why does my Genesis G70 make a grinding noise when I brake

Solution

1. Preparation

• Gather required tools and parts.
• Ensure the vehicle is parked on a level surface.
• Engage the parking brake and wear safety gloves and glasses.

2. Remove Wheel

• Use a jack to lift the vehicle and secure it on jack stands.
• Remove lug nuts with a socket wrench and take off the wheel.

3. Inspect Brake Components

• Brake Pads:
  • Check the thickness; replace if less than 3mm.
  • Look for uneven wear or cracking.
• Brake Rotors:
  • Measure rotor thickness with a micrometer.
  • Inspect for grooves or warping; resurface or replace if necessary.

4. Replace Brake Pads (if necessary)

• Remove the caliper bolts using a socket set.
• Carefully lift the caliper off the rotor; support it to avoid stress on the brake line.
• Remove old brake pads from the caliper bracket.
• Install new brake pads, ensuring they are correctly positioned.

5. Reassemble Components

• Reattach the caliper over the new brake pads.
• Tighten caliper bolts to the manufacturer’s specified torque (usually around 25-35 ft-lbs).
• Reinstall the wheel and hand-tighten lug nuts.

6. Finishing Up

• Lower the vehicle off the jack stands.
• Tighten lug nuts in a crisscross pattern to the manufacturer’s torque specification (usually 80-100 ft-lbs).
• Pump the brake pedal a few times to seat the new pads.
