brake caliper slide pin alignment trouble

With your caliper removed, I would try to put a straight edge on the caliper bracket at the holes and compare it to the rotor for parallel. It's the threads in the caliper bracket that determine if the bolt is going across perpendicular to the rotor. You may have to remove it, apply some heat and pressure to bend it straight again. ..or perhaps someone cross threaded it in the past?

.

The pin makes contact with the outboard spindle mount hole off center before it mates with the threads in the inboard spindle mount hole.

I can start threading the pin through the outboard mount hole on either the top or bottom mount point, but the remaining pin then will not line up without putting things in a bind (I can get the second one started by applying pry bar pressure but it is way too tight).

I'm not understanding the straight edge parallel to rotor comment.

Thanks,

You can try the other caliper on the side giving you problems . The mounting should be the same the only thing different between right and left is the bleeder orientation . If it goes on then the caliber is the problem if it’s the same something wrong with it the spindles mount .

I suggested a variation of the same suggestion in post #4. Maybe now he'll follow our advice and solve his problem.

Yes you did. Thank you! Had some other things take me away from it so this will get done however, I have verified the issue is most likely user error or the the spindle is not right. I purchased another caliper from a different parts house and found it too doesn’t line up.

I’ve done the rotors and pads brake service on this truck in the past without trouble. The calipers were sticking in this case. Only difference is new calipers and I’m not going back with new pas right now. Maybe I should as that would align the caliper over top of rotor more precisely. Come to think of it this is the first time I’ve attempted reassembly without all new rotors and pads!

I appreciate your help Sir.
