Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts slightly.
Lift the vehicle using 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 check the rotor for warping (should be within manufacturer specifications).
Replacement (if needed):
- Remove the caliper bolts and lift the caliper off the rotor.
- Remove the rotor by unscrewing any retaining screws if applicable.
- Install the new rotor, ensuring it is seated correctly.
- Reinstall the caliper and torque the bolts to the manufacturer's specifications.

4. Inspect and Replace Brake Pads

Remove the caliper if not already done during rotor replacement.
Check brake pads for thickness and even wear.
If replacement is necessary, slide out the old pads and insert new ones into the caliper bracket.
Make sure to use brake grease on the backing of the pads to prevent squeaking.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications.
Reconnect the battery.
