Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, brake caliper tool or C-clamp, torque wrench, brake cleaner, and a wire brush.
Park the vehicle on a flat surface, engage the parking brake, and turn off the ignition.
Loosen the lug nuts on the wheel where brake pads will be replaced, but do not remove them completely.

2. Lifting the Vehicle

Use the jack to lift the vehicle and place jack stands securely under the vehicle's frame.
Remove the lug nuts completely and take off the wheel.

3. Remove the Brake Caliper

Locate the caliper mounting bolts and use a socket wrench to remove them.
Carefully slide the caliper off the brake rotor. Support the caliper using a bungee cord or rope to avoid stressing the brake line.

4. Remove Old Brake Pads

Slide the old brake pads out of their slots in the caliper bracket.
Inspect the brake caliper bracket for rust or corrosion, cleaning as necessary with a wire brush.

5. Compress the Caliper Piston

Use a brake caliper tool or C-clamp to compress the caliper piston back into the caliper housing. This is necessary to accommodate the new, thicker brake pads.
Ensure the brake fluid reservoir cap is removed to allow fluid to return without causing overflow.

6. Install New Brake Pads

Apply brake lubricant to the backs of the new brake pads to reduce noise and prevent sticking.
Slide the new brake pads into the caliper bracket in the same position as the old pads.

7. Reattach the Brake Caliper

Position the caliper over the new pads and align it with the mounting bracket.
Reinstall and tighten the caliper mounting bolts to the manufacturer’s specified torque (usually around 25-30 ft-lbs).

8. Reassemble the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands using the jack.
Once on the ground, use a torque wrench to tighten the lug nuts to the manufacturer’s specified torque (usually around 76 ft-lbs).

9. Final Checks

Replace the brake fluid reservoir cap.
Pump the brake pedal several times to ensure the pads seat correctly and the brakes function properly before driving.
