[AT] de-greasing disc brakes

[Cecil R Bearden]

I have had those mechanical disk brakes on an Oliver, Moline, Massey, 
Case, and Belarus.  My older 96 Belarus you have to stand on the brakes 
and usually when trying to position something with the loader you have 
to use the Parking brake which is an auxiliary band to  stop the 
tractor.    The newer one 2003, works great, and the park brake slips 
because I have forgot to release it a few times...  Both are mechanical 
disc, I am going to get into the older one this winter and find out why 
it does not hold.   However, both sides do not hold equally!!!!!   
Usually you have one side that will slide the wheel and the other that 
seems to be connected to the throttle!!!

When you adjust these, you have to leave enough travel for the actuators 
to spread enough to make the balls inside turn enough to keep the 
corrosion worn off of them...  Not real scientific, but oversize linings 
was not the thing to install back in the early 70's when I worked on 
Massey Ferguson and Olivers....
