That's what I was thin king, drum was probably for a wider brake shoe. As I said, with a spacer it will work. The wider drum (and spacer) will be a bit extra weight is all, but not that much. Not ideal, but no harm either. Sometimes we have to just make what we can get work! As long as it can be done safely...

I'd be willing to bet that he has 2502 drums which are the 9 x 2.5" drums that RockAuto, and many other sites, list as the replacement part for front 9 x 2's. The 2502 has a larger center hole, so it "fits" over the hub, but the center is depressed relative to the outside so the old wheels won't seat.
The problem is that it all goes together OK at first, and when you put the wheel in place, you can't see the drum face, since the wheel covers it. But if you look closely in the gap between the big center hole and hub -- said gap created by the wrongness -- you can see it's about 1/4" out, and the wheel doesn't feel satisfyingly solid in place. I maintain this spreadsheet of PARTS KNOWN TO FIT, BY ME, here: https://docs.google.com/spreadsheets/d/1n_DJEdP70MRh6ACQarLhfzWQ9hE38HIthgVCaJv83CI/edit?usp=sharing These are parts I've actually bought bolted on, and drive on daily. If it's just "research" ("might fit") then the line item says that explicitly. From this page https://www.sr-ix.com/AMC/index.html |

If the wheels fit but don't tightn against the hub in the center, first check to see WHY they don't. If the wheel is contacting the drum further out you can use washers on the lugs for the wheel, or get aftermarket wheel spacers (1/8" and 1/4" readily available). As long as that doesn't create clearance issues with the tires (shouldn't) and the brake drums otherwise fit just fine (no big gap between backing plate and drum) you should be fine.

When was that? More than a couple years ago? Do you know what was done, exactly? Did you SEE if done? Or did the seller tell you it was done? But as others have said, start at one end and go from first principles. Inspect the back of all four backing plates; are wheel cylinders leaking? Pull off drums. Is everything decent looking? Brake dust covered is OK, caked with sticky good is not. Bleed one front brake; does fluid flow? If not, is the master cylinder super clean, shiny, filled with water-clear fluid, no rust? Cuz that's what it ought to be. If not, start there. Etc. |

Missed this... You have the wrong drums. If you tightened the lug nuts to make the wheels touch the drums you may have ruined the wheels, I hope not. You cannot buy the drums you want, Raybestos 2500, from most parts stores. They are no longer made. Check with the AMC suppliers or brake specialty places. They will be about $100 each. Big automated parts sellers have suffered from "catalog collapse" where they have mashed unrelated "similar" but often wrong parts into one. They all use the same data so they all sell the same wrong parts. |

I know no one is really caring about this thread anymore, but yes, while doing work on the 1958 rambler supers brake drums and repacking the front bearings, I noticed the rear brake drums come off right after you take the wheel off, the wheel is what holds the drum where its supposed to be, but, when I was trying to take off the front drums, I tried for ever doing all sorts of stuff, penetrating spray (didn't think it would do much) wacking it with a hammer in all sorts of diff spots to maybe lossen up some rust that was cementing it together, it couldn't figure out hwo to get it off, and was almost going to rent a puller, and then my dad suggested to try taking off the castelated nut that holds the wheel bearing in, and it worked! I was a little ticked off things seemed so hard to figure out, but I was thinking the front drums must be the same as the rear drums, but that was not true, it's as clear as carrots to me now, always think twice before assuming things are the same.

I would start at the wheels and work my way back through the system. It could be a variety of problems.

1960 Rambler custom front brake hub problem . I ordered a set of after market front brake drums and after installing them it seems that my original rims don't seem to fit right . the rear rims sit tight against the drum but the front sits about 3/8 of an in. away from the rim and I have over tighten nuts to suck in the rim to the drum. Any help or direction would be great .

Front drums are swedged to the hub at the lug studs. Remove the hub and drum by removing the bearing cap and nut. I did a friends 1960 American. It had been sitting over 10 years. All of the wheel cylinders were frozen. All of the brake shoes were good, so we replaced the 4 wheel cylinders. Bleeding was a pain with the master cylinder on the frame (no gravity help). Not sure yours is the same. Keep working at it, eventually you'll get it done. Bob tufcj
