Wilwood High-Volume aluminium master cylinders have the highest fluid capacity of any integral reservoir design. With a total capacity of 242ml (8.2oz), there is at least 26% more fluid than most competitive brands. More fluid volume means cooler temperatures and additional insurance for extreme conditions where high pad wear can compromise fluid levels during long events. With 1-7/16" of piston travel, there is plenty of margin when used with large four or six piston callipers
