1175 brakes

I recently purchased an 1175. Serial number 8740570. It has power brakes I believe. Has a valve right in front of the brake pedals on the firewall.

It had no brakes when we got it home. We got the left one working after bleeding and adjusting. Works great. The right one went from having pedal and the slave cylinder operating to no pedal (pedal goes to the floor with very little resistance) and the slave cylinder not operating. It also quit shooting fluid out the bleed screw.

Why might there be pressure to one side and apparently no pressure to the other all of a sudden?
 
Look under the dash where the rod on the pedal attaches to the brake valve, sometimes the small plastic retainer that connects the linkage to the valve breaks. You can
reach up and check the tightness of the one that works. then grab the one that does not and see if there is movement indicating it has come loose. The connection is
covered up by the boot and cannot be seen until you remove it. If the linkage all seems good I would suspect a problem in the valve, Rod.

Ok, thanks. I think the linkage on both is pretty tight, but I'll check it again. Do you know anywhere I could find a rebuilt valve? Or a rebuild kit?
 
CNH had the kit as of about three years ago. Mine was a cabless machine and easy to take off the valve. to rebuild.
I’m told and do believe they are a nightmare to remove on a cabbed tractor. I have been contemplating rebuilding
the one on my 1175 but am going to replace discs first to see if that helps my issues.
 

Update: Turns out it was the plastic clip on the right brake pedal. Got it ordered today and that should get it working properly. Thanks for the help.
