Hayes HFX, is it possible to allow more caliper clearence?

Well, both of my rotors are slightly bent, and while I've tried to true them they just keep rubbing. Is it possible to adjust Hayes hydruallic disc brakes so that they stay further away from the rotor? I keep readjusting them using the card trick, but after a few miles of riding the pads have shifted again and it's back to a slight rub.

hayes pistons automatically adjust themselves for pad wear, which means they automatically adjust themselves to be close to the rotor. There isn't much you can do to stop this, though you should make sure everything is nice and clean in there so the pads can retract all the way.

Just spend some time to fix your rotors, or if they are too far gone buy some new ones.

i imagine it would be to slide a card next to the rotor and then pump your brakes so that the pads automatically adjust to the wider braking surface...then remove the card

Put a card on both sides of the rotor, then rotate it so the most bent point is between the caliper, with the cards also in there. Loosen the caliper holding mechanism (2 bolts on the bottom), shift them around, and re-tighten. It will align the caliper so that it is shifted over and doesn't rub the disc. It works okay but after several hard hits mine shift back...

It actually worked very well for me, but I think I didn't tighten the caliper down tight enough again and thats why it shifted
