Wilwood High volume master cylinder.
3/4"Wilwood High-Volume aluminum master cylinders have the highest fluid capacity of any integral reservoir design. With a total capacity of 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 eventsAn internal slosh baffle guarantees a constant fluid supply to the bore chamber during hard cornering, acceleration, and braking. This unique baffle also eliminates aeration into the reservoir from return fluid that can occur during brake release and bleeding procedures.
