2594 Brake problem

[ColoradoBob]

Hi everyone hope to tap into some expertise before I start tearing the tractor back apart. Here is what I have going… I bought a second 2594 this summer and the brakes were a little spongy on it so I decided to replace both sides and did the PTO clutch while I was at it. Then when I removed the charge pump to inspect the bushings I found some torque limiter parts so I split the tractor and replaced the torque limiter clutches. Just got it all reassembled today. fired it up and everything seems to be working fine except my left brake. The brake pads were good, but I replaced them with new ones since I was already there along with new Orings. The hydraulic screen was clean not plugged everything looked pretty good in there. so the left brake acts like the piston is wedged possibly in the bore. I get absolutely no braking on the left side and pedal is firm with plenty of oil getting to bleader screw. The right side works great so I switched the lines coming off the brake valve to see if it was the issue and same problem just opposite pedal. Any ideas?

I’m unfortunately an impatient person so I took it back apart and found the brake piston was indeed stuck in the cylinder. Drove it out and could not find any reason it was stuck? Orings look fine so I reassembled it and tested with air and all looks well! Guess I will put it back together and try it again?

Actually just saw it. (Not sure if anyone is watching this or not but I wanted to follow up)
I had the reaction plate clocked incorrectly, so that had tightened the brake cylinder against the return spring cups blocking the piston from movement..

Thanks for the info!

Definitely didn’t want to pull it apart a second time but it didn’t appear to do any damage so that was the silver lining I suppose!!

Sometimes not going more backward is as good as going forward
