Performance Machine Brake Master Cylinders

6 products — part of all Brake Master Cylinders

Performance Machine brake master cylinders are machined from billet aluminium to tighter tolerances than factory units, with bore diameters and piston displacements selected to complement the larger-diameter PM brake rotors and multi-piston calipers they are designed to work alongside. On a Harley-Davidson with upgraded braking hardware, the master cylinder is the component that determines how force translates from lever or pedal to caliper, and fitting a master cylinder that matches the rest of the system produces a progressive, consistent feel that OEM masters often cannot deliver with performance calipers. PM master cylinders are available for both hand-lever and foot-pedal applications, finished in polished or contrast-cut black to coordinate with the rest of the PM brake assembly. Iron City Motorcycles in Leeds stocks Performance Machine braking components so that customers building a full PM brake upgrade can source every piece of the system through one specialist.
