Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake pad spreader, anti-seize lubricant, clean rags
Park the vehicle on a level surface and engage the parking brake.
Disconnect the vehicle from any power source and ensure the vehicle is in "Park" mode.

2. Raise the Vehicle

Use a lug wrench to loosen the lug nuts on the wheels where brake pads will be replaced.
Lift the vehicle using a jack and securely place jack stands under the vehicle.
Remove the loosened lug nuts and take off the wheel.

3. Remove Old Brake Pads

Locate the brake caliper and remove the bolts securing it using the appropriate socket.
Carefully slide the caliper off the rotor and suspend it using a bungee cord to avoid straining the brake line.
Remove the old brake pads from the caliper bracket. Note the arrangement for reinstallation.

4. Compress the Caliper Piston

Use a brake pad spreader or C-clamp to compress the caliper piston back into the caliper housing. This allows space for the new, thicker brake pads.
Ensure the brake fluid reservoir cap is loosened to prevent pressure buildup.

5. Install New Brake Pads

Apply anti-seize lubricant on the back of the new brake pads to minimize noise and ensure smooth operation.
Place the new brake pads into the caliper bracket in the same orientation as the old ones.
Reinstall the caliper over the new brake pads and secure it with the previously removed bolts. Torque the bolts to the manufacturer’s specifications.

6. Reassemble and Lower the Vehicle

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and remove the jack.
Torque the lug nuts to the manufacturer's specifications in a crisscross pattern.

7. Final Checks

Reconnect the vehicle to power if necessary and check the brake fluid level, topping off if needed.
Test the brake pedal to ensure proper feel before taking the vehicle for a drive.
