Has anyone else had problems fitting them in?

I was servicing my SC Blur, and decided to replace my pads (first time) but, with the pistons pushed all the way in, and the new pads fitted, the gap between them was nowhere near large enough to fit the disc.

I ended up refitting the old pads in, which still have life left in them, and there was plenty of gap.

Anyone?

Its possible the system is overfilled – try opening the bleed valve and see if the pistons will go back further.

Some aftermarket pads are two thick
