Hi, firstly not sure if I should have posted this in the mountain biking > tech corner instead of here so please feel free to move it.
I have recently bought a new bike but my front disk brake is rubbing. The brake in question is a Hope mono M4 200mm hydrualic. It's a continous rub from one side of pads. Everything is new so should not be worn/warped/buckled etc
I've heard people comment on how disk brakes always rub/drag a little however this is actually making quite a lot of resistance when I try and ride, also the back one doesn't seem to rub at all. You can quite clearly see the disk is too far over one side - could do with going about .75mm to the left to make the disk central.
I've tried the trick with the playing cards which stops the rubbing nicely until I reapply the brake a couple of times resulting in it going back to normal, in this case - rubbing.
I'm new to disk brakes so am a little unsure of what adjustments I could try and make (if any) I have tried loosening the caliper and wiggling it more centrally on the disk but once tightened it reverts back to its original position. There's also a screw coming out the top of the caliper with a protective black rubber outing - but am not sure what this does.
I have taken it down the my lbs but they haven't fixed the problem ( I picked my bike up just before closing time so didn't stop to try it out)
Anyway any help would be much appreciated. Thanks, Nick.
