    Brake Drum Question

    My 74 eldorado sat for about 10yrs. The wheels were locked up...

    I took the drums to see if they could be turned the guy told me that they were at the max.

    My question is:

    Since they are at the maximum, can I sand out the little groove (from shoes locking up) out of them and use them again?

    The cheapest ones i can find new are like $90 a piece....

    Thanks

    Re: Brake Drum Question

    I can't imagine then costing that much! Have you checked the salvage yards for a turnable pair?

    It may just be a personal preference but I don't like to do a brake job with worn drums. The reason for not using thin drums is that they tend to heat up quickly causing fade and possibly cracking.

    Yes, they cost that much...(napa, advance, haven't check AZ yet) I want to do the brake job, so I'll end up buying new... one now, one later......

    I went to pick n pull and had them run an interchange for me, unfortunately eldorado are in class by themselves with drums........

    Thanks

    Thin drums flex under load and the brakes go to hell when you need them most.

    No offense, but what would you buy anything brake related out of a salvage yard for a 1974 Cadillac?

    Its not really personal preference not doing brake work with worn drums/rotors, its more of a safety thing.

    74eldog,

    Buy the new drums, your much better off spending the money and doing it right.

    DA !!!

    Everything brake related will be new. Doin it right isn't even a option.

    Every now and then you can run up on a good set of drums/brake parts at the bone yard!!!!

    I agree, but as RedGalant2k1 mentions, it may be difficult to find good parts for a '74

    I hope you mean doing it wrong isn't an option

    Re: Brake Drum Question

    I would have no problem using a good pair of used drums. Rear brakes are only 30% of your stopping if that. I'm not denying the fact that we should do it right. Hmm I guess I'm assuming that we're talking about the rear brakes?

    Brakes are a safety issue and should be done right without skimping or cutting corners. However in the case of an older car a good pair of used drums will work fine if you need to save some cash. I found a beautiful pair of drums for my 67 Camaro that didn't even need to be turned.

    If your going to do this you certainly don't want grooves in there, that will only cause premature shoe wear and less braking surface. If the wheel cylinders are even a little rusty think about changing them and definitely get the spring kit and replace all the springs.
