Hayes Stroker Ryde Brake Question

OK, so after changing a rear tyre and refitting the wheel, when I spin it I hear the brakes rubbing the rotor a bit, nothing too much but noticeable. I mess about with the QR a bit and still the same. I take the bike for a quick spin, no noticeable drag. Free spinning the wheel, brake still rubbing the rotor. I take off the rear wheel and inspect the brakes and one pad seems loose and not firmly against the piston. I loosen the two bridge bolts on the side the pad was loose and the pad seems to click back into place. Tighten bolts, wheel back on, no rubbing, excellent... I then apply brakes and the rubbing starts again :? . So I loosen off the bridge bolts again, now with the wheel still on and tried applying the brakes. This time a splash of hydraulic fluid hits the floor :shock:. So now, my brakes still rub the rotor and requires a much harder pull on the lever to stop the wheel.

Am I now in a position where I need to bleed the brakes to get my level pull force back to where it was or can I just 'top up' the fluid?

Also anyone got any ideas on the loose pad?

This is the first time I've tinkered with the brakes so be gentle if the answer is obvious :wink:

    what do you mean by bridge bolts?

    sounds like you have split the caliper allowing fluid out and have contaminated the pads.

    clean rotor, new pads and a bleed.

    The bridge bolts are no. 16 on page 8 http://www.hayesdiscbrake.com/wp-content/uploads/2010/04/Stroker45-21883EnglishWeb.pdf and I suspect you are right about splitting the caliper. The error of my ways seems obvious now but didn't when I was getting frustrated at 11:00 last night :oops:

    As for the loose pad, which started all this off in the first place, any idea why a pad would not sit against the piston?

    dirt on the magnet?

    Good shout, take pads out and give a good clean I suspect.

    Also I'm not sure that I've contaminated the pads. When I say a hard pull on the lever what I mean is that the lever pulls almost to the grip and then stops the wheel, which seems like not enough pressure in the system, likely due to some of it being on the floor...d'oh. Can you top the fluid up in these or do you have to bleed the system?

    I would get then bled.

    read how in the manual. :wink:

    and see how they go.

    Cheers for all the advice. Today's lesson then is to read the manual first :)
