Solution

1. Preparation

Tools Required: Socket set, torque wrench, jack, jack stands, brake cleaner, bungee cord, protective gloves, safety goggles.
Safety Warnings: Ensure the vehicle is on a flat surface and the parking brake is engaged. Allow brakes to cool before working on them.

2. Raise the Vehicle

Sub-steps:
1. Loosen the lug nuts on the wheel (do not remove).
2. Use the jack to lift the vehicle and secure it with jack stands.
3. Remove the lug nuts and take off the wheel to access the brake caliper.

3. Remove the Brake Caliper

Sub-steps:
1. Locate the caliper mounting bolts (usually two bolts).
2. Use the socket set to remove the caliper mounting bolts.
3. Carefully lift the caliper off the rotor and support it using a bungee cord (do not let it hang by the brake line).

4. Replace the Brake Pads

Sub-steps:
1. Remove the old brake pads from the caliper bracket.
2. Inspect the caliper bracket for any debris or damage and clean it with brake cleaner.
3. Install the new brake pads into the caliper bracket, ensuring proper alignment with the rotor.
4. Use a C-clamp or brake pad tool to compress the caliper piston back into the caliper body to accommodate the new pads.

5. Reinstall the Brake Caliper

Sub-steps:
1. Position the caliper over the new brake pads and rotor.
2. Reinstall the caliper mounting bolts and tighten them to the manufacturer’s specified torque (consult the service manual for exact torque specifications).
3. Repeat steps 2-5 for the other side if necessary.

6. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle back to the ground.
3. Tighten the lug nuts to the manufacturer’s specified torque.
4. Pump the brake pedal a few times to ensure the brake pads seat correctly against the rotors.
