Solution

1. Preparation

Gather necessary tools and parts.
Make sure the vehicle is parked on a level surface and engage the parking brake.
Wear safety glasses and gloves.

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.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Locate the brake caliper and remove the caliper mounting bolts using a socket set.
Carefully slide the caliper off the rotor and support it using a bungee cord (do not let it hang by the brake line).
Remove the old brake pads from the caliper bracket.
Measure the thickness of the new brake pads against the old ones to ensure they are adequate.
Install new brake pads into the caliper bracket.

4. Inspect and Resurface/Replace Rotors

Check the brake rotors for any deep grooves or scoring.
If necessary, remove the rotors by taking out the retaining screws and sliding them off the hub.
If the rotors are within permissible limits, you may choose to resurface them; otherwise, replace them with new rotors.

5. Reassemble Brake Components

Reinstall the caliper over the new brake pads and secure it with the caliper mounting bolts.
Tighten the caliper bolts to the manufacturer's torque specifications (usually around 20-25 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Carefully lower the vehicle back to the ground.
Tighten lug nuts to the manufacturer's specifications (typically 75-100 ft-lbs).
Pump the brake pedal several times to ensure proper brake pad seating.
