New Brake Shoes Not Fitting

Hi all,

 

I've been working on overhauling the brakes and suspension on my '76 2002 this weekend. Everything's been going smoothly for the most part except this one thing. I replaced my brake shoes with new 230mm shoes from IE (found here: http://www.iemotorsport.com/bmw/2002-brakes/02shoe.html ) and now the brake drum doesn't want to fit back on. Well, actually it does go on but just barely and involving some pounding with a rubber hammer. Needless to say the wheel doesn't turn in this state but I wanted to get the drum back on before leaving it sitting overnight.

 

Has anyone run in to this before? What does one do in this situation?

 

Thanks in advance!

 

Cheers,

Jonathan

A little additional advice.  Check the outer edge of the drum's inner surface and feel for a ridge with your fingernail.  That ridge is where the drum doesn't wear as it doesn't contact the brake shoe.  If your new shoes' linings are fractionally wider than the old ones, they'll bear against that ridge and cause the symptoms you describe.  Any automotive machine shop can turn the drums slightly to remove the ridge without wearing the drums down below minimum specs.

 

Also, make sure the drum(s) aren't ovalized--which can be caused by a number of situations.  They need to be perfectly round for the new shoes to work properly.  Again, they can be turned to true 'em up.

 

cheers

Thanks everyone for the help! I should have tried a search first, I guess such an obvious issue would be bound to have been discussed before.

 

In any case, I appreciate all the replies, I'll let y'all know how it goes.

 

Cheers,

Jonathan
