why does my Genesis G70 make a grinding noise when braking

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is parked on a flat surface, and engage the parking brake.
• Disconnect the battery for safety.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

• Sub-steps:
  • Remove the caliper bolts using a socket wrench.
  • Carefully slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
  • Remove the old brake pads from the caliper bracket.
  • Check the condition of the caliper slides for lubrication and wear.
  • Install new brake pads, ensuring they are correctly positioned in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

• Sub-steps:
  • Check the rotor surface for grooves or warping.
  • If warped, remove the rotor by unscrewing the retaining screws (if applicable).
  • Install new rotors, ensuring they are clean and free of grease.
  • Tighten rotor retaining screws to manufacturer specifications.

5. Reassemble and Bleed Brake System

• Sub-steps:
  • Reinstall the caliper over the new brake pads and tighten caliper bolts to the specified torque.
  • Reattach the wheel and lug nuts, tightening them in a star pattern.
  • Lower the vehicle and remove the jack stands.
  • Reconnect the battery.
  • Bleed the brake system to remove any air bubbles, ensuring firm brake pedal feel.
