Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Remove Wheel

Loosen lug nuts with a socket set.
Lift the vehicle with a jack and support it with jack stands.
Remove the wheel to access the brake assembly.

3. Inspect and Replace Brake Rotors

Inspection:
- Use a dial indicator to measure rotor runout; if it exceeds manufacturer's specifications, replace rotors.
Replacement:
- Remove the caliper by unscrewing the caliper mounting bolts.
- Slide the caliper off and support it without stressing the brake line.
- Remove the old rotor by unscrewing any retaining screws and sliding it off.
- Install the new rotor, ensuring it is properly seated and secured.

4. Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Clean the caliper bracket with brake cleaner.
Install new brake pads, ensuring they fit snugly in the bracket.

5. Reassemble and Test

Reinstall the caliper over the new pads and secure it with the mounting bolts (torque to manufacturer specifications).
Reattach the wheel and torque lug nuts in a star pattern.
Lower the vehicle and perform a test drive to verify the repair.
