Default question on setting up drag brakes

I got my front Aerospace all bolted up and ready to bleed out and i checked out the alinment with the caliper/rotor and my caliper sits about 1/8in too far to the inside. Is this a issue at all?? Or will the pistons just adjust to it when i bleed it all out? Or ill need to space out the caliper bracket off the spindle which i dont really want to do. Do the calipers need to be set PERFECTLY centered with the rotor?

You shpild have a set of shims for the caliper bolts. Use them to center the caliper.

My Strange brakes came with shims that go between the caliper and mounting bracket to center it on the rotor. I would think that Aerospace would be similar.

i do have shims but thats not where i need them. I dont know how the strange ones mount but aerospace calipers get mounted on the backside on the bracket and i need it shimed out more, so shims there would make it worse... followin me? So i need it flush on the bracket and then some.

It's a strange problem, I have the hub style aerospace on my car right now and they went together perfect without any shims or anyhing, the rears needed to be shimmed a little, but not bad. Fronts were dead nuts perfect right off the bat.

Odd... sounds like something isn't together right or something.

Get a pic up tonite and I will try to look back here when I get home and see if it makes any sense.

make sure you take some lug nuts and tighten the rotor up against the face of the hub in case the rotor isnt sitting flat against it. You may have already did that. Just double checking

Make sure the caliper plates are on the right way, the bigger part of the steel inserts should be on the inside. The shims go on the aluminum spacers on the 3/8 caliper bolts to move the caliper to the outside.

Pic of how should look.

Kp those look like the old style brakes without the Hub.Mine are New style with the Hub.The spacers go on the outside of the Drop Spindle so that the bracket does not sit against it.Also my caliper is a little off center,but not a lot.You cold shim it out if needed.If you have stock lower a-arms,you will need to clearance it quite a bit(1/4") at the bottom near the disc.When it is at rest it has clearance,but when it moves up and down it will rub the disc.

I think both styles use the same caliper and bracket, just the hub and rotor are different no?

One thing for sure is the instructions werent very clear on anything with the the ones I have..

OK, heres some pics.. You can see that i can not shim the caliper out from the bracket because its mounted on the outside. Only way is to space the rotor inwards or the bracket off the spindle arm.

Yea thats definitely different then the old style. If the rotor, bearings and everything else is installed correctly I'd probably just leave it unless the rotor was hitting the caliper itself. Mine arent perfectly centered either..

yea the rotor is still a decent amounts away its just a funny angle. Id hate to space out the bracket off the spindle and not have it flush on it for strangth reasons.

I see what you got now. Thought they were like kp's. Im sure you would like them centered up but that should be ok.

Same with spacing the rotor in, I wouldnt do it. I wouldnt worry about it too much, just keep an eye on how the pads are wearing.

Yours seem to be alot farther off then mine were, almost like your axles went into the spindle farther then they should have. You didn't grind on them at all where the plate sits to remove rust or anything did you before you painted the spindles?

That's the only thing I can think of that would cause it to be off like that. Being that my car had very lieel rust at all on the spindles, I was able to just wire brush them before I painted mine. I wonder if that's why I didn't have that problem.

Again like mentioned, if it's not perfect, I wouldn't worry about it, as long as the rotor isn't hitting the caliper you should be o.k., just keep an eye on pad wear (mine didn't wear much at all)

Thats how mine looked before i put the shims between the drop spindle and the bracket.There is no reason the bracket needs to be up against the drop spindle,if you check it with a straight edge you will see it is not perfectly straight.

i got it all good, my drivers side was actually fine and n the pass. side i put shims infront of the hub so it moves the rotor inwards to center in the caliper. Worked out good. Now i got them kinda bled out then there still slightly off so ill have to FINE tune them when there all bled out.
