Solution

1. Preparation

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

2. Remove the Wheel

Use a lug wrench to loosen the lug nuts slightly while the vehicle is on the ground.
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 Replace Brake Rotors

Inspect: Check the rotors for warping or uneven wear using a dial indicator.
Replace (if necessary):
- Use a rotor removal tool or a hammer and block of wood to gently tap the rotors off the hub.
- Clean the hub surface with brake cleaner to remove debris.
- Install new rotors, ensuring they are properly seated and aligned.
- Torque the rotor retaining screws to the manufacturer's specifications.

4. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts using a socket set.
Support the caliper with a bungee cord or similar method to avoid strain on the brake line.
Remove old brake pads from the caliper bracket.
Replace: Install new brake pads, ensuring they are positioned correctly in the caliper bracket.
Reattach the caliper and torque the caliper bolts to the manufacturer's specifications.

5. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands.
Torque the lug nuts to the manufacturer's specifications in a crisscross pattern.
