Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, dial indicator, torque wrench, brake cleaner, impact wrench (if available).
Ensure the vehicle is on a level surface and the parking brake is engaged.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the wheel completely.

3. Inspect Brake Rotors

Runout Measurement: Attach the dial indicator to the brake caliper. Rotate the rotor and note the runout measurement.
If runout exceeds manufacturer specifications (typically over 0.002 inches), the rotor is warped and needs resurfacing or replacement.

4. Replace Brake Rotors (if necessary)

Remove caliper bolts and carefully detach the caliper from the rotor.
Hang the caliper using a wire to avoid stress on the brake line.
Remove the rotor by taking off any retaining screws or clips.
Install the new rotor, ensuring it is seated properly.
Reinstall the caliper and torque bolts to manufacturer specifications (typically 80-100 ft-lbs).

5. Replace Brake Pads (if necessary)

Remove old brake pads from the caliper bracket.
Clean the caliper bracket and apply brake grease to contact points.
Install new brake pads, ensuring proper orientation.
Reattach the caliper over the new pads.

6. Reassemble and Test

Reinstall the wheel and torque lug nuts to manufacturer specifications (typically 100-120 ft-lbs).
Lower the vehicle from the jack stands.
Pump the brake pedal to seat the pads before driving.
