Return PolicyWilwood’s tandem chamber master cylinders represent the latest refinements in brake pressure actuation and fluid control. The exclusive Wilwood features incorporated in this innovative and unique new design make it the perfect choice for a wide range of custom manual or power brake applications.
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.

I've built a '32 Ford using a brake/clutch pedal combination supplied by the chassis builder (Brookville Roadster). I mounted a 1" bore manual MC under the floor and installed disc brakes front and rear. My problem is that the pedal effort is extreme. Turns out that the brake pedal is only 4:1 ratio. I now realize that my brake system is probably the worst possible combination in terms of pedal effort. It's OK for moderate braking, but I'm not sure I can press the pedal hard enough to make a panic stop. (I estimate it'd take 200 lbs of pedal force.) There's absolutely no room for a power brake MC. I'm considering replacing the MC with a 7/8" bore. That'd reduce the pedal effort by about 25% but increase the pedal travel by that much. I seem to have plenty of pedal travel available, so I don't think that'd be a problem. (I've got 5" to the floor, but I'm only using about 1" - it's a nice, firm pedal.) Can you see any problems with making this switch?

1/2-20 to -3AN adapter Do you offer a 1/2-20 to -3AN adapter for the Wilwood master cylinders? I hate stacking adapters if I don't have to.

Will this master cyl work on a 57 chevy? I want to buy your tri-five chevy front disc brake kit with 11" rotors & 69-77 calipers. Also would you recommend a stock prop valve of a adjustable unit. I'm running non-power brakes & stock drums out back. Its a 4-wheel drum #non-power# car. Thank you. Matthew

"depth correction plug" mentioned in video for use with a booster.... do they come in different length's is another name for them I cant find any I am installing a master cylinder and booster in a 1953 Studebaker, I have found that the booster rod is not coming in contact with the master cylinder and is about 1 1/8" to 1 1/4" short... I saw the depth correction plug mentioned in your video and was wondering if these are available in different width's and length's... I have not been able to find anything like this anywhere, and was wondering if possibly under a different name? Or am I doomed to making one myself? Thanks for your input

I,m building a Model A pickup, GM metric disc on front & rear, 5 to 1 pedal ratio, 7" single diaphram booster. I have a Wilwood master cylinder with a 1&1/8" bore that I would like to use. Will I have enough pressure or do I need a smaller bore? Joe
