The Ford Ranger Light Truck Pin-Rail Disc Brake Spring - Firmly Compliant 830411
Brake system “feel” is influenced by numerous vehicle parameters. The Ford Ranger sought to improve brake system feel over current light truck disc-drum systems by increasing caliper stiffness and reducing system feedback. The Ranger caliper is suspended by a unique pin-rail spring which firmly attaches the caliper assembly to the steering knuckle, yet provides controlled compliance to reduce brake feedback. This paper describes the pin concept; its design and operation to achieve controlled caliper compliance.
