Replacing Brake Drums

Hopefully I will be replacing my rear drums this weekend. I've never done brakes before, but if I'm just replacing the drums with new ones because the existing ones have been turned too many times, how do I set the self adjuster to the new drum thickness. Is resetting the self adjuster the only thing that I need to do, or is there anything else I need to check or adjust or look into?

Thanks

Hopefully, there is an oval hole on the backside of the backing plate where you can access the star wheel of the adjuster. If not, you'll see the oval and where it needs to be punched out. After installing the drum, adjust the brakes until there is a slight drag on the drum. I usually adjust them so that with the wheels in the air, I can spin the tire and it will stop within one to one and a half rotations. You probably want to check the thickness of the brake shoes while you are in there and give the whole brake assembly a good flushing with either brake cleaner or just spray off with a hose.

Thanks J4Grand. Which way do you turn the star adjuster? Will I see something moving so I'll know if it's making it tighter or looser? Do you know what the minimum safe thickness is for shoes?

Should only turn one way. There should be a ratchet type of stop that sits against the star adjuter to prevent it from loosening.

Also, might be an idea to have the new drums turned when you get them just to clean them up. No telling how good the casting house turn is when they're making money on cranking out volume.

You will have to pull the parking brake cables to get it all apart. Use a small hose clamp to squeeze the cable retainer doohicky.

I just bought new drums for my jtruck a couple of weeks ago.. When I went to put them on, they didnt fit like I wanted. Took them to the shop and had them cleaned up(turned slightly). Dont be surprised If you have to do this. If its your first brake job something like that will happen. If you can afford it I would just replace the shoes and springs, wheel cylinder also. That way your drums should be fine for quite some time. Take one side apart at a time so the other can be a referance.

If you want to get real technical, you can take your new drums and shoes to a good shop and have them arc'ed to match.
