Master Cylinders, Fluids and Controls:

Wilwood High-Volume Aluminum Master Cylinders represent the latest refinements in brake pressure actuation and fluid control. Each master cylinder is high pressure die-cast from high-grade aluminum, fully machined, and assembled with exclusive features only available from Wilwood. Wilwood High-Volume aluminum master cylinders have the highest fluid capacity of any integral reservoir design. With a total capacity of 8.2 ounces, 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 calipers. Most other brands of aluminum master cylinders are traditional sand castings. Sand castings have a rougher and less accurate finish than die-castings and are more prone to porosity and pitting when the bores are machined. Consequently, sand-cast cylinders must be fitted with a stainless steel sleeve to achieve a smooth bore finish. The sleeve not only inflates the price of the master cylinder, but it also retains heat longer causing higher operating temperatures inside the piston bore.
