I recently went to Canadian Tire and they have two different types of drums for a 1998 2.2L Cavalier.
Something to do with offset I believe?
Does anyone know some #s as to what kind of Drums I should get?
the ones i have now say 7.929 on the side of them - or 201mm - this is the max diameter I believe - but not sure about this offset?
any ideas would be helpful. I did try a search and could not find anything.
Thanks,
Last time I got rear drums at a parts store, they to had two 'types' available. The only difference was the length of the warranty. I, of course, got the pair with the higher mileage warranty!
More than likely it all stems from the quality of metal used in the drums; better resistance to wear.
They had different types - 50$ ea for the high quality - down to 25-30 for the lower quality
But on each type or quality of metal, they had different types of dimensions beside them.
when dealing with brakes i always go with the higher quality. the $25 drums are made with crappier metal and have a higher chance of being out of round right out of the box. i have had to turn some brand new drums because the customer wanted to save a little money and go with the cheapies. get the more expensive ones and it should save you a headache or two down the road.
what do you mean by dimensions? what were they?

you're correct about the dimensions of the drums... difference in drum size only; not offset.
that is the max diameter limit of which the machinist has to remove B4 they are unserviceable (they'll warp on u afterwards).
these models had 2 sizes of drum brakes: 200mm x 45mm or 7.87" x 1.77" vs. 225mm x 45mm or 8.86" x 1.77"
looks like most of us have the smaller drum size...
i verified this by going to www.partsamerica.com to see online part #s/ dimensions.
I had to do this before going into the store to get the correct size shoes for my lil sis' car.
there's other websites u can confirm on this:
www.autozone.com

thanks Earl!
Those ARE the dimensions they showed me.
Now which ones can I use?
Should I still go with the small ones?
or is it ok to go with the big ones? does that mean they last longer or brake better?
or just for a different cavalier, and i should stick with the 7.87" ones.
thanks!

umm, u can't put bigger drums w/ the setup u have... it just won't work... drums-to-backing plate fitment problems, brake hardware setup, etc... i wonder who has the "bigger drum" setup... mebbe the commercial /company cars??? I see a state issued cavalier that runs on compressed natural gas in my apt complex's parking lot....
now those other people talking about different metal quality in the manufacturing process... different stores carry different brands... heck it's your choice if you want Raybestos, Allied-Bendix, or the Delco name brands... when i go cheapo via autozone, i just check if it is made in USA/Canada... the ones made in china/mexico would suck @$$ (from experience).
