Brakes not working on my 68
I need some help. Just changed my 68 MC and new front calipers. Previously, my pedal was going to the floor, and some fluid from the right front caliper.... so, I changed the whole thing (MC and new front calipers with SS sleeves). I bench bled the MC, installed it with the new front calipers. But, cannot get my pedal to not go to the floor. I bled the right rear (no air in the line, just s olid stream of fluid), then the left rear and again no air in the line, just a solid stream of fluid. I went to the right front, and it spurted for some time as I opened the bleeder, then had the pedal pressed down, held the pedal down, tightened the bleeder, released the pedal, and did the process again and again. The pedal seems to get stiffer, but still goes to the floor. After having very little spurting from the right front, I went and did the left front. Same process as I outlined above. Lots of spurting and not a solid stream of fluid yet. I would expect we have did this process at least 100 times and still the pedal goes to the floor. This was all done with the engine off. I then started the engine and the pedal just goes to the floor.... like nothing is there.
Any suggestions....???? I did not try gravity bleeding... but thought maybe I am doing something really out of order here. Would appreciate some help.... I hate to take it to a brake shop... but am getting concerned about getting this job done. When I do open up the bleeder with pedal up (before I press the pedal down), you can hear it suck air just as it opens... Maybe I have something simple, but maybe not.
