Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Engage the parking brake and place wheel chocks behind the rear wheels.
Tools Required: Jack, jack stands, lug wrench, brake cleaner, torque wrench, caliper tool (if needed).

2. Remove Wheels

Loosen lug nuts slightly while the vehicle is on the ground.
Use a jack to lift the front of the vehicle and secure with jack stands.
Remove the lug nuts completely and take off the front wheels.

3. Inspect and Replace Brake Pads

Remove the brake caliper bolts using the appropriate socket.
Carefully slide the caliper off the rotor and support it without straining the brake line.
Remove the old brake pads from the caliper bracket.
Clean the caliper bracket and rotor with brake cleaner.
Install new brake pads into the bracket, ensuring they are seated properly.
Reinstall the caliper over the new pads and torque the caliper bolts to manufacturer specifications (typically around 25-30 ft-lbs).

4. Check and Replace Brake Rotors (if necessary)

If rotors are worn, remove them from the hub.
If replacing, install new rotors by aligning them with the hub and securing with the lug nuts (do not fully tighten yet).
If resurfacing, ensure they meet manufacturer specifications.

5. Reassemble and Test

Reinstall the wheels and hand-tighten the lug nuts.
Lower the vehicle back to the ground and then torque the lug nuts to the specified value (often 100-110 ft-lbs for the Model 3).
Pump the brake pedal to ensure proper seating of the brake pads.
Test drive the vehicle to check for noise and confirm brake performance.
