The Springfield Brake drops the two ordinary (and confusing) brake springs and replaces them with one central spring that applies the same force to each arm, requiring no additional adjustment. This makes assembly incredibly easy - just bolt it on and go. The brake arms are designed to maximize stiffness and save weight without adding excessive cost. By die-casting the arms and using shared tooling to make each side, the Springfield meets all of the original design goals, resulting in a very powerful and affordable brake.
