Wilwood GS Integral Master Cylinder - .700in Bore

Wilwood is known for making performance brake components, and their GS Compact Integral Master Cylinders are a solid example of that. This particular unit features a .700 inch bore, which is a common size for many custom builds or upgrades where you need precise control over your braking system. It’s a rebuildable design, meaning you can service it down the road if needed, which is a nice touch for a part like this.

The body is made from die-cast aluminum, which keeps the weight down, and it’s finished with an e-coat for protection against corrosion. Inside, you'll find a positive seal internal bellows cap that keeps contaminants out. Wilwood also refined the return spring and piston assembly to ensure it handles pressure well and releases completely and quickly after you let off the brake pedal. This attention to internal detail helps make sure your braking feels consistent and responsive.
