Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Safety warning: Wear safety glasses and gloves.

2. Raise the Vehicle

Using a jack, lift the vehicle and secure it with jack stands.
Remove the wheel to access the brake components.

3. Remove the Brake Caliper

Using a socket set, remove the caliper mounting bolts.
Carefully slide the caliper off the rotor; do not let it dangle by the brake line.
Suspend the caliper using a bungee cord or rope to avoid stress on the brake line.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Inspect the brake rotor for wear; replace if necessary.
Install new brake pads in the caliper bracket, ensuring they are properly aligned.

5. Reassemble the Brake Caliper

Compress the caliper piston using a C-clamp or brake caliper tool to fit over the new pads.
Reinstall the caliper onto the rotor and tighten the mounting bolts to manufacturer specifications.

6. Reinstall Wheel and Lower the Vehicle

Place the wheel back on, hand-tighten the lug nuts, and lower the vehicle.
Tighten the lug nuts to the specified torque value in a crisscross pattern.
