I would like to know how to remove the rear break drum for a 90 lancer.
also are there any forums for older lancer models?

 

Have you ever done drums before? They're all pretty much the same, do yourself a favor, get yourself a set of brake drum tools, they make things a lot easier. If you're planning on replacing it I'm sure you know to do the shoes as well. If you havn't done it before I'd reccomend getting a workshop manual to help you with it. There's no real trick to it other than taking off the wheel and usually banging and prying on the drum for a while. Then you have to deal with the springs, that's why you'd probably wanna get a manual. Hope that helped.
