I just bought my first Allis. A 52 WD. I love it but would love it more if it would stop. Are the brakes adjustable? It looks like quite a job to get to them so I thought I'd ask before I tore into them. Where can I find new brake parts for it? Thanks

You asked about adjusting the brakes, not replacing them, like the others told you about. Yes, replacing can be a bear, getting the bottom pin out, but what also works is to drill a 3/4 inch hole in flat stock, weld it to the pin, and if the heat of welding doesn't loosen the pin, a BFH will do the job. Adjusting: take off the top cover on each side- left side is sheet metal, right side is the cast mounting bracket for the seat. Use a 3/4 inch wrench to adjust the nut you see after removing the cover. Tighten up each one until the brake pedals have the same amount of travel. End of job.

Easy to adjust, easy to work on, parts readly available but those bottom pins can be a B___H to get out!! I was lucky on mine, someone before me had replaced the linings and used anti-seize on the pins. Good idea when you have them out!! You can adjust the brakes without tearing into anything if it is only an adjustment that is needed. Usually, unless the lineings are pretty new, what you need is to reline or replace the shoes.

Yes, get the manuals. They are easy to work on with one exception. If the pin that holds the shoes in, 3/4" pin on the bottom of the axle housing, is rusted in it can be a bitcx to get out. If you need to go back in the arcives and search on this problem. Basically you drill and tap for a puller. If you can't find anything, e mail me or post here and I will describe it again. There are some small details that help insure you are able to get them out. I repeat,They can be a real bitcx.

But you have a great tractor, enjoy it. Oh change ALL the oils when you get your manuals.

I am in the middle of removing the brake shoes from my WD45. I also cannot remove the anchor pin. Please post the removal procedure. I sure could use it.

Just did it Last weekend. The first thing I did was buy some 2" pvc pipe plugs. The kind that have a wing nut on them and when you tighten it the expand. Put those in the bottom access holes of the final drive housing to seal them up. Then I poured brake fluid into the housing until it came out of front brake control rod hole. Let it set for a day or some. I've tried all sorts of penetrates, but brake fluid seems to work the best if you can let it soak.
Then I bought some studs from the auto store, 3/8" x 3" - Fine thread on one end and coasre thread on the other. I was told to get all fine thread but couldn't get any. Then I ground off the case hardened end of the brake pin with a 4-1/2" angle grinder. It doesn't take much, only about a 1/32". Then center punched and drilled an 1/8" hole about 1-1/4" deep in the end of the brake pin. Next I enlarged the the hole with a 1/4" drill and then a 5/16" hole. Used a 3/8" -16 tape and taped the hole. screwed in the stud and used a 1" socket , a few washers and a grade 8 - 3/8" fine thread nut. I starteded tighening the nut but was thought that I was going to break something. I switched to a impact wrench and the came right out. It took about an hour to do both sides.
Let me know how it works. I've tried just about everthing including cutting the pins, and these where the worst ones I've ever seen and the came out nice and easy. Besides to buy a new set of pins, you are looking at about $70.

You have just about described my method. I would add that it is important to et the holes as close to center as possible. Use a new tap and a lot of cutting oil, you don't want to add to the problem by having a broken tap in there. Take your time and be carefull. I used fine threads, leaves a stronger stud and I think fine threads cut easier, tap is stronger too as it has more metal leftg after threads are cut in it. If you ever put new pins in drill and tap them before you put them in, the next time you or someone else has to take them out they will THANK you.
