassemble and Torque

Reattach the caliper over the new pads, tightening the caliper bolts to the manufacturer’s torque specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
