Return PolicyWilwood 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.

Customers commend the product for its quality, performance, and usability. The clutch master cylinder functions as expected, proving useful in various applications, including racing and off-road modifications. It fits perfectly in different setups and is ideal for both stock and racing clutches. Its ease of installation and adaptability make it a go-to choice in custom pedal assembly, even though some customers reported a slight difficulty with upper bolt installation. Its compatibility with Wilwood pedals was also noted. Most reviewers would buy this product again and recommend it for its good value and excellent functioning.

Arrived in usual speedy, Speedway manner. MC bench bled easily. But in my view, unless one is matching up to a Wilwood pedal, maybe not worth the headache. The upper bolt hole only allows 1/2' clearance before contact with mc bowl, so better have needle nose vise grips, a swivel, just the right size bolt, yoga-like agility, and a plan, to install oneself. And/or a friend to take position under the dash or the other side of firewall.

Have used other brands of master/clutch cylinders with failures in about a year. Purchased these cylinders hoping they would solve the problem. They did with outstanding results, have better petals for both brake and clutch. Will purchase slave cylinder as well in near future.

How can I determine if a master cylinder is a quick take up or not for low drag calipers? I am looking for a manual 4 disc quick take up master cylinder and can not find anything that says specifically if it is what I am looking for.
