Arlen Ness Big Brake Kit Install

Big Brake Check

When it comes to braking surface area, bigger is better, right? The Big Brake Kit from Arlen Ness replaces the stock unit with a massive 15-inch rotor. It utilizes the stock lines and relocates the rotors with a billet-aluminum-adapting bracket. We enlisted the help of IMZZ Elite to install the kit on our 2015 Dyna Low Rider, but installation is as easy as changing a set of rotors and can be done quickly and easily with hand tools in a garage.
