Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, torque wrench, brake cleaner, and safety glasses.
Raise the vehicle using a jack and secure it on jack stands.
Remove the wheel to access the brake components.

2. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Carefully lift the caliper off the rotor without disconnecting the brake line.
Inspect the brake pads for wear; if they are below the manufacturer's minimum thickness, replace them.
- Sub-steps:
  - Remove the old brake pads from the caliper bracket.
  - Clean the caliper bracket with brake cleaner.
  - Install new brake pads, ensuring they are correctly positioned.
Reattach the caliper over the new pads and torque the bolts to manufacturer specifications (usually around 25-30 ft-lbs for Tesla).

3. Inspect and Replace Brake Rotors (if necessary)

If the brake rotors are scored or warped, they need to be replaced.
- Sub-steps:
  - Remove the caliper bracket if it hasn't been removed yet.
  - Unscrew the rotor retaining screws (if equipped) and slide the rotor off the hub.
  - Install the new rotor, ensuring it is seated properly.
  - Reattach the caliper bracket.

4. Reassemble and Bleed Brakes

Reattach the wheel and lower the vehicle.
If brake pads or rotors were replaced, bleed the brake lines to remove any air.
- Sub-steps:
  - Use a brake bleeder kit to bleed the brakes starting from the furthest caliper from the master cylinder.
  - Check the brake fluid level and top off as necessary.
