Looking for pointers on adjusting the pistons on the Formula C1 hydraulic brakes. My problem is the brake pads are still rubbing agains the rear disc. I've had some moderate success trying to fix it, but there is still some rubbing. I have tried to reset the pistons but the problem is, when I push one piston back in, the other piston comes out slightly. I haven't found anything out there that addresses this. Sounds like I need to do some bleeding but I'd like to see if anyone has experienced this before. From what I've gathered, space between pads and disc are pretty narrow to begin with on Formula brakes.
