why does my Genesis G70 have a grinding noise when braking

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Ensure the vehicle is parked on a level surface and the parking brake is engaged.
• Wear safety gloves and goggles.

2. Remove Wheel

• Use a lug wrench to loosen the wheel lug nuts.
• Lift the vehicle using a jack and secure it with jack stands.
• Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

• Inspection:
  • Check the brake pads for wear; replace if less than 3 mm thick.
  • Look for uneven wear patterns.
• Replacement:
  • Remove the caliper bolts using a socket set.
  • Slide the caliper off the rotor and support it without straining the brake line.
  • Remove the old brake pads from the caliper bracket.
  • Install new brake pads, ensuring they are properly seated.
  • Reinstall the caliper over the new pads and tighten the caliper bolts to the manufacturer's torque specifications (typically 25-35 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

• Check the rotors for any visible damage or warping.
• If replacement is required, remove the caliper bracket.
• Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
• Install new rotors, ensuring they are clean and free from debris.
• Reinstall the caliper bracket and tighten bolts to the specified torque.

5. Reassemble and Test

• Reinstall the wheel and hand-tighten the lug nuts.
• Lower the vehicle and torque the lug nuts to the specified value (typically 80-100 ft-lbs).
• Pump the brake pedal to ensure the pads seat properly against the rotors.
• Check the brake fluid level and top off if necessary.
