Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, brake pad spreader, torque wrench, socket set, ratchet, and safety glasses.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the 12V battery to prevent any electrical issues while working on the braking system.

2. Lift the Vehicle

Loosen the lug nuts on the front or rear wheels slightly.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheels.

3. Remove Old Brake Pads

Locate the brake caliper; remove the caliper bolts using the socket set.
Carefully slide the caliper off the brake rotor and rest it on a suspension component (do not hang by the brake line).
Remove the old brake pads from the caliper bracket.

4. Install New Brake Pads

Apply brake grease to the backing of the new brake pads to prevent squealing.
Insert the new brake pads into the caliper bracket, ensuring they seat correctly.
Use a brake pad spreader to compress the caliper piston back into the caliper housing, allowing space for the new pads.

5. Reassemble Brake Components

Slide the caliper back over the new brake pads and align it with the bracket.
Reinstall and torque the caliper bolts to the manufacturer’s specifications (typically around 25-30 ft-lbs).
Reinstall the wheels and hand-tighten the lug nuts.

6. Lower Vehicle and Finalize

Carefully remove the jack stands and lower the vehicle back to the ground.
Tighten the lug nuts to the specified torque (usually 100-120 ft-lbs) in a crisscross pattern.
Reconnect the 12V battery.
