I replaced the 2 lines from master back to coupling going to rear calipers thiss weekend. I replaced both calipers in the back. I made it so the bleeder valve faces the ground. Is this ok to do? Put steel braided lines on the front calipers. we bleed the system many times. we have fluid comming out of all calipers. NO LEAKS. but my pedal still goes to the floor. I took it for a spin and when I pump the brakes to stop it gets better. when it does stop the pedal goes right back to the floor. Is there a bleeder valve around the master cylinder? I am not sure what else to check. Starting to get to cold to keep riding my motorcycle. please help.
