I am using a GM mastercylinder with 1 line going to each rear GM disc and caliper. When putting in a cutter brake I assume the 2 lines from the cutter brake splice into the existing 2 lines going to the 2 calipers. Now.....what keeps the fluid from the cutter brake mastercylinder from entering the full time master cylinder instead of the calipers? If you use some kind of valve, what is it called and how does the valve release the pressure applied after pedal is pushed, then released. In short.......how are the two circuits seperated from each other? Thanks, Tom
Do I have any of you totally confused yet

No splicing necessary. The cutting brake is used inline.. Start at the master cylinder and take the lines into the cutting brake. You may have to combine these two lines into one or just use on line from the master cylinder and cap the other. From the cutting brake now go to the individual rear calipers. The cuttin brake is inline. This was covered before and may still be in the archives....good luck

I hate to ask this now.....But how do I get to the archives? I have read every post on this forum and done a search for "cutter brakes". Tom

those gm master cyl have diffrent size bores for front and rear brakes. Ive used them before just plumb them together before the cutter the to each wheel.

I understand now. I was going to make my own cutter brake setup with 2 single line mastercylinders, one routed to each wheel, and make a handle for each. Doesn,t seem like I can hook that up in the same line as the mastercylinder for the regular brakes. Oh well, just trying to use what I have laying around. I guess there are some areas where you just shouldn't pinch pennies. Thanks again, Tom

I don't doubt you could do that. Using check valves in the right places. Trying to come up with ways to use what you have is what rail buggys is all about. Go for it. ( Unless someone knows why he shouldn't).

Cutter brakes are a lot cheaper in the long rum than trying to use 2 seperate master cylinders. You would definatly have to have check valves in the output of each cylinder. These would not be cheap and they may bleed thru and you would back fill one or the other or both Cutter brake master cylinder(s) and have no brakes etc etc etc.

Firebug to the rescue again ! Just do like he said & it should work perfectly,I know because I'm the one from the archives. Bruce

I got it. Have to wait a while to afford cutter brake but am sure it will be well worth it. Thanks, Tom
