Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety glasses and gloves.

2. Remove the Wheel

Use a lug wrench to loosen the lug nuts slightly while the vehicle is on the ground.
Lift the vehicle using a jack and secure it on jack stands.
Remove the lug nuts and wheel to access the brake components.

3. Inspect and Replace Brake Rotors

Inspect Rotors:
- Use a dial indicator to measure rotor runout. If warping is detected (more than 0.002 inches), replacement is necessary.
Replace Rotors:
- Remove the caliper by unscrewing the bolts holding it in place.
- Slide the caliper off the rotor and support it using a bungee cord or rope to avoid straining the brake line.
- Remove the old rotor by unscrewing any retaining screws and sliding it off the hub.
- Install the new rotor, ensuring it is seated properly and secured with retaining screws.

4. Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Use a caliper tool to compress the caliper piston back into the caliper housing.
Install new brake pads into the caliper bracket ensuring correct orientation.
Reattach the caliper over the new pads and torque the caliper bolts to the manufacturer's specifications (usually around 25-35 ft-lbs).

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and torque the lug nuts to the manufacturer's specifications (usually around 80-100 ft-lbs).
Pump the brake pedal several times to ensure the pads seat correctly before driving.
