Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Lug wrench
- Socket set
- C-clamp or brake caliper tool
- Brake cleaner
- Torque wrench
- Safety goggles and gloves
Sub-steps:
1. Park the vehicle on a level surface and engage the parking brake.
2. Wear safety goggles and gloves for protection.
3. Loosen the lug nuts on the wheel where you will replace the brake pads, but do not remove them yet.

2. Raise the Vehicle

Sub-steps:
1. Use the jack to lift the front or rear of the vehicle, depending on which brake pads are being replaced.
2. Secure the vehicle with jack stands to ensure stability.
3. 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. Carefully slide the caliper off the brake rotor, taking care not to strain the brake line.
3. Suspend the caliper using a bungee cord or rope to prevent it from hanging on the brake line.

4. Replace Brake Pads

Sub-steps:
1. Remove the old brake pads by sliding them out of the caliper bracket.
2. Clean the caliper bracket and rotor surface with brake cleaner to remove dust and debris.
3. Insert the new brake pads into the caliper bracket, ensuring they are seated properly.

5. Reassemble Brake Components

Sub-steps:
1. Use a C-clamp or brake caliper tool to compress the caliper piston back into the caliper housing for clearance.
2. Carefully position the caliper back over the new brake pads and rotor.
3. Reinstall the caliper mounting bolts and tighten them to the manufacturer's specified torque.

6. Final Steps

Sub-steps:
1. Reattach the wheel and hand-tighten the lug nuts.
2. Lower the vehicle from the jack stands using the jack.
3. Once on the ground, torque the lug nuts to the manufacturer’s specifications.
4. Repeat the process for the other side if necessary.
