Wilwood High Volume Aluminum Master Cylinder - 1in Bore

This Wilwood master cylinder kit includes the high-volume aluminum master cylinder with an integral reservoir, formed steel lids, and bellows-type gaskets. It's built with a high-pressure die-cast aluminum body for strength and a 1-inch bore size, making it suitable for various braking setups. The integral reservoir holds 8.2 ounces of fluid, which is notably more than many other designs, giving you a larger margin for error, especially when paired with larger caliper pistons. This extra fluid capacity and the heavy-duty internal springs that ensure fast piston retraction are key to maintaining consistent braking performance.

Designed with common flange or side mounting dimensions, this master cylinder also features a 1/8-27 NPT outlet port for easy connection to your brake lines. The piston travel is 1-7/16 inches, providing ample room for caliper piston extension. The steel lids are sealed with bellows-type gaskets to help keep moisture out of the brake fluid, contributing to the longevity of your braking system.
