Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, caliper, flashlight.
Safety Warnings: Ensure vehicle is on a flat surface and securely supported by jack stands.

2. Remove Wheel

Loosen the lug nuts slightly with the lug wrench.
Lift the vehicle with the jack and secure it on jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect Brake Pads

Locate the brake caliper and remove it according to the manufacturer’s specifications.
Check the brake pads visually; if they are less than 1/8 inch thick, they need replacement.
Use a caliper to measure the remaining thickness of the brake pads accurately.

4. Replace Brake Pads (if necessary)

If pads are worn, remove the old pads by sliding them out of the caliper bracket.
Clean the caliper bracket and apply brake grease to the backing of the new pads.
Install the new brake pads into the caliper bracket, ensuring correct orientation.
Reattach the caliper and torque bolts to the manufacturer’s specifications.

5. Reassemble and Lower Vehicle

Place the wheel back on and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and tighten the lug nuts to the specified torque.
Repeat the process for the other side if necessary.
