Default Strange rear drag problem help!!

Im in the process of installing my rear strange drag brakes.I have a moser 12 bolt sjm says I have to use a shim bearing behind the axle probles is if I use it the roor wont set flush on the axle hits the backing plate.So i took the bearing out and the rotor still will rub on the backing plate anyone else run ito this problem?Thought this was going to be a easy job now Im not sure why the hell I bought these brakes not worth the aggravation.

drag brakes need to be set-up/shimmed versus a std rotor and caliper deal. Every car can be a little different (I spent 7 hours shimming my front race brakes to sit right, but I expected this b/c the company had just started making them and needed feedback). You might want to post this in the brake section as well to see what feedback you get. Hang in there!

I no they have to shimmed to geet the caliper to sit right,But my problem is the rotor has to sit flusk on the axle correct,When I slide the rotor over the axle it hits the backing plate it needs 1/8th" to sit flush on the axle.

As I mentioned, more work involved. Hopefully others will chime in here.

We have the spacer for the axle bearing. I goes in the housing between the bearing and pushes the axle out the correct amount.

When installing Strange brakes on a Moser rear, you must use the shim that Steve is speaking of that goes between the housing and the bearing. The second item would be the shim washers for the caliper spacing. If you have done both of these steps, pictures of your issues would help greatly in finding your problem...

I just realized what you said here. There isn't any backing plate used with Strange Brakes. Just a mounting bracket, caliper and rotor.

Dave I've seen a couple cases where the shim behind the bearing wasn't enough to get the axle out far enough, and the problem that you're having was the result.

We did space the rotor hat out with washers, we used a thick steel washer and put them on the axle first, then the hat, and it solved the problem. I don't know why, but for some reason that was the only way we could deal with it. I don't feel too bad about doing that if you have 5/8 studs in the rear, they're strong enough to not have that be a problem, but if you don't, then I would be a little hesitant.

There's no chance that the actual brake disk is mounted to the wrong side of the hat is there? That's the only other thing I can think of that might cause the problem that you're having.

One other question, do you have the backingplate/caliper mount with the groove side toward the alxle bearing? It needs to g o that way. Flat side out.

That's another possibility.

They're a one piece rotor...
BTW. Washers behind the rotor is a terrible suggestion...

The new ones aren't, the actual brake disk bolts to the hat, at least that's what Dave said when I talked to him yesterday, without seeing the actual parts and problem it's hard to troubleshoot over the phone.

BTW. I don't like the idea of the washers... but I've seen it that way on the orange car Ken and Gary used to have... and several others over the years. Sometimes the ends of the axles aren't right, or who knows what else it is... but if that's what has to be done to make it work there's not much else that you can do.

I have the smooth part of the backing plate facing out so thats not it.JL I did the washer behind the rotor cap and that was enough to clearance it.I dont see any other way of doing it.I dont have 5/8 th studs though Im going to get that done soon though.

ive got a moser 9inch with the strange drag brakes and when it goes together make sure you put the shim inside the housing then the axle with the bearing on it and then the caliper bracket with the flat side sticking out and make sure your stock backing plates are in the trash or sold,ive seen it where theyve tryed to put the shim in between the axle flange and the bearing witch is not the way its suppose to be...moser and strange use differnt housing ends and the axle flanges are also a diffrent offset hope this clears it up sum iknow most of its already been said

I have a moser 12 bolt, and had to use the spacers, got them from Madman.. I did notice that when I changed the seals, the package had the same number on it, but was not the same thickness.. It didn't go on right.. I figured it out quick.
