Wilwood Independent Reservoir Master Cylinder ~ For use with dual/independent rear handbrake calipers ~ We modify Model no. 260-10372 to fit into our compact handbrake structures. Non-thrust bearing handbrakes use re-threaded and shortened rods. Thrust bearing setups use slightly shortened rods. This means that masters purchased here wont always work with other brands of handbrakes. ~ 3/4" bore (0.75") ~ 1/8-27 NPT outlet port (tapered pipe thread, NOT COMPATIBLE WITH BANJO FITTINGS). ~ Includes a remote reservoir mounting kit. ~ We offer a universal line & fitting kit for this inline master & dual rear calipers ~ which offers a great deal of convenience versus sourcing the list of things needed from multiple sellers.
