Each master cylinder is configured with full separation between the front and rear reservoir chambers and fluid outlets. There is a pressure access on both sides of the piston bore for right or left hand plumbing based on mount location. A total piston stroke of 1.10” is distributed at a 2:1 volume ratio between the primary and secondary chambers.

Customers appreciate the product for its high functionality and efficient performance. They found it the best choice for 4-wheel disc brakes, with key features such as a primary circuit with a 2:1 ratio contributing to its superior performance. Regardless of vehicle type - from 1940 Pontiac streetrods to s10 drag cars - the product provided an excellent solution for brake system upgrades. Even for customers with big calipers, any minor issues encountered were attributed to their application, not the product quality. The product, deemed 'awesome' by customers, is also visually appealing, enhancing vehicle aesthetics. Users are likely to make repeated purchases due to their positive experiences.

I bought this for my rock bouncer. As everything with it it was a tight fit. The master cylinder works fine but it barely provides enough volume and pressure for my application but I'm certain it would be awesome for my s10 drag car. I'll probably buy this for it. Anything negative I have experienced with it is due to my having to guess if it would work with my huge calipers and not the product itself.

The best master cylinder for 4 wheel disc brakes

I experienced the ongoing saga of finding the correct master cylinder for two street rod projects. Both cars had a 7" dual diaphragm booster and both started with the 1" bore corvette style master cylinder and the pedal was mushy. I upgraded to the 1 1/8" bore corvette master cylinder and it was better but it wouldn't to lock up the brakes. When switching to the Willwood, we now have a great pedal and 4 wheel lock up. The key feature is that the primary circuit has a 2:1 ratio that pushed more volume to the 4 piston front calipers. If you have 4 wheel disc with aftermarket 4 piston calipers, this master cylinder is the way to go.

Will look great under the hood. Very nice product.
