Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery if working on electrical components.

2. Remove Wheel

Loosen lug nuts with a socket wrench before lifting the vehicle.
Use a jack to lift the vehicle and support it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Rotors

Inspection:
- Use a dial indicator to measure rotor run-out; if it exceeds specifications, replace the rotor.
Removal:
- Remove the caliper by unscrewing the caliper bolts; support it with a hanger to avoid strain on the brake line.
- Take off the rotor by removing any retaining screws and sliding it off the hub.
Replacement:
- Install the new rotor, ensuring it is properly aligned and secured.
- Clean the rotor surface with brake cleaner to remove any oils or contaminants.

4. Inspect and Replace Brake Pads

Check the thickness of the brake pads; if they are worn below the minimum thickness, replace them.
Remove the old pads by sliding them out of the caliper bracket.
Installation:
- Insert new pads into the caliper bracket.
- Compress the caliper piston using a brake caliper tool to allow space for the new pads.
- Reattach the caliper over the new pads and tighten caliper bolts to manufacturer specifications.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer's specifications using a torque wrench.
Reconnect the battery if it was disconnected.
