disc brake caliper not parallel to rotor
 

Long story short my rotor is straight and my rear caliper isn't parallel to my rotor. Anyone have any tips on adjusting "tilt" of the calipers? The top is to far out(away) from the rotor and the bottom is to close. Google doesn't seem to find this answer anywhere.

Cable hooked up ? loosen mounting bolts , hold the brake on, tighten bolts

without loosening the caliper grip on the disc.. it should self align..

Mechanical. Hydraulic, model, brand? not much to go on. A bit more info, or photos will get better answers....

+1,
Assuming the rotor is in roughly the right place, there's float in the brake mounts. Use the applied brake to set the caliper square to the rotor and tighten.

OTOH there's only limited float, so you might have to add spacers to bet the caliper close to home, then use the brake-on trick and tighten.

Before adjusting the caliper, ensure the wheel's hub axle is fully seated in the frame's dropout. Install the rear wheel with the bike upright and vertical, so the weight of the bike helps the axle fully seat.

Thank you for all the replies everyone.

First they are mechanical Hayes gx2 brake calipers.

Second my tire and rotor are seated. I tried 5 different ways to seat them.

The brake pads are around the rotor. And they aren't rubbing. But barely.

The top of the brake pad is almost touching the outside of the rotor. The bottom is almost touching the inside. Shims won't work unless they are angled.

Its as if my rotor is bent, but its the caliper bracket.

Any ideas?

Your mounting points may need facing. Hayes brakes do not use conical washers to compensate for tilt, so the mounts need to be perfectly aligned for the pads to be aligned with the rotor. If the mount is misaligned, facing will not help and you may need to do some careful filing to get the pads aligned with the rotor.

+1 A good shop working the MTB crowd should have the tool/jig for it.

Or switch to Avid brakes. Avid boast about their Tri-Align system, which ought to be able to deal with that.

Another set of blind guesses, to answer a question better resolved by taking it to your local bike shop,
where they can see what the issues are..

I was hoping some one night know about a tilt screw I didn't. I was trying to avoid the bike shop for money reasons. But I may just have to have them look into it.

The facing question , take them off , look , send pictures, the facing, if done, should leave tool marks.

I'd know better if there , and on the stand in front of me..

you need a macro focus and plenty of light, to actually show the caliper to disc gap relationship.

mere words fail.

Its a 7 year old bike. Like you said its so small of a crack, I wonder if my pads are worn at an angle. I ordered new pads that should get in today. Well see if that fixes it maybe. Its hard to fully tell but it looks angled.

Seeing it next to the caliper it looks straight. And since it squeezes the rotor to the inside, it appears that the pads might wear at that squeezed angle.
