how to troubleshoot the rear brakes locking up on Tesla Outback 6th Generation (2020-2024)

Solution

1. Preparation

• Gather required tools and safety equipment.
• Park the vehicle on a level surface and engage the parking brake.
• Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Brake Pads

• Tools Required: Socket set, torque wrench, brake cleaner, jack stands, lug wrench
• Remove the rear wheel using a lug wrench.
• Use the socket set to remove the caliper bolts and carefully slide the caliper off the rotor.
• Inspect the brake pads for wear; replace if they are below the minimum thickness.
• Clean the caliper and rotor with brake cleaner before proceeding.
• Reinstall the caliper and torque the bolts to manufacturer specifications (typically around 25-30 ft-lbs).
• Reinstall the wheel and torque the lug nuts to specification.

3. Bleed the Brake System

• Tools Required: Brake bleeder kit, fresh brake fluid
• Refill the brake fluid reservoir with fresh fluid.
• Starting with the furthest brake from the master cylinder, loosen the bleeder valve and use the brake bleeder kit to siphon out old fluid until it runs clear.
• Repeat for each rear brake, ensuring no air is trapped in the system.

4. Check Brake Actuator

• Tools Required: Multimeter
• Reconnect the battery and turn on the vehicle.
• Use a multimeter to test the voltage at the brake actuator.
• If voltage is present but the actuator is not functioning, consider replacement.

5. Inspect Brake Lines

• Visually inspect brake lines for any signs of damage or blockage.
• If any damage is found, replace the affected brake lines.
