Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Remove Wheel

Loosen lug nuts using a socket set.
Use a jack to lift the vehicle and secure with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Locate the brake caliper and remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the brake pads and suspension components.
Remove the old brake pads and check for wear indicators. If pads are worn below the manufacturer’s specifications, replace them.
Install new brake pads, ensuring they are correctly aligned and seated.

4. Inspect and Replace Brake Rotors

Check the rotor surface for grooves or warping. If damaged, replace the rotors by removing the retaining screws and sliding them off the hub.
Install new rotors, ensuring they are properly aligned and secured.

5. Reassemble Brake Components

Reattach the brake caliper over the new pads and rotor, tightening bolts to manufacturer torque specifications (typically 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (typically 80-100 ft-lbs).
