1440 brakes

Howdy,

I am working on getting my 1440's brakes in working order (after a near accident while moving it from one farm to another in which the transmission popped out of gear and the combine went freewheeling). I know the word on these old combines is that they never had brakes. In any case, I'm into the master cylinders and having an issue. The kit that I got (a raybestos kit) had pistons that were too long. When I installed everything and had it compressed enough to put the retaining ring in the end the hole in the reservoir that is supposed to feed fluid into the cylinder and then the line was over top of the piston. This is not where it should be and ended up sending fluid out the back of the cylinder instead of into the line. I took the new piston out and checked it against the old one and found it to be over half an inch too long. I tried the old piston and it was better but still about half an inch too long. Does anyone know the length of the correct piston? I'm pretty sure if I can get a piston that isn't too long I will be in business. Otherwise, I get mostly air out the line hole and oil moving out the back. Thanks in advance!

I can't offer any advise, but if you find a fix please post it on this site. I had a 1440 and the brakes never worked. Now I have a 1680 and the brakes don't work on that either! Good combines but terrible brakes.
 
Just fix the transmission and don't worry about the brakes. They will just fail again, not enough use when they sit for so long in off season. Good luck.
