Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery if working on the brake system.

2. Remove Wheel

Loosen the lug nuts with a socket wrench.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Measure Brake Rotors

Use a dial indicator to check for rotor runout. Replace if warping exceeds manufacturer specifications (usually more than 0.05 mm).
If rotors are within specifications, clean the rotor surface with brake cleaner and a soft cloth.

4. Replace Brake Pads (if necessary)

Remove the caliper bolts using a socket wrench.
Carefully slide off the caliper and support it with a bungee cord (do not let it hang from the brake line).
Remove the old brake pads and inspect the caliper for sticking.
Install new brake pads, ensuring they are properly seated.

5. Reassemble

Reinstall the caliper and torque the caliper bolts to the manufacturer's specifications (typically 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specification (usually 80-100 ft-lbs).
