Caliper bracket rubbing rotor please help!!!

[Rainmaker1990]

I recently changed the front right wheel bearings, and when I went back to re install everything I found that the caliper bracket is rubbing the rotor in such a way that it will not allow the hub to spin. Anyone have this issue???


This is with the bracket bolts completely tightened down


This is with the bolts loose with some play. This give enough clearance for the hub to spin.

Please ignore what I had originally posted here. Not the same issue at all.

Anyway... It seems you need to move the floating portion of the caliper out more. As the guys below have said, you are also probably skewed without the pads in - the caliper spring
is pushing the frame crooked.

Is the rotor centered in the bracket? Was it rubbing on both sides?

Once everything is back together, it should centre, and align itself. It will most likely no longer rub. It's crooked now, because the pads aren't in.

No, it is only rubbing on the one side I showed in the picture. And yes the rotor is centered.

I had everything back together, and still the same problem.

It's either one or the other. The width of the rotor=X and since you said it was rubbing on only one side,
then obviously the width of slot in bracket=X+Z with the slot being wider.
If it was centered, then you would have a gap of Z/2 on both sides.
Since it's really not centered but is rubbing on one side only, then the gap on the other side=Z.

Trick now is to check the parts and re-arrange or modify as necessary so that the rotor sits centered in the slot in the bracket. I've seen issues with the centre hole of the rotor not sliding onto the hub properly. Try this:

1. remove rotor and inspect centre hole and make sure it's uniform and not deformed in anyway. No extra casting ridges or imperfections

2. inspect seating area on hub for rotor. It should be clean and free of rust and dirt.

3. leaving brakes & pads off and install the wheel and tightening the lug-nuts to spec

4. remove wheel and inspect rotor alignment within bracket

If it's still not centered in the bracket and still rubbing on one side, something's wrong. Time to measure the offset of this rotor and compare to the one you removed that DID have the proper clearance. Perhaps re-install the old rotor and measure the clearance to the bracket on both the inside & outside. These numbers will be handy to compare to the replacement rotor.
