Brake Drum Madness
Posted by: Chi2 ()
Date: February 09, 2014 05:02PM

I've been trying to remove a stuck rear brake drum on my Rampy for over two hours. It has been quite frustrating! I searched the forums and found a few threads that advocated penetrating oil, hammers, heat and all our nuclear war on the drum. I heated the drum red hot where it touches the hub. I smashed it with a brass hammer, and a min-sledge hammer, but I was getting sloppy and I don't want to ruing the studs/threads. I pried it with bars, etc..

I tried all of these things, but that drum has barely moved. It is clear that the drum is sticking to the hub (I can bend it out around its circumference from the backing plate). The only thing I haven't tried is buying Dean's new tool, but I don't want to drop $100 just to get this turd off.

My FLAPS do not have a puller big enough to try on the drum.

Any suggestions? Btw, I have attached a photo which shows two indents where, I am guessing, I might be able to punch our the tabs. Maybe this is where a puller should go? (PS: I just reviewed the picture, and the PB Blaster oil made the photo really shiny- sorry. The two punch-outs are at 12 and 6 o'clock).

In my 64 GB there was a clear way to do this: a hole allowed access to the star wheel adjuster. Sorry- I just edited for clarity (I had misunderstood): Yes, I adjusted the shoes down.

I have had luck working an air hammer around the hub and studs. It makes a mess of the drum though.

The drub is probably toast from the prying and pulling making the center warped

Parking brake is off. I was using map gas, but it sounds like I'll need to get my acetylene torch out to really get crazy. Sounds like the nuclear option to me...

I need to replace these drums anyway (they are ancient and very rusty).

The air hammer idea sounds good and I do have one of those.... I think it is a little late to go at it tonight- don't want my neighbors to get pissy smoking smiley

Tomorrow I'm going to heat that mutha to 5000 degrees and air hammer it into a pile of scrap metal!!!!

Get a propane torch. i use mine all the time. you dont need to go crazy. probaly the center of the drum is wedged to hub. could be wrong drum being hole to small.

Use a small zip saw to cut drum off on hub. closes to outside. then you can wedge a chisel between the drum plate and hub prying it off. . Ive had to do this on a hyway tractor that had 2 millon kilometers as drum never been off.

To what Dave says, I've sprayed PB Blaster into just about any open orifice on that drum I could get at then tap it a bit and rotate. Repeat process again then tap it harder with a hammer. If that doesn't do the trick, I'll spray again, rotate, spray rotate then come back the next day and it worked. Of course, your results may vary!

Ive also had to hammer studs in then get into car and do a brake stand with wheel off. this will spin the hub and not the drum.

See the two big holes at top and bottom of picture? Pound a big flat screwdriver in the hole towards the hub. I have some hooked tools that go in those holes but screwdrivers will work.

I was wondering if that would work!! Thanks for the feedback.

So I guess they are punch-outs?

heat-especially the little you get from propane/mapp gas-won't do anything,,even acetylene unless you plan on cutting them..I'd do what Jason said, knock the studs in and get the axle to 'spin' inside the drum using both fwd and reverse..watch out tho, the drum will take off (lethal projectile) and you may push the whl-cyl pistons out..

The best course of action is to use the screwdrivers! This puts the pressure where it is needed. Do not put the screwdrivers straight towards the axle but rather anle them so the will miss the studs and the center of the axle. Two screwdrivers, one on each side, tap them in a short ways and the tip of the screwdriver will probably break, expect it. Then hit the outer corner of the drum where the web is pinched in, tap the screw drivers in some more hit the outer edge of the drum. At some point the drum will snap free of the axle pilot.

To start with use a 6" screw driver and then if needed move to the next larger size.

The "Motohead Method" is time proven. Passed down from generation to generation of mechanics, it may not be the fastest but it works. You don't even need use a Motohead size hammer.

If you try the "tried and tru" Harbor Freight pry bars and a hammer,instead of screwdrivers, it will pop off. ...the ones that are round at the top and pointed at the other end.
