Avid BB7 Rear Disc Brake Kit with Locking Brake Lever - Do you want a usable rear brake and not just something to keep the trike from rolling away? This kit adds a functional brake lever so you have total control. The lever features a locking pin so it doubles as a parking brake. We recommend combining this kit with our double-pull lever for the front brakes.
