brake disk/caliper compatibility.
i've spent all night getting the epic ready for the mont, swapped the gears over from my enduro in prep for the 24 solo's. stripped everything and put mr new whhels on( xt with xtr rotors) the brakes the rotors are going on are juicy ultimates, now there's a massive problem in that the wheels wont turn as the alu spider in the middle of the rotor which is riveted to the outer steel disk is catching on the tabs of my brake pads. it's late at night so i havn't looked at it properley but it might be a simple adjustment issue. if anyone can shed some light on the issue that would be appreciated.
thanks gazza
p.s. if you think what i've just written seems to be in a foriegn lingo then sarcastic comments WILL offend and i WILL stamp on your toes next time i see you!

Gazza, why don't you just install them properly? Should fix the problem
Seriously though, sounds like an alignment problem (pictures would help). At a worst case you could grind the tabs off the pads?
Note to self, bring steel toe caps to the solo24.
Hi Gazza,
I had a similar set up on a bike before, xtr floating 180 rotors and Avid Juicy 7 callipers and it all worked fine.
I did use the shimano calliper mount adaptors though to get the correct spacing. I can't remember exactly, but I think Shimano's are 180mm rotors and Avid are 183mm rotors.
Maybe worth a try.

I had the same problem with the XT wheel set with XT rotors with Juicy 7s (160 rotors) with the spider hitting the tab, Adrian from Belrose Cycles suggested to cut off the tab that is catching onto the rotor spider (don't cut off both tabs, one will do fine).
When you need to change the brake pads, just use a pair of long nose pliers.
Tien.
So the tabs must be hitting the rivet type thingys that locate the disc.... Perhaps the tabs on the pads could be modified, bent, slightly for the clearance, cutting off is a bit radical and might make a pad change tricky. It's probably the pad whos tab isnt as angled. Vice and a bit of pressure carefull not to bend the pad face.
Presumably, as Tien says, the disc is running centered in the caliper.
Hey Gazza,
Common problem, same thing happened when I tried to use hayes calipers on hope 2 piece disks. Some caliper/pad combos come a bit 'low' for the spider.
So options as I see it are as mentioned above, trim the tab, ideally grind it so you don't put any bending stress on it, or hacksaw it off, and clean up with a file.
I went with a 1 piece rotor with the hayes brakes on my single speed, but you probably don't have that option with the centre lock mount.
...is your best bet for these. I worked a shop in the UK and this issue came up a bit. Get yourself a nice new flat-file, apply some elbow grease and walk away feeling like a real mechanic.
Nothing like a bit of home engineering to make you feel like you masculine!
this is 2009 mate! i wipped out the bench grinder and the first one was off in 20 seconds without even a sweat bead to be seen, the next snapped off when i was pulling at the pads to get them out! BINGO!!!
thanks for all the advice guys.
