why is my Tesla Model S Original (2012-2020) making a grinding noise when braking

Solution

1. Preparation

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

2. Raise the Vehicle

• Use a jack to lift the vehicle and secure it with jack stands.
• Remove the appropriate wheel to access the brake components.

3. Inspect and Replace Brake Pads

• Inspection:
  • Remove the caliper bolts using a socket set.
  • Carefully slide the caliper off the rotor.
  • Inspect the brake pads for thickness; replace if below 3mm.
• Replacement:
  • Remove the old brake pads from the caliper bracket.
  • Install new brake pads, ensuring they are seated correctly.
  • Apply brake grease on the backing of the pads to reduce noise.

4. Inspect and Replace Rotors (if necessary)

• Inspection:
  • Check the rotor surface for scoring or warping.
  • Measure rotor thickness; replace if below minimum specifications.
• Replacement:
  • Remove the rotor by unscrewing the retaining screws (if applicable).
  • Clean the hub surface, then install the new rotor.
  • Reinstall caliper over the new rotor.

5. Reassemble and Lower the Vehicle

• Reattach the caliper with the bolts and torque to the manufacturer specifications.
• Reinstall the wheel and torque lug nuts to specification.
• Lower the vehicle back to the ground.
