Nov 1, 2021 / 1989 Case 580L Hydraulic fluid coming out of differential vent when brakes applied #1 A aRTeDee New member Joined Nov 1, 2021 Messages 1 Tractor 1989 Case 580L backhoe I am working on a 1989 Case 580L. I pushed the brake pedal, it went to the floor. Master cylinders are not leaking, no leaking hoses. When I try to pump the pedal fluid comes out of the differential vent. Any ideas?
