Wilwood Combination Master Cylinder Repair Set for a 5/8-inch Bore, Reuses Existing Pushrod

This five-eighths-inch repair kit services the internal piston and sealing components of the matching Combination Remote master. A spring, dust boot, retaining ring and reservoir-interface seals support the rebuild without replacing the cylinder body. Wilwood Engineering, the Camarillo, California disc brake manufacturer founded by Bill Wood in 1977, designs and builds systems for specialized, motorsport and street-performance applications. The product range covers brake lines, valves, fittings, calipers, master cylinders and rotors. A replacement component must preserve the intended relationship between the system's hydraulic and mechanical parts.

Fitment & Compatibility

Match master 260-3372 and its five-eighths-inch bore. The installation sheet reuses the existing pushrod and retaining washer, so inspect those parts before dismantling the assembly. Follow the bore-specific rebuild and bleeding instructions, and do not substitute this kit for a shorter Compact Remote family solely because the bore matches.
