Fitting Formula Oro's ?

Hi, I have just fitted some Formula Oro K24's onto my hardrock and all seemed to go fine except for the last part where the instructions says to hold the brake on and tighten up the caliper bolts.
How firmly should I be holding the brake levers ? At the moment both the front and rear brakes are catching the rotor a bit when I spin the wheel and I want to get them perfect before I head out for a test run.
Thanks for any advice.

    tight so the caliper does not move.

    and yes you will get some rub untill the pads are bedded in.

    Thanks nicklouse. I will have another go later today.

    When fitting my Juicy5's I have to hold the lever very tight and nip the bolts up slowly and progressively as the turning friction from the bolt moves the calliper far to easily for some reason.

    I find an old toeclip strap (or cabletie/laccy band) handy for holding the brake lever in for this sort of thing.

    Thanks, gave the cable tie method a go and that seemed a bit better. Still catching a bit though so will see if they settle down when I ride it over the next day or two.

    I think the 'hold the lever' works better with Avid as they have multi align brackets (that move in all directions, not nessessarily paralell to the braket) the Formulas only go left, right and up and down, sometimes it's better to just look through and see where the gaps are and align to them. tightening the bolts ever so slightly until the bolts torque does not move the caliper.

    The brake adjust method works perfectly if the rotors are rigid, unfortunately they are not, they move a tiny bit.
