Ok got a combination of mono-mini and m4 on my bike, Rear brake jammed solid yesterday and the Front M4 wasn't returnig properly. Been commuting onth bike so there has been some salt build-up so cleaned evrything yesterday. Took the pads out, pumped the brakes to get the pistons further out and lubed them with brake fluid. Everything seemed to be moving freely enough but they're still dragging today, any help greatly appreciated.

Have a look and see if it's just one pad touching the disc or both. If it's just one, get hold of the disc on each side of the caliper and shove it over a bit towards the side that's rubbing and get someone to pull the lever as you do so. That should reset the pads to the disc. Might take a couple of tries to get it central. If it's both, try either pumping the lever loads to reset the pads, clean and lube lever pivots or try lubing the seals with brake fluid again? Otherwise it could be too much fluid in there if you've bled them recently and not pressed the pistons back in before you bled them.

Look here http://www.hopegb.com/page_mep_force_38.html should sort you out.

Reset the pads as in the hope vid referred to above. Set the calliper central then reset the pads
