Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety goggles.
Safety Warnings: Ensure the vehicle is on a flat surface and the parking brake is engaged before lifting the vehicle. Always wear safety goggles when working on brakes.

2. Lift the Vehicle

Sub-steps:
1. Use the lug wrench to loosen the lug nuts on the wheel where brake pads will be replaced.
2. Lift the vehicle using the jack and secure it with jack stands.
3. Remove the loosened lug nuts and take off the wheel.

3. Remove Brake Caliper

Sub-steps:
1. Locate the caliper mounting bolts and remove them using the socket set.
2. Carefully slide the caliper off the brake rotor. Do not let it hang by the brake line; instead, support it with a bungee cord or similar.

4. Remove Old Brake Pads

Sub-steps:
1. Slide the old brake pads out of the caliper bracket.
2. Inspect the caliper and bracket for wear or damage.

5. Install New Brake Pads

Sub-steps:
1. Apply brake grease to the backing plates of the new brake pads (if required).
2. Position the new brake pads into the caliper bracket.

6. Reinstall Brake Caliper

Sub-steps:
1. Carefully compress the caliper piston using a brake caliper tool or a C-clamp to allow for new pad thickness.
2. Reposition the caliper over the new pads and secure it with the mounting bolts. Torque the bolts to the manufacturer’s specifications.

7. Reassemble Wheel and Lower Vehicle

Sub-steps:
1. Place the wheel back onto the hub and hand tighten the lug nuts.
2. Lower the vehicle off the jack stands and then torque the lug nuts to the manufacturer's specifications.
