I have a brake drum on the rear of my 49 3800 that is stuck. I had it off about 8 years ago but now it is stuck tight. I have heard that they are nearly impossible to find replacements, so I don't want to pry and bang on it too hard. Any advice on getting it freed? | | | | | Joined: Feb 2013 Posts: 250 'Bolter | | 'Bolter Joined: Feb 2013 Posts: 250 | Back off the shoe adjusters, make sure the emergency brake cables aren't pulled tight, tap around the drum with a dead blow or rubber hammer and see if that helps. Probably just some rust making your job difficult. You can always put a big puller on the drum and carefully pull it after loosening the shoe adjustment. | | | | | Joined: Feb 2004 Posts: 29,749 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,749 | You can also pull the axle shaft and remove the whole hub/drum assembly. It's easier to deal with a stuck drum on the workbench than it is to fight with it on the vehicle. Once it's on the bench (or the floor), support the drum on a couple of pieces of 2X4 and smack the center of the hub with a big dead blow mallet. Inspect the bearings and replace the grease seal before reassembling the hub onto the rear end.

I hammer with a flat face on the drum where it is backed up by the hub. After a while the blows produce little whiffs of rust and that is a sign that it is coming loose. Jerry's suggestion is the safest way. You are correct that it is very hard to find replacements. | | | | | Joined: Nov 2008 Posts: 544 Shop Shark | | Shop Shark Joined: Nov 2008 Posts: 544 | Nix....I think you just pounded me on the head with a hammer. I completely forgot about the screws that hold them on. Talk about a good rap on the head to jog the memory. When the sun comes up and time allows, I will remove the screws and try again! I did get it to spin a little, but it's pretty tight. I figured it got seized up from sitting. I'll remove screws and try again before I dive any deeper. Brake lines are all removed. Prepping frame for sandblasting. But didn't want to blast until I knew I could roll it easily. I figure it is a brake adjuster that isn't aligned right. | | |
