Solution

1. Preparation

Tools Required: Socket set, torque wrench, brake caliper tool, jack and jack stands, wheel chocks, brake cleaner, and safety goggles.
Park the vehicle on a flat surface and engage the parking brake.
Place wheel chocks behind the rear wheels to prevent movement.

2. Remove Wheel

Loosen the lug nuts on the wheel using a socket wrench.
Use a jack to lift the vehicle and secure with jack stands.
Remove the lug nuts completely and take off the wheel to expose the brake assembly.

3. Remove Brake Caliper

Locate and remove the caliper bolts using the appropriate socket size.
Gently slide the caliper off the rotor. Do not let it hang by the brake line; support it with a bungee cord or similar.

4. Remove Old Brake Pads

Slide the old brake pads out of the caliper bracket.
Inspect the caliper bracket for any debris or corrosion and clean if necessary.

5. Prepare New Brake Pads

Compare new brake pads with old ones to ensure proper fit.
Apply brake grease to the back of the new pads to prevent squeaking.

6. Install New Brake Pads

Slide the new brake pads into the caliper bracket.
Ensure they are seated properly and aligned with the rotor.

7. Reinstall Brake Caliper

Use a brake caliper tool to compress the caliper piston back into the caliper housing to accommodate the new pads.
Reinstall the caliper over the new pads and secure it by tightening the caliper bolts to the manufacturer's specified torque (usually around 79 ft-lbs).

8. Reassemble Wheel

Place the wheel back on the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and then fully tighten the lug nuts in a crisscross pattern to the appropriate torque specification (usually around 76 ft-lbs).

9. Final Checks

Pump the brake pedal a few times to ensure proper engagement of the brake pads.
Check the brake fluid level in the master cylinder and top off if necessary.
