  • Multiple feed brake caliper
    Patent number: 6986410
    Abstract: A disc brake caliper for conversion of a motorcycle with a linked braking system to a trike integrates two or more separate sets of opposed braking cylinders and pads within a single housing. Braking cylinder sets are not connected to other braking cylinder sets within the housing. Each set of braking cylinders is connected to and actuated independently by a different master cylinder. At least two braking cylinder sets within a housing have different diameters, the diameters of each set being chosen to produce a desired amount of braking pressure in response to an expected amount of hydraulic pressure from a master cylinder actuating the set. Both the diameter of each braking cylinder set and ratio of diameters between different braking cylinder sets are chosen to produce the optimum rear wheel braking pressure allocation for a given braking control system and vehicle configuration with no changes to the master cylinders or the front wheel braking system.
