how to fix the Tesla Model Y Current (2020-present) that shakes during braking?

Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a flat surface and engage the parking brake.
• Disconnect the 12V battery to prevent any electrical issues while working.

2. Inspect and Replace Brake Components

2.1 Check Brake Pads

• Remove the wheel using a socket set.
• Inspect the brake pads for wear; replace if they are below the minimum thickness (usually below 3mm).
• Tools Required: Socket set, brake pad gauge.

2.2 Check Brake Rotors

• Use a dial indicator to measure rotor runout; maximum acceptable runout is generally 0.002 inches.
• If warping is detected, either resurface the rotors or replace them.
• Tools Required: Dial indicator, torque wrench.

3. Suspension and Steering Inspection

• Inspect control arms, tie rods, and other suspension components for any signs of wear or damage.
• Replace any worn or damaged components with OEM parts.
• Tools Required: Socket set, pry bar.

4. Wheel Alignment

• After replacing any worn brake or suspension components, perform a four-wheel alignment.
• Adjust camber, caster, and toe settings to manufacturer specifications.
• Tools Required: Alignment machine.

5. Reassemble and Test

• Reinstall the wheel and torque the lug nuts to manufacturer specifications (typically 100-120 ft-lbs).
• Reconnect the battery and perform a test drive to ensure the issue is resolved.
• Tools Required: Torque wrench.
