- Brake pad spreader tool
- Socket set
- Brake cleaner
- Brake lubricant
Sub-steps:
1. Park the Tesla on a flat surface and engage the parking brake.
2. Disconnect the 12V battery to ensure safety while working on the braking system.
3. Gather all necessary tools and parts for the replacement.

2. Raise the Vehicle

Sub-steps:
1. Loosen the lug nuts slightly with a lug wrench before raising the vehicle.
2. Use the jack to lift the front or rear of the vehicle and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Remove Old Brake Pads

Sub-steps:
1. Locate the brake caliper and remove the bolts using a socket set.
2. Carefully slide the caliper off the rotor and support it using a bungee cord or similar device to avoid straining the brake line.
3. Remove the old brake pads from the caliper bracket.

4. Reinstall the caliper over the new brake pads and secure it with the bolts.

5. Reassemble and Test

Sub-steps:
1. Reattach the wheel and hand-tighten the lug nuts.
2. Lower the vehicle from the jack stands and then fully tighten the lug nuts in a criss-cross pattern to the manufacturer's torque specifications.
3. Reconnect the 12V battery.
4. Pump the brake pedal several times to restore brake pressure before driving.
