International 574 hydraulic problem

Okay. I need help with my international 574. If I lift anything that has a good bit of weight like a round bale with my 3 pt hitch when at the top it's constantly jumping. Also when I turn the tractor off it lowers pretty fast on it's own. I also have problems with my brakes I can bleed them and they'll work for about a day and I can see a little bit of fluid leaking where the brake compresses. Can this have something to do with 3 pt failure?
 
The one my dad had, had a pinhole in a part of the casting that would let air in but not let oil out. We did not find the exact location but it could get air bound and lose the brakes first the steering and
three point.Parked it on the blower and let it all summer once.You will have to find the leak first and then see if the jumping three point goes away. Our 686 we never could get the jumping three point fixed
and the shop was out several time for it. Good luck.
 

Okay thank you. And yes since theirs a leak I can only pick up so much weight and then it starts to drop down more and more and eventually I can't pick it up
 
Hi, if the 3pt goes down when the engine is off usually indicates that the seals are leaking in the 3pt lift cylinder.
The brake problems could be caused by a leak in the brake master cylinders or brake lines that run under the transmission cover
sheet metal back to the top of the axles or the O-rings on the brake wheel cylinders are leaking.

To test for leaking brake wheel cylinders, bleed the brakes, park the tractor on the level then leave it shut off for a day or
two and before starting it, press each brake one at a time. If only one brake pedal goes to bottom then that wheel cylinder is
leaking or the brake line is leaking.
Make sure the transmission Hytran level is over full by 5 gallons or more.
