Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Use wheel chocks to prevent vehicle movement.

2. Remove Wheel

Loosen lug nuts slightly while the wheel 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 Pads

Inspect Brake Pads:
- Remove the caliper bolts using a socket.
- Slide the caliper off the rotor.
- Check the pads for wear; if less than 1/8" remaining, replace.
Replace Brake Pads:
- Remove the old pads from the caliper bracket.
- Install new pads, ensuring they are seated properly.
- Apply brake grease to the backing of the pads to reduce noise.

4. Inspect and Replace Brake Rotors

Inspect Rotors:
- Check the rotor surface for scoring or deep grooves.
- If damaged, they must be resurfaced or replaced.
Replace Rotors:
- Remove the caliper bracket if necessary (remove bolts).
- Slide the rotor off the hub.
- Install the new rotor, ensuring it is flush against the hub.

5. Reassemble Braking Components

Reattach the caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer’s specified torque (usually around 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test

Lower the vehicle and remove wheel chocks.
Torque the lug nuts to manufacturer specifications (usually around 76-80 ft-lbs).
Pump the brake pedal to seat the pads before driving.
