Wilwood Compact Remote Aluminum Master Cylinder - .700in Bore

This Wilwood master cylinder kit includes the .700 inch bore aluminum master cylinder itself. It's designed for custom builds where space is tight, like club sport racers or small open-wheel cars. This part is a solid choice when you need a compact master cylinder that still offers a full 1.4 inches of stroke, which is helpful for short pedal ratios or smaller brake calipers.

The aluminum construction keeps it lightweight, and it's built to work with either a detachable or a remote fill reservoir, giving you flexibility in how you set up your system. Wilwood offers this in a few different bore sizes, but the .700 inch option is a popular middle ground for many custom brake setups and hydraulic clutch applications.
