Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the 12V battery to prevent electrical issues while working on the brakes.

2. Remove Wheel

Loosen the lug nuts using a socket wrench.
Raise the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Remove Brake Caliper

Locate the caliper mounting bolts; typically require a socket or wrench.
Remove the caliper bolts and carefully slide the caliper off the rotor.
Use a bungee cord or rope to hang the caliper, avoiding strain on the brake line.

4. Replace Brake Pads

Remove old brake pads from the caliper bracket.
Compress the caliper piston using a brake caliper tool to make room for the new pads.
Install new brake pads in the caliper bracket, ensuring proper orientation.

5. Reinstall Caliper and Wheel

Slide the caliper back over the new brake pads.
Reinstall and torque the caliper mounting bolts to the manufacturer specifications.
Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value.

6. Final Steps
