Please Note:
Carlisle Industrial Brake does not recommend the Hoppy or TAP breakaway kit numbers 20099 or 20400, or any kit equipped with a built-in battery meter and LED test lights for use in conjunction with trailers equipped with disc brakes. There is a possibility of the brakes not releasing completely, resulting in damage to the brake system.
