Hi all, after changing the drivetrain & wheelset on my bike I proceeded to install my new disk brakes (Avid Juicy 5s, 160mm rotors F&R). The rear one is adjusted perfectly, doesn't rub at all. The front one rubs because I think the pads didn't fully retract. I've tried putting loads of sheets of paper where the rotor goes to try and separate them further but to no avail so that's my first problem.
The second problem is the problem I realised shortly after mounting my front brake: if I lock the front wheel I can rock the bike forwards REALLY far, I'm talking about 1 or 2 cm not just the typical fork play or whatever. I'm pretty much stumped on what to do as I have no idea on this topic of hubs. Is it something to do with tightening the cones or whatever they're called? Broken axle? Bear in mind it's a brand new wheelset, has literally only 5km on it.
Finally, would having touched the rotor a fair amount during installation & the like contaminate the pads easily? Should I sand them off slightly just in case? How can I remove the pads from the brakes? (the Avid website didn't help)
Thanks in advance,
