Wilwood GS Compact Master Cylinder Bore

The Wilwood GS Compact Master Cylinder line is a rebuildable brake and clutch master cylinder for custom, hot rod, race, and universal hydraulic applications. Wilwood designed it as a lightweight, space-saving unit. It is a good fit where a standard master cylinder is too large. Select the bore size that suits your hydraulic setup.

Key Features:

• Rebuildable design: The body is high-pressure die-cast aluminum, so the cylinder can be serviced rather than replaced.
• Protective E-coat finish: The black finish helps resist corrosion.
• Positive pressure control: A refined return spring and piston assembly gives consistent pedal feel and a quick, complete release.
• Integral and remote options: Integral versions have a built-in reservoir with a positive-seal internal bellows cap. Remote versions have a standard 7/16-20 threaded inlet for a separate reservoir. They suit inline handbrake setups and dual-caliper layouts.
• Single outlet: The outlet is a 3/8-24 inverted flare female fitting.
• Multiple bore sizes: A range of bore sizes lets you match the cylinder to your caliper and pedal ratio.
• Made in the USA: Wilwood builds the cylinders in the United States.

Wilwood is known for high-performance disc brake components. The GS Compact series gives builders a compact, serviceable master cylinder for brake or clutch use.
