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 goggles and gloves.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket wrench.
2. Carefully slide the caliper off the brake pads without stretching the brake line.
3. Check the brake pads for wear; if they are less than 1/8 inch thick, replace them.
4. If replacing, install new brake pads by sliding them into the caliper bracket.
5. Apply brake grease to the backing of the new pads to prevent noise.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check the rotor surface for grooves or scoring.
2. If damaged, remove the rotor by unscrewing the retaining screws (if equipped) and sliding it off the hub.
3. Install new rotors by aligning them with the hub and securing them with screws.
4. Ensure the rotor surface is clean and free of debris.

5. Reassemble and Test

Sub-steps:
1. Reattach the caliper over the new pads and torque the caliper bolts to manufacturer specifications.
2. Reinstall the wheel and hand-tighten the lug nuts.
3. Lower the vehicle and torque the lug nuts to the manufacturer’s specification using a torque wrench.
4. Pump the brake pedal several times to restore brake pressure.
