The brakes on our 9500 combine were sticking occasionally (and would get pretty hot). We took the drum off to clean the brake area up and see if that would solve the problem. In order to move the little cylinder inside the drum (to allow the brake shoes to close enough to get the drums back on), we had to drain a bit of oil out of the system to relieve the pressure. Drums are back on and the emergency brake works fine but neither the right nor left brakes work. We can push the brake pedals right to the floor with no resistance. The operator’s manual is of no help. We contacted the JD dealer yesterday morning and he gave instructions as to how to get oil back in the lines (ran a hose from the bleed screw on the master cylinder to the bleed screw on the brake). We did that, blew brake fluid from the hose into the lines and think the lines are full of fluid but still, no pressure. Does anyone know the key to getting the brakes working again, short of taking it in to get fixed?

Problem has been fixed. The pistons in the master cylinder were seized. Moisture must have gotten behind the rubber boots at the front of the master cylinder, maybe from pressure washing. We took it apart, shined up the cylinder walls, bled the system and now both brakes work just fine.
