Massimo T Boss 550/560 Rear Differential Solenoid

This is a rear differential solenoid for a Massimo T Boss 550 or Massimo T Boss 560. If you leave your parking brake on while driving, the brake will heat up. After a long enough time that heat can damage the solenoid and cause it to leak. This is the replacement solenoid. If this is what happened to you make sure to inspect your parking brake pads and calipers for damage and adjustment. Then make sure the parking brake is not engaged while driving or the same thing will happen.
