IHC464 - break bleeding

I have copied the following from the training notes from the service course at I.H. in Doncaster England.PTO eiter FULLY disengaged or FULLY engaged.Engine at 16oo RPM.Plastic hose on bleed nipples both open. Bleed with brakes latched together. do not pump pedals as oil supply will not make up fast enough. Allow pedals to return vry slowly. When one tube is free of air close that bleed screw and continue still both pedals latched together untill second pipe is free of air. Hope this helps.

My experience has been make sure transmission hydraulic oil is warm. I don't touch the brakes at all, just as above engine 1600 RPM, using 2 clear poly tubes on brake bleed nipples, open both bleed nipples and let Hydraulic oil flow into container resting on drawbar. When hydraulic oil comes bubble free close nibble and wait for other side to become bubble free and close its nipple. Test brakes. If this doe not fix the brakes then there is some other more serious problem.
Be careful not to contaminated the Hytran hydraulic oil with other types of oil. This happened to my brother by hooking up to a romote hydraulic cylinder that had been used on an old Ferguson that used regular engine oil and worse than regular oil it was detergent oil so it frothed and bubbled in the IH transmission/hydraulic system. Required complete drain and purged of everything, brakes, power steering and transmission.

Good luck
