Solution

1. Preparation

Gather tools and safety equipment. Ensure the vehicle is parked on a level surface and the ignition is off.
Tools required:
- Jack and jack stands
- Lug wrench
- Torque wrench
- Brake cleaner
- Runout gauge
- Caliper tool (if necessary)
- Safety glasses and gloves

2. Remove Wheel

Using a lug wrench, loosen the lug nuts slightly while the vehicle is on the ground.
Jack up the vehicle and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Rotors

Inspect Rotor:
- Use a runout gauge to measure the rotor’s runout. If it exceeds manufacturer specifications, it needs replacement or resurfacing.
Replace Rotor (if necessary):
- Remove the caliper bolts and take off the caliper. Support it with a bungee cord or rope to avoid stressing the brake line.
- Remove the old rotor by unscrewing any retaining screws and sliding it off the hub.
- Install the new rotor and secure with retaining screws (if applicable).

4. Inspect and Replace Brake Pads

Check the brake pads for thickness and even wear. Replace if they are below the manufacturer’s minimum thickness.
Remove the old pads from the caliper bracket.
Clean the caliper bracket and apply brake lubricant to the contact points to prevent noise.
Install new brake pads, ensuring they are positioned correctly.

5. Reassemble and Bleed Brakes

Reattach the caliper over the new pads and tighten 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 specifications.
If brake fluid was lost during the process, bleed the brakes to remove any air from the system using a brake bleeder kit.
