Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Loosen the lug nuts on the front or rear wheel where brake pads will be replaced.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel by completely unscrewing the lug nuts.

3. Remove Brake Caliper

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

4. Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Compress the caliper piston using a brake caliper tool or C-clamp to make space for the new pads.
Insert new brake pads into the caliper bracket, ensuring they are correctly aligned.

5. Reinstall Brake Caliper

Position the caliper back over the new brake pads and rotor.
Reinstall the caliper mounting bolts and torque them to the manufacturer’s specifications (typically around 25-35 ft-lbs for Genesis G70).

6. Reassemble Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and torque the lug nuts to the manufacturer’s specifications (usually around 80-100 ft-lbs).

7. Final Checks

Press the brake pedal a few times to ensure proper seating of the brake pads.
Check for any leaks and ensure all components are secure.
