Hey, I'm having a bit of an issue with my shimano road ultegra hydraulics.
I'm changing my heavily worn pads and gone to fit new ones.
The Pistons won't go back in though. They sit out so that the worn pads and rotor fit, but with the new pads, there's no room for the rotor and it's a very tight squeeze to get even the pads in.
How can I get the Pistons back in? This was meant to be a 5 minute job. Ive tried pushing them in with a screwdriver and even bled the system now thinking, no fluid, no pressure to hold the Pistons.
