Product details
This black Compact Tandem master keeps both fluid chambers within a shorter integral-reservoir housing. A seven-eighths-inch bore and included threaded pushrod suit an appropriately matched manual brake layout, with pressure-port choices on both sides. 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
Check the slotted 3.22–3.40-inch flange and the space needed by the complete rod-equipped assembly. The cylinder must reach its full 1.10-inch stroke before an external pedal stop. Fit the supplied line adapters to double-flared tubing, plug unused outlets and select any combination valve separately.
