Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Wear safety gloves and goggles.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect: Check the thickness of the brake pads. If they are less than 1/8 inch, they need replacing.
Remove: Unbolt the caliper using a socket set and slide it off the rotor.
Replace: Slide the new brake pads into the caliper bracket. Ensure they are oriented correctly.

4. Inspect and Resurface/Replace Rotors

Inspect: Check the rotors for grooves or scoring. If damaged, they should be resurfaced or replaced.
Remove: Unbolt the rotor from the hub if replacement is necessary.
Resurface: If resurfacing, take them to a machine shop or use a brake lathe if available.

5. Reassemble Components

Reattach the rotor (if removed) and ensure it is torqued to manufacturer specifications.
Reinstall the caliper over the new brake pads.
Torque the caliper bolts to manufacturer specifications.
Reinstall the wheel and torque the lug nuts in a star pattern.

6. Finish Up

Lower the vehicle and remove the jack stands.
Tighten the lug nuts fully.
Pump the brake pedal to seat the pads before driving.
