QuestionI understand the bleeding principal. Pepboys bled it, Midas Bled it, I bled it, I have put about 3 quarts of bake fluid through it. Fluid is running cleaner than a brand new car. Brake is there, just spongy, and then after a while, 3 weeks or so, it just fades away. then I have to rebleed the system a little to get the air back out. Like I said, I can't find any leaks,and There is no fluid loss.

Brake question on a 77 Vette. air in lines. I have replaced the master cylinder twice, I have taken the car in for repair, they replaced the left rear caliper, and said I needed to replace the front calipers as well. The problem is, I'm not getting any air in the front when bleeding. But, the rear continues to get air. when I bleed the rear, I get brakes back. Still Spongy though.
not a nice firm pedal but enough to stop the car ok. No leaks in the system that I can see. I'm trying figure out what the Problem is. Since the Brake repair shop couldn't figure it out.

DAVE;
HI if you can get a air tank with the brake fluid in it,than it will be easy to do, if not you will have to fill the master cyld. every time you bleed a wheel. start fron the r/r than l/r than r/f thanl/f and each time you get out some fluid add more keep it full at all times. than bleed the master cyld a few times also than start all over r/r,l/r,r/f,l/f/ and mast.cyld.do it till you get a good pedal. it will take time but you will get it but make shure you have no loose bleeders or lines ok. some times you will get a bitch job, and it will take time, p.s. do you have power asst brakes? if yes you must keep the car running OK ....

Answer DAVE;
ok well if you have looked all over and you can not find any break fluid dripping, not any from the rear cylds. or front calip. than you say the lines are all good, not wet any place, than I hope that the fluid is not going into the power air booster and it might be a bit wet at the brake master cyld. rod. check that out. ok
