To Case Nutty 1660, I had some help today I watched the left working brake and the slave cylinder moves the lever, pedal seems "normal". When the right pedal is applied it has much travel to floor, you can heard the main valve squeal and the slave cylinder does nothing.
Thanks again for your time and help.

ok next step can you move the brake linkage manually? I have seen them rust tight in the pivot area thanks for the update

I will check that soon, it is raining here in Alabama, and my leaves are going away from the shade tree (shade tree mechanic).
I was looking at the service manual again last nite and I am wondering if the power assist piston is not doing what it should, when you apply both pedals.
I can't seem to understand why applying both pedals makes the left non functioning.
I thank you very much for your help.

not sure I wrote it down yet but the brake valve does have a flow/pressure valve in it that does cut off some pressure when applying both pedals for a "less aggressive" brake for road travel speeds, the squealing tells me the main relief is working so that is one good thing and one more thing to check off, I do think you said it squeals when you step on either pedal one at a time right? how about if you step on both at the same time? it will take around twice the pedal effort to make the by-pass squeal this way

Yes the brake valve squeals with individual pedal pushed, it also with both pedals pushed. I have driven it some just now I am wondering if the pads/disc could be causing this problem?
I checked the lever and it was not rusted up but the return springs are broken on that side, just wondering if the self adjuster has over adjusted the right and when you press both pedal you don't get the travel far enough on the left for the brakes to apply.
Sorry for being so much trouble, I do appreciate your help. I have more experience with backhoes and dozers.
If you are tired of this problem just let me know and I will stop asking questions.
Thanks again.
