Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery for safety.

2. Remove Wheel Assembly

Use a lug wrench to loosen and remove the lug nuts from the affected wheel.
Lift the vehicle using a jack and secure it on 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 exceeding manufacturer specifications, replace the rotors.
Replacement:
- Remove the caliper bolts using a socket wrench.
- Slide the caliper off the rotor and secure it to the suspension using a hanger.
- Remove the rotor retaining screws (if applicable) and slide the rotor off the hub.
- Install the new rotor, securing it with screws.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Clean the caliper bracket and apply anti-squeal grease to the backing of the new pads.
Install new brake pads in the caliper bracket.

5. Reassemble Components

Reattach the caliper over the new pads and torque caliper bolts to manufacturer specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specified value.

6. Final Check

Reconnect the battery.
Pump the brake pedal to ensure proper brake pad seating.
