REAR BRAKE MASTER CYLINDERS FOR BIG TWIN & SPORTSTER
Availability: In stock
Part #: 45411
Weight: 0.06
CNC machined from aircraft quality aluminum alloy. The bore is 5/8" diameter. The smaller piston diameter produces more pressure and increases stopping power. This master cylinder is designed to work in conjunction with the dual piston GMA brake calipers. Will also work with Grimeca and other aftermarket dual piston calipers.

Note: Early master cylinders were used in conjunction with the OEM rebuild kit 42374-82A and required shortening the plunger rod. Late master cylinders use a redesigned rebuild kit and do not require shortening the plunger rod. Verify the correct kit needed before ordering.
