A Road Runner not only wants to run fast but also needs to brake that way, if necessary – and this can be done via a convenient Disc Brake System.
At first, King Hardeman intended to go with 11” Disc Brakes. But he quickly experienced that 11” rotors look very small. And that therefore, 13” discs would be the right choice. The Calipers were grinded smoothly and powder coated in body color.
As a result, the Brake System perfectly stuffs these one-off Boyd Coddington 19” Wheels (on the front axle) now.
