the pedal goes to the floor and I already changed and bleed master cylinder
I bleed the lines after changing master cylinder twice and it was good for a day.. now the pedal goes to the floor again?
Did you bench bleed the master cylinder first?
yes two different new master cylinders, checked for leaks in the lines, checked calipers, and the rear drums with no apparent leaks...
But did you bench bleed the master cylinders before installing?
This will need bled first with a computer like a snap on motus and then bleed all brakes.
