High Volume Aluminum 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.
Features
Each master cylinder is high pressure die-cast from high-grade aluminum, fully machined and assembled with exclusive features only available from Wilwood.
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.
Wilwood master cylinders use common dimensions for either flange or side mounting with 1/8-27 NPT fluid ports for easy interchange with all other racing master cylinders.
SIZING RECOMMENDATIONS
1" Master Cylinder Bore - Front Brakes
7/8" Master Cylinder Bore - Rear Brakes
3/4" Master Cylinder Bore - Clutch
Note: Larger master cylinder bores provide LESS pressure at the caliper
