Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and engage the parking brake.
Wear safety glasses and gloves.

2. Remove Wheel

Loosen the lug nuts before raising the vehicle.
Use a jack to lift the vehicle 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 run-out. If it exceeds 0.002 inches, replace the rotors.
Replacement:
- Remove the caliper by unbolting it from its bracket.
- Slide the caliper off the rotor and support it with a bungee cord or similar device.
- Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
- Install the new rotor, ensuring it is properly seated.
- Reattach the caliper, ensuring it is torqued to manufacturer specifications.

4. Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Compress the caliper piston using a brake caliper tool.
Install new brake pads, ensuring they are correctly oriented.
Reassemble the caliper over the new pads.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to manufacturer specifications.
Test the brakes by gently pressing the pedal to ensure they are functioning correctly before driving.
