    Hayes Stroker Gram rubbing

    I have a new set pf Stroker Grams and can't get the front to stop rubbing. Maybe I am being a little picky because it is scrubbing some but the back one doesn't I have tried the business card trick, removing some fluid and aligning by eye and Hayes even sent me a new rotor. Any ideas and please don't say buy something else.
    Thanks...

    Personally I like feeler gauges ( .015") between pads and rotor while grasping the lever snugging caliper bolts one to the other until tight. If your getting contact on one pad only it could be a lazy piston.

    I am sure the feeler gauges would probably be easier than trying to put cards in there. The rotor is not quite perfect, but neither is the rear and it doesn't rub at all. They have bent sent back to Hayes and they say there is nothing wrong so I am at a loss. I'll read that other thread and go from there.

    Thanks for your reply

    The video is very well done with nice tips along the way, a few MTB techs had some great responses after viewing.

    If I come across a lazy piston that doesnt respond to lube I will use a thinner feeler gauge on that side until the 2 grasp the rotor evenly. Sometimes its a fluid problem pressuring the 2 sides, think hose on one side bleed on the other when you squeeze the lever you wont get a perfect pressure on the opposite side of the hose. The bleed is on the other side because the fluid has to pas from one side to the other the air pocket will be trapped on the other side.

    Another possibility is the caliper needs to be shimmed in towards the spoke if the inside pad is dragging.

    dogonfr,
    The calipers did the trick so I have no rubbing at all. The new rotor Hayes sent is a little warped and the facing on the shock is not straight so it still took me a while. Either I am having bad luck with warped rotors or there is something wrong with my wheel.
    Thanks for all of the help.
