grinding noise from back wheel

i tightened my chain today and now the back wheel seems to be grinding metal to metal around the disk and when i break (on back) it screeches. The wheel is aligned ok with markings on swingarm any ideas where ive gone wrong

thanks neil

have you checked your brake pads cos you could have knocked one when you loosened the wheel. Make sure all is tight but it doesnt sound good that.

If I remember right I didnt move the bolts with the marks next to them when i did mine. I think I adjusted with the allen screws on the back of the swingarm. If they arent adjusted equally the bolts on each side of the bike could be equal but the wheel could still be mis-alligned. I know that reads like crap but I know what Im trying to say! Oh and if its a break bad youl probably have scoring round the break disk.

i just took back wheel off and one of the pads has nothing left on it

im gonna fit some new pads now

thats a relief

thanks

good good nicely done!
