Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Lift the vehicle using a jack and support with jack stands.

2. Remove Wheel

Using a lug wrench, loosen and remove the lug nuts.
Take off the wheel to access the braking components.

3. Inspect and Replace Brake Rotors

Inspection: Use a dial indicator to measure rotor runout; if it exceeds manufacturer specifications, replace.
Replacement:
1. Remove the caliper by unscrewing the caliper bolts.
2. Remove the old rotor by unscrewing any retaining screws and sliding it off the hub.
3. Clean the hub surface with a wire brush to ensure a flat mounting surface.
4. Install the new rotor, ensuring it sits flush against the hub.
5. Reattach the caliper and torque bolts to manufacturer specifications (usually around 25-30 ft-lbs).

4. Inspect and Replace Brake Pads

Remove old brake pads from the caliper bracket.
Inspect the caliper slides and lubricate if necessary.
Install new brake pads, ensuring they are seated properly in the caliper bracket.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to manufacturer specifications (typically 80-100 ft-lbs).
Pump the brake pedal to ensure proper pad seating before test driving.
