Solution

1. Preparation

Gather tools and materials: socket set, torque wrench, brake cleaner, and replacement pads/rotors if needed.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery for safety before starting work.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Lift the vehicle using a jack and secure with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor and support it with a bungee cord (do not hang by the brake line).
- Remove the old brake pads and check their thickness.
Replace Brake Pads:
- Clean the caliper bracket and rotor with brake cleaner.
- Install new brake pads in the caliper bracket, ensuring they are oriented correctly.
- Compress the caliper piston using a C-clamp or caliper tool to fit over the new pads.
- Reattach the caliper and torque the bolts to the manufacturer's specifications.

4. Inspect and Replace Brake Rotors (if necessary)

If the rotors are damaged, remove them by unscrewing any retaining screws and sliding them off the hub.
Install new rotors and ensure they are clean.
Reassemble the caliper and pads as described above.

5. Reassemble and Test

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and tighten the lug nuts to the proper torque specification in a criss-cross pattern.
Reconnect the battery.
