why does my Tesla Model S Plaid/Refresh (2021-present) shake when I brake

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is on a level surface and the parking brake is engaged.
• Disconnect the battery to avoid any electrical issues during service.

2. Inspect and Replace Brake Rotors

• Sub-steps:
  • Remove the wheel using a lug wrench.
  • Use a caliper tool to remove the caliper and hang it securely (avoid strain on the brake line).
  • Remove the rotor by unscrewing the retaining screws (if applicable) and gently sliding it off the hub.
  • Inspection: Check for warping using a runout gauge. Replace if warped beyond specifications (typically 0.003 inches).
  • Install new rotors, ensuring they are clean and free from grease.
  • Reattach the caliper and wheel, then torque the lug nuts to manufacturer's specifications (around 129 lb-ft for Tesla Model S).

3. Inspect and Replace Brake Pads

• Sub-steps:
  • Remove the caliper as described above.
  • Check the brake pads for wear indicators. If they are less than 3 mm thick, replace them.
  • Remove old pads and clean caliper surfaces.
  • Install new pads, ensuring they are seated properly.
  • Reattach the caliper and wheel, then torque the lug nuts.

4. Suspension Inspection

• Sub-steps:
  • Visually inspect control arms, bushings, and strut mounts for wear or damage.
  • If any components are damaged, replace them according to manufacturer specifications.
  • Ensure all bolts are torqued to specified values.

5. Tire Inspection

• Sub-steps:
  • Check tire pressure and adjust to recommended settings.
  • Inspect tires for uneven wear or damage. Replace if necessary.
  • Balance and align tires as needed.
