hello thanks for taking the time to look at my thread..

firstly let me say this is my 1st bike with disc brakes so im unfamiliar with the set up.. ok so my problem is this when i apply my rear brake there is movement forward and back in the rear wheel however the disc does not move but the hub/wheel does how is this possible?? i dont have this problem with my front wheel.

bike is a CUBE ltd 2012 with deore hydraulic disc's

any help or advice gratefully appreciated

Your disc sounds like it's loose on the hub.

Get it to your bikeshop to fix the issue.

Iz you wheelz/hubz/rotorz Centerlock-type mount? If "yes", iz normal. You can't feel it when riding.

yes they are centerlock mount hubs/discs how come the front doesnt do it?

Then has the centre lock been checked? It still has a oversized nut on it.

But like said, if that's normal I know I wouldn't run them.

seems like its normal from what ive read which is a little disturbing but not the end of the world i had considered stronger wheels anyway so i'll be looking at standard 6 bolt fit hubs this time

sometimes on cheap brakes the pads in the caliber will be a bit loose and actually move back and forth a bit.

no its not the pads ive checked that from wot ive read its a common thing with centerlock rotors

Unfortunately that is a very common problem with centerlock rotors. Have your local bike shop run a check on them to make sure everything is torq'd up to specs though. Its more common on the back wheel also. Just like on v-brakes, if you apply both brakes, and roll your bike, the front will lock up, and the back will roll. Its because of the fact that on your front you body weight contributes to the pressing of the brake, downwards, over the center of the wheel, whereas on the back, your body weight is in the front of the wheel, letting it continue to roll forward.
Just the laws of motion man.

If you hate it, switch to 6 bolt iso calipers and hubs, and you wont have that problem.
