Solution

1. Preparation

Tools Required: Socket set, torque wrench, jack and jack stands, brake cleaner, safety glasses, gloves.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery if working on electronic components.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Jack up the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Sub-steps:
- Remove the caliper bolts using the socket set and slide the caliper off the rotor.
- Support the caliper with a bungee cord or wire to avoid straining the brake line.
- Remove the old brake pads from the caliper bracket.
- Clean the caliper bracket and rotor with brake cleaner.
- Install new brake pads, ensuring they are positioned correctly in the caliper bracket.

4. Inspect and Replace Rotors (if necessary)

Sub-steps:
- Check rotor condition for any scoring or warping.
- If damaged, remove the rotor by unscrewing the retaining screw (if present) and pulling it off the hub.
- Install new rotors, ensuring they are properly seated and aligned.
- Torque the rotor retaining screw to the manufacturer's specifications.

5. Reassemble Brakes

Reattach the caliper over the new pads and rotors.
Tighten caliper bolts to the manufacturer’s torque specifications.
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Check

Lower the vehicle from the jack stands.
Tighten the lug nuts to the specified torque in a star pattern.
Reconnect the battery if it was disconnected.
