Master Cylinders

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.

An 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.

Die-cast from high-grade aluminum
Heavy-duty internal piston springs provide fast retraction for immediate release and positive fluid transfer without the need for cumbersome external pushrod springs
Pedal feel is improved, piston retraction is guaranteed, fluid recovery is quicker and the bleeding process is simplified
Formed steel lids, heavyweight bail wires and bellows type gaskets keep the fluid in and the moisture out with correct pressure balancing during fluid displacement
1/8"-27 NPT fluid port

Wilwood™s specially formulated Hi-Temp° 570 Racing Brake Fluid has a minimum 570° F. dry boiling point of to withstand the severe heat requirements of automotive racing. Hi-Temp° 570™s low viscosity allows easy bleeding of your brake system, eliminating aeration of the brake fluid caused by foaming due to excessive pumping of the pedal.
Hi-Temp° 570 comes in convenient 12 ounce containers hermetically sealed to guarantee against unwanted absorption of moisture which can drastically lower the fluids boiling point (fluid from larger containers tends to become contaminated with moisture, lowering its boiling point and making it unsuitable for racing applications.

EXP 600 Plus is a highly refined blend developed for extreme performance under the high heat and extreme pressure of professional motorsports.EXP 600 Plus has tested to 626 degrees Fahrenheit with a wet boiling point of 417 degrees Fahrenheit. These numbers far exceed any DOT or SAE specifications.
It is true that racing fluids need to have high boiling points. It is also true that fluids need to have low moisture affinity to slow the natural absorption rate of water vapor. But the true test of any fluid is how well it resists aeration and compressibility after it has been heated and pressure cycled a few hundred times. The real test is at the track. EXP has been proven to maintain firm pedal feel and quick response, long after others have failed.
