Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Remove Wheel

Sub-steps:
1. Loosen lug nuts using a lug wrench while the vehicle is still on the ground.
2. Lift the vehicle using a jack and secure with jack stands.
3. Remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Sub-steps:
1. Inspect brake pads for thickness; replace if less than 3mm.
2. Check rotors for grooves or uneven wear; replace if necessary.
3. Examine calipers for proper operation and signs of leakage.

4. Replace Brake Pads and Rotors (if necessary)

Sub-steps:
1. Remove the caliper by unbolting the caliper bracket bolts.
2. Remove the old brake pads from the caliper bracket.
3. If rotors are to be replaced, remove the rotor by unbolting it from the hub.
4. Install new rotors, ensuring they are properly seated.
5. Insert new brake pads into the caliper bracket.
6. Reinstall the caliper over the new pads and torque the caliper bolts to manufacturer's specifications (usually around 25-35 ft-lbs).

5. Reassemble and Test

Sub-steps:
1. Reattach the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and fully tighten the lug nuts in a star pattern to the manufacturer's torque specification (usually around 100-110 ft-lbs).
3. Pump the brake pedal a few times to seat the pads.
4. Drive the vehicle at low speed to test the brakes and listen for any grinding noise.
