Wilwood High-Volume Aluminum Master Cylinder and 12 oz. Fluid

Master Cylinder

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

Brake Fluid

Wilwood's specially formulated Hi-Temp 570° Racing Brake Fluid has a minimum 570 degree dry boiling point 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.

This high temp brake fluid comes in a convenient 12 ounce container 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).

• Dry Boiling Point: 573° F
• Wet Boiling Point: 313° F
