This oversized bore Teraflex Brake Master Cylinder is ideal for use with Teraflex's Big Brake Kit (part# TER4303400) or other aftermarket big brake kits.

    Premium Quality Construction. Cast from premium quality aluminum for strength, this Teraflex Master Brake Cylinder features factory style connections with high-quality EPDM rubber compound seals.
