centering calipers

[Neccros]

Whats the best way to center calipers?? Im replacing the stock wheels on my bike with another set and the new hubs moved the rotor just slight enough to cause it to rub.

should I loosen the caliper on the mount, grab the brake then tighten it??? or should I go with the business card trick with a card on each side between the rotor and the pad?

Or is there some other trick??

The trick to get quite running Juicy Sevens is; spin the wheel, while gently appling the brake, while tightening the caliper mounts.

When breaking Hayes pads in they says a few hard stops. That screws up my Juicys, I need to apply the brakes slowly taking care to never let them makes a noise while breaking them in. I ride around with the brake slightly engaged appling more presure until they break in.

Well my rotors are broken in with the pads, I just swapped the wheels themselves and the rotors are the same....

Or does your technique work the same for either??

I would think, Yes.

Post mount or I.S.?

Post mount: loosen caliper mounting bolts, apply brakes and hold, tighten caliper mounting bolts.

I.S.: apply shims to caliper mounting bolts until rotor slot in caliper is centered over the rotor.

Your business card trick worked wonders for me on my Deore hydros since the pistons never wanted to initially move at the same rate.

Im running basic Hayes HFX-9's on a Spec Enduro...

I guess its I.S.(International Standard?)

you need to use the shim method,make loose the bolts insert the shims like cal said.shimano makes shims the just slide in without taking the bolts off.

For hayes with the I.s. adapter you can loosen the 2 bolts that hold the caliper to the adapter. That will allow you to move the caliper in and out without shimming it. Since they are already broken in just center the caliper over the rotor with equal space on either side and tighten down the bolts

I got them centered.... After multiple tries with business card shims.... a shim on both sides, one side, etc but it still dragged... Finally nailed it but now I need to Loctite the bolts to keep them from coming loose...

Are your rotors warped? I could never get my Hayes to stop dragging, especially with my 8 inch rotor up front.

Nope.... they are straight as an arrow
