Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Use jack stands and a jack to lift the vehicle safely.

2. Remove Wheel

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

3. Remove Brake Caliper

Locate the caliper bolts (typically two bolts).
Use a socket set to remove the caliper bolts.
Carefully slide the caliper off the brake pads and suspend it using a bungee cord or wire to prevent strain on the brake line.

4. Inspect and Replace Brake Pads

Check the thickness of the existing brake pads; if they are below 1/4 inch, they should be replaced.
Remove the old pads from the caliper bracket.
Install new brake pads into the bracket, ensuring they are seated correctly.

5. Reassemble Brake Components

Reinstall the caliper over the new pads.
Tighten the caliper bolts to the manufacturer’s specified torque value (typically 20-25 ft-lbs).
Reattach the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle from the jack stands using the jack.
Tighten the lug nuts to the manufacturer’s specified torque value (usually 75-90 ft-lbs).
Pump the brake pedal a few times to ensure proper pad seating.
