Just purchase some new uberbike floating roters stuck front 1 in no probs but the rear the piston I think arnt retracting enough I’ve tried the reset and also ‘re bled but the still rubbing on moving I’ve tried moving the caliper but still no joy

Some floating rotors are out of spec (incl. Hope). I suspect this thread has the wrong title 🙂

I see what you did, there…

So, to establish if it’s a caliper issue, options really are to eyeball the inside and see if the piston has retracted, try and fit a bleed block, or simply open the bleed nipple and try to push the pistons further in. Be careful, if this last one works you’ll have a small squirt of brake fluid in whatever direction the nipple is pointing. It’s possible the brakes have been bled with part used pads or otherwise overfilled?

I bled the brake last night with the block in I may just give the nipple a quarter turn and push piston back as much as I can and try That the front one went in no probs
