I changed the rear pads and now my caliper is pressing very unevenly and I have no feel in the pedal. I tried bleeding it some and both pistons extend but it won’t put enough pressure on the rotor to have pedal feel. Rear piston/pad made enough contact to blue/burn the pads concentrated pressure I guess. When you press the pedal you can see the piston cone out a bit and goes back in. Could it be more air? My master cylinder? Any help is awesome thanks.
