Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, torque wrench, socket set.
Safety Warnings: Ensure the vehicle is on a level surface and the parking brake is engaged. Always wear safety glasses and gloves.

2. Lift the Vehicle

Use the jack to lift the vehicle and secure it on jack stands.
Remove the wheel using the lug wrench.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts with the socket set and take off the caliper.
2. Slide out the old brake pads from the caliper bracket.
3. Inspect the new brake pads for proper fit and thickness.
4. Apply brake grease to the back of the new pads to reduce noise.
5. Install the new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if needed)

Sub-steps:
1. Check the rotor surface for scoring or wear; if damaged, replace the rotor.
2. Remove the caliper bracket bolts and take off the bracket.
3. Slide off the rotor from the hub; if stuck, use a hammer gently around the edges.
4. Install the new rotor onto the hub.
5. Reattach the caliper bracket and torque the bolts to manufacturer specifications.

5. Reassemble

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

6. Lower the Vehicle

Carefully lower the vehicle back to the ground and fully tighten the lug nuts in a star pattern.
