Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety glasses and gloves.

2. Remove Wheel

Loosen the lug nuts with a socket set.
Lift the vehicle using a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench.
Carefully lift the caliper off the rotor and support it with a bungee cord (do not stretch brake line).
Remove old brake pads from the caliper bracket.
Inspect the backing plates for wear; replace if necessary.
Install new brake pads ensuring they are properly seated.

4. Inspect and Resurface/Replace Rotors

Check the rotor surface for grooves or excessive wear.
If rotors are scored, consider resurfacing them if within specification; otherwise, replace them.
If resurfacing, utilize a brake lathe to ensure a smooth, even surface.

5. Reassemble Brake Components

Reattach the caliper over the new brake pads.
Torque the caliper bolts to the manufacturer's specifications (typically around 20-25 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Final Checks

Lower the vehicle from the jack stands.
Tighten the lug nuts to the specified torque (typically around 80-100 ft-lbs in a crisscross pattern).
Pump the brake pedal to ensure proper engagement before driving.
