Product details
The three-quarter-inch GS Integral master carries its fluid reservoir directly on the cylinder body. Its bore and 1.25-inch stroke provide the specified 0.55-cubic-inch output, while the black finish and bellows-seal cap protect the exterior and fluid opening. Wilwood Engineering's disc brake systems bring together calipers, rotors, valves, master cylinders, fittings and brake lines. Founded by Bill Wood in 1977 and based in Camarillo, California, the company designs and manufactures products for motorsport, street-performance and specialized applications. The installed system determines which individual component is appropriate.

Fitment & Compatibility
Check both displacement and reservoir reserve for the installed hydraulic circuit. Use the 3/8-24 female inverted-flare outlet, 5/16-24 rod and 2.25-inch flange as distinct connection requirements. If the system places the master below the brakes, assess the appropriate residual-pressure arrangement separately.
