Tractor Repair: bleed brakes, brakes, ih

Question
i just got an `86 case 885xl and no brakes. i`ve never seen this type before and just wonder if you can help. the master cyl seals are done and re-assembled. i can see a bleed nipple inside the rear left but not sure where they are supplied from? i`m hoping you can help.
regards, jonathan

Answer
most ih tractors are supplied from the backend oil through a pipe from the the power steering orbital valve as far as i know you bleed them in the normal way you bleed any brake system there should be a bleed screw on both sides bleed one side at a time with the brakes unlocked. if you still have a problem the equalizer valve can also give problems
