IH 856 Breaks hanging up

jdb3631 · Mar 11, 2009

I just rebuilt the breaks on my 856 tractor, I replaced all the seals, orings, disks and springs. I cleaned and sandblasted all the parts and cleaned them again before assembly. every thing went together just fine and the breaks worked great till I drove the tractor 10 miles from home and the break on the right side (furrow wheel) got hot and now the breaks sticks, and gets hot every time I try to us it. Im planning on taking it apart this weekend is there anything I should be looking for??? Thanks for your help Jason

Sounds like the springs are not doing their job or something sticking! The CaseIH online catalog has a exploaded diagram and part numbers that are printable. This may help as I noticed one part had to be installed with the correct side facing a certain way. David..........

Did you readjust the self adjusters before you reassembled the brakes?

Which style self adjuster do you have , I think first 856 had same as 806, on that style the wear inside housing can make them adjust up too tight. I have ground off ends of adjusters to get more clearance on discs. (memory not 100% on that). Have to make sure the screw operates freely and spring on adjuster is ratcheting properly. Also the return springs have to be in good shape. On the tube type adjusters, each one has to be reset and spring checked to make sure it will move plate back after aplication. In any case, you no doubt have a lot of worn uneven surfaces on drum and plates, ideally you machine all parts and measure up to obtain correct clearances. Jack up wheel and it should turn freely after releasing the brake on these dry style brakes and have like .030 clearance between discs. .
