I know there is a forum posted on brake pins already. I would just like to thank anyone/everyone whos giving information and to making this forum/page operate. You all have excellent veiws and opinions so I say thank you and this is my story.
I've been working on freeing my brake pins for 2 weeks now. I just got one to move 1/16". I have the pin taped for a 7/16" bolt and a socket as a puller. I have a long journy ahead and one complete side to still get freed. Doesnt help the tractor was sitting outside under a tree for 19+ years.

I removed the brake covers and sprayed KROIL down there good [ blow out debris 1st]. Soak from outside also. Keep applying Kroil every 2 day's or so, I buy Kroil by Gal, best price and it works!

Oh boy - this sounds like fun! I expect that I may have this to look forward to on the WD45 (pix tomorrow) that followed my home tonight....

One thing to keep in mind is that the old brake linings usually had asbestos in them. Be careful when blowing the crud out especially if it is really powdery and dusty. Might not hurt to at least wear a dust mask!

Another point to think about as well, the pin goes through the front and rear brake shoe. Because of the dirt, varmit leftovers, and whatever else lived in there, the pins could be rusted to the shoes. I had that on one side of my 45. Had to clean what I could out the bottom hole, and then soak over a week or so with slick'em. After about a 2 hour battle of in and out, the pin came free. Lucked out on the other side, pulled right out. Success! Good luck, those pins are stubborn.

Dang John, why didn't you say that last week?LOL! I just pulled the brake pins and brakes off of my C. I didn't even think about the asbestos lining when I was blowing out the mouse turds, brake lining flakes, rust, dirt, grease, and lord knows what else. I really should have been wearing a mask anyway, but I just didn't think about it. Good advice for everybody. I feel for ya'll with the WD brake pins. B/C pins aren't that bad, but they aren't easy either. Harder to get the brake shoes out of the housing than getting the pins out.

In each axle housing I had a nest and acorns. I shop vacced everything out not to make much dust. I do see I have rust built up on the pin inside the housing and imagine the shoes are rusted to the pins. Where I work we use "THRUST" penetrant oil. I think this product is awesome. Anyone have experience with that product??

Is their any advantage to making new pins out of another material? stainless with a threaded end or steel threaded plus with a larger knob for puller to grab. I do not really want to put the same back in, even though I will never change them again.(barring tough plowing)

I had a real tight one last week, huge mouse nest in the housing. I finally had to cut it out with the blue wrench-which is always a messy job, but it wasnt gonna budge. I keep a couple of spare pins around most of the time.

Pins can be made from 3/4 cold rolled stock.

Seems like someone makes a brake pin puller. Can't remember the guy's name right off.

I have never messed with brake pins,but why not make them out of a piece of 4130 chrome moly tubing,square the outer end,then cut threads on the inside,thread in a bolt and pull it out?

Thought I would be smart and use my impact to jar the pin with using the 7/16" bolt and a socket as the puller. I moved it 1/8" today but still not the results desired. I wont have time to work on it tomorrow for I have ASE testing.
