Wilwood High Volume Aluminum Master Cylinder - 7/8in Bore

Wilwood is known for making performance brake components, and this High Volume Aluminum Master Cylinder is a solid example of their work. This master cylinder features a high-pressure die-cast aluminum body and has the largest fluid capacity in its class, holding 8.2 ounces. That extra fluid volume, at least 26% more than other brands, helps ensure consistent braking performance, especially when you're running larger calipers that require more fluid displacement. The 1-7/16 inches of piston travel gives you a good margin for error, and heavy-duty internal springs make sure the piston retracts quickly after you release the brake pedal. It also uses formed steel lids with bellows gaskets to keep moisture out, and it has common mounting dimensions with a 1/8-27 NPT outlet port for easy installation.
