La Case

Have a 49-La Case that needs rear brakes replaced. Anybody has any experience taking break cover off axel? I have been told that this could be a hard project to get apart. If anybody would have info on this I would apricate that
 
I have done them, its not a bad task. Remove the tire/rim assy by removing the lugs scattered around the wheel. The big nut comes off the axle next and then a puller will remove the wheel/drum. There are puller bolt holes in the wheel. It is heavy, like 300-400 lbs heavy, so use something to handle it.

What exactly is wrong with your brakes? Could it be possible they need fluid and bleeding or do you know that they are sure enough bad?
 
The breaks haven't worked since I got the tractor. Block was full of rust so I ended up putting Merdice acid through block. Going to put water back through system again. If it
runs ok Ill change it over to antifreeze. Tried to run motor couple times, kept getting rust in Radiator. Didn't know what to do to get rust out of motor. I figured since I have a little time I would check Breaks out. Need to replace wheels as calcium has eaten wheel up pretty bad. Hoping it wouldn't take a lot to check brake pads.
 
Here is a visual of what you will be dealing with on the brakes.

Your shoes may be OK, but I would bet that your master and wheel cylinders are full of rust.

Ya this tractor sat in a shop for 10
years. Then was moved outside due to
storage area needed. It Had a big loader
on it. Last years of service was loading
silage and cattle hay.
 
I had pulled the water pump off and removed the 90 on front of valve head. Was about 2' of rust filled up at back of block. Built a 1/8 coper tube that I could get into back of motor. Shop was plum full of dust when I finished blowing block. Valve head was the same way. Everything I had read on YT said that blowing block out would not fix problem. That is why I tried Merdice Acid. Thanks for all your help, guys.
 
I pulled wheels of the LA Case that I want to
check the breaks on. I have mounted a puller on
the end of the wheel. Turned the puller as tight
as a 3/4 drive air impact would turn the rod. Hit
the end of the pulling rod with a sledgehammer
several times with no reaction to break assembly.
Would heating the cast piece up help? If there
are any ideas that would help,I would try them.
 
Heat can always help, be careful, it is cast iron. It will take more force than what a 3/4 impact will do. I have had to put my 75 ton cylinder on them to break them loose. I have got them loose with a 1 impact using a 1-1/8 UNF rod ans full nut, it didnt just come right off. YMMV.
 
I'm sure the master cylinders are bad, I thought
I would check the brakes out while I was working
on this part of tractor. Was hoping it wouldn't
get into a big project. I have equipment that can
handle the weight. I didn't want to do something
that would damage something.
