Hi.

I've just, this evening, fitted Avid Juicy 5 brakes. They were really easy to fit (unless I've missed something), but now I have a query.

As these are my first set of discs (yes, really), I'm not too sure what I should expect etc. I did exactly what the instructions said to do, but I'm a little concerned about the rear rotor.

When I spin the back wheel, it runs freely and the rotor does no appear to cause any conflict with the calliper/pads. But, when it spins it does sound like something is rubbing...but only slightly. The front rotor also allows the front wheel to spin freely too, but there is no audible evidence of rubbing at all.

Is this normal? I've tried to loosen the CPS bolts and pump the brake lever 5-6 times a few times as instructed, but there is still a slight rubbing sound on the rear. Is this classed as 'rotor drag' even though the wheel is allowed to spin freely?

Cheers

    sounds like there is a little bit of play there. or the disc could be just touching the caliper somewhere.

    just go and use them for a week or so they should settle down.

    Welcome to the world of Discs... wait till they start squeaking like a mother b1tch!

    A bit of scraping ain't so bad, so long as the wheels still spinning freely. Excessive amounts causing the wheel to come to a halt a lot quicker would be problematic. They'll need bedding in and stuff anyway so best do that first and tweak later - like Nick says though they'll prolly settle down...

    I take it the shifters are on now too?
    get on your bikes and ride!

    I just managed to get the shifters on last night, but I've yet to set the gears! :x I haven't got a workstand either, so that'll be fun!!! :?
