Hello, i have Quad QHD 4 axis hydraulic brakes. I recently fitted some new pads. They are magura ones and they fit ok however they seem to rub. I have pushed them further in so they don't rub on the disc however as soon as i press the brake they move back and rub again, is there any way i can fix this? I had them bled at a local bike shop a month or two ago, but do i need to do it again to solve this?
