Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Use wheel chocks to prevent movement.

2. Remove Wheel

Tools Required: Lug wrench, jack, jack stands
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 lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect the brake pads for wear indicators. If they are worn down to the metal, they need replacement.
Tools Required: Socket set, brake pad spreader
Remove the caliper bolts using the socket set and slide the caliper off the rotor.
Use the brake pad spreader to compress the caliper piston back into the caliper housing.
Remove old brake pads from the caliper bracket and replace with new pads, ensuring they are properly seated.

4. Inspect and Replace Rotors (if necessary)

Check the rotor's surface for scoring and warping. If damaged, replace the rotors.
Tools Required: Rotor puller (if necessary), torque wrench
Remove the caliper bracket bolts and take off the rotor.
Clean the hub surface with a wire brush if necessary, then install the new rotor.
Reattach the caliper bracket and torque bolts to the manufacturer's specifications.

5. Reassemble and Test

Reinstall the caliper over the new pads and torque the caliper bolts.
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a star pattern.
Test the brake pedal to ensure it feels firm before driving.
