Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Remove Wheel

Loosen wheel lug nuts using a lug wrench.
Lift the vehicle with a jack and secure it on jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Sub-steps:
- Inspect the thickness of the brake pads. If they are below 3mm, they need replacement.
- Remove the caliper bolts using a socket set and lift the caliper off the rotor.
- Slide out the old brake pads from the caliper bracket.
- Clean the caliper bracket and check for rust or debris.
- Install new brake pads, ensuring they are seated correctly.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
- Check the rotor surface for grooves or warping. If damaged, they should be replaced.
- Remove the caliper bracket if needed using the appropriate socket.
- Remove the rotor by unscrewing any retaining screws, if applicable.
- Install new rotors, ensuring they are properly aligned with the hub.

5. Reassemble and Test

Reinstall the caliper over the new pads or rotors.
Tighten caliper bolts to manufacturer specifications (usually around 25-35 ft-lbs).
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value (usually 100-120 ft-lbs).
Pump the brake pedal to seat the pads before driving.
