Just changed my whole braking system in the front. My brake line on the left blew a hole and I replaced it. Decided to change calipers and hoses. Bled the lines. When the engine is started the pedal goes to the floor,any thoughts?
Did you let the master cylinder run dry during the caliper replacement? If so, you'll have to bench bleed the M/C. You may also have to perform an ABS bleed procedure.
After you installed the new caliper and pads, did you press the pedal several times with the engine OFF to move the caliper piston into contact with the pad? If not, do that now.
