Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety gloves and goggles for protection.

2. Remove Wheel

Sub-steps:
1. Loosen the lug nuts using a socket wrench.
2. Raise the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Carefully lift the caliper and support it with a bungee cord or rope to avoid strain on the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Inspect the brake pad backing plates for damage; replace if necessary.
5. Install new brake pads, ensuring they are properly aligned.

4. Inspect and Replace Brake Rotors (if needed)

Sub-steps:
1. Check the rotor for scoring or excessive wear; if damaged, remove the rotor.
2. Remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
3. Install new rotors by aligning them on the hub and securing with screws.
4. Clean the rotor surface with brake cleaner before reassembly.

5. Reassemble

Sub-steps:
1. Reinstall the caliper over the new brake pads.
2. Tighten caliper bolts to the manufacturer's torque specifications.
3. Reattach the wheel and hand-tighten the lug nuts.
4. Lower the vehicle and then fully tighten the lug nuts in a crisscross pattern.
