Brake and clutch master cylinders should be rebuilt before they fail! Top racing teams rebuild master cylinders at least once each season for best reliability.
This rebuild kit is designed specifically to fit the OBP 7/10 Bore FC-Series Compact Master Cylinder (Part No. OBP-FC-700). The kit includes a complete piston and spring assembly with all rubber seals already installed. You get a complete set of new internals, already assembled and ready for installation. Just lubricate the seals and drop it in! Sold individually; one kit is enough to rebuild one master cylinder.
Note: This rebuild kit fits obp Motorsport brand compact master cylinder only. It does not fit obp full-size master cylinders, or any other brand.
OBP casts the bore size directly into the side of the master cylinder for positive identification. The 7/10 inch bore is typically shown as .70 but may be shown as 7/10.
