Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if necessary to prevent electrical shorts.

2. Remove Wheel Assembly

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

3. Inspect and Replace Brake Rotors

Inspection:
- Use a dial indicator to measure rotor runout; if greater than 0.002 inches, consider resurfacing or replacing.
Replacement:
- Remove caliper bolts and lift the caliper off the rotor.
- Secure the caliper to avoid stress on the brake line.
- Remove the old rotor; install the new rotor ensuring correct alignment.
- Torque rotor mounting hardware to manufacturer specifications.

4. Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Clean the caliper bracket and apply brake grease to the contact points.
Install new brake pads ensuring they are seated correctly.
Reattach the caliper and torque bolts to manufacturer specifications.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to manufacturer specifications.
Reconnect the battery if it was disconnected.
