Title: have problem with my 38 chevs brakes
Post by: Jonny Hotnuts on January 12, 2010, 12:07:28 AM
I dont know where I should post this but here is my problem:


I have a 38 chevrolet truck that has been sitting un moved for about 15-20 years. My L front and R rear drums are locked up and I can not remove the drums. THe drums are as if the shoes are tight to the drum and the wheels wont turn.

I was going to cut off the drums and replace them but I can not find replacements. I have also considered drilling the outside of the drum and using a punch to tap the shoes back.

I was wondering if anyone as any suggestions in removing the drums, or has a set of drums I can buy.


I am very much at a loss with this and dont know who to talk too.

thanks for any suggestions

The shoes are rusted to the drum.

Kroil and some soak time should get it. It will ruin the shoes, but they need a retread now anyway.

Once it's soaked for a few days tighten the star wheel (adjuster) first then back it off. Hopefully it will still move or you may have to grow the drum slightly with heat to get it off. Just remember cast iron doesn't like heavy banging, a few heavy but careful taps can help if it's almost there.

  I would unbolt the springs and drop the whole spring and axle assemble out. Now order and install your new cross member set up for the new Mustang 11 disc brake front end. End of problem!

Don't know anything about early GM stuff, but on early Ford stuff, I adjust the brakes for maximum clearance then unbolt the wheel cylinder and anything else (internal) that can be loosened.  Then spend as much time with a big dead-blow hammer as necessary.  Sometimes, a hot wrench is the only method that works  :-(

Big lead hammer, and a blow torch will normally do this.

Get it really hot, then beat the living snot out of the sides, all around.

For the front- Remove the outer wheel bearing and whack it w/ a b.f.h. (no heat) Should fall off.

Thanks for the advice all.
Buying a new jack (mine are all currently being used elsewhere).
Will try these suggestions until I find one that does the trick.

Would you believe that it just happened that way, the truck was painted some 25 years ago and I chose green just because it was on sale at the paint store (it was returned and I got it for a steal).

Funny thing is that if you squint your eyes the nose of the truck looks very similar to the nose of the Fiat!
LOL
