Solution

1. Preparation

Gather tools: socket set, torque wrench, brake pad spreader, and jack stands.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Lift the Vehicle

Sub-steps:
1. Loosen the lug nuts on the front or rear wheels (depending on which pads are being replaced).
2. Use a jack to lift the vehicle and secure it with jack stands.
3. Completely remove the lug nuts and take off the wheel.

3. Remove Brake Caliper

Sub-steps:
1. Locate the caliper mounting bolts and remove them using a socket wrench.
2. Gently slide the caliper off the brake rotor. Do not let it hang by the brake line; use a bungee cord or similar tool to secure it.

4. Replace Brake Pads

Sub-steps:
1. Remove the old brake pads from the caliper bracket.
2. Install new brake pads into the caliper bracket, ensuring they are positioned correctly.
3. Use a brake pad spreader tool to compress the caliper piston back into the housing to accommodate the new pads.

5. Reassemble and Test

Sub-steps:
1. Reattach the caliper over the new brake pads and tighten the mounting bolts to the manufacturer’s torque specifications (usually around 20-30 ft-lbs).
2. Reinstall the wheel and hand-tighten the lug nuts.
3. Lower the vehicle and fully tighten the lug nuts to the proper torque specification (usually around 76 ft-lbs).
