Brake problems
I have a 77 corvette and I put new brake pads on. In the process i took the calipers off and cleaned them and put new hard lines on the rear. I put everything back together and went to bleed them and i cannot get fluid to the rear calipers. I can get fluid to the front and i can bleed the front and get the pedal hard until i start the vette and then the pedal goes soft again. I think it could be the differintal pressure switch, but i am not for sure. Could someone please help me on this. I've done everything i can think of. Thanks

I gravity bled mine and it worked fine. Make sure that the rear of the car is slightly lower than the front. Attach a clear hose to one bleed screw, open it and let it drain into a bottle. Let a decent amount of fluid drain out. Keep an eye on the amount of fluid in the master cylinder and keep it atleast half way full. Once you get good flow, close that bleed and do the other side. Once you have one side of the car complete, go to the other side.
If you do not get any fluid at all, there may be some type of obstruction. I would loosen the connection between the hose and the tubing to see if you get some brake fluid dripping their.
Good luck,
Dino

Takes FOREVER for fluid to get to the rear calipers, when any change is made. Speed bleeders help a lot, but still a lot of pumping.
I've heard good things aboyut the Motive pressure bleeder, but have never used one.
I had finally bled my brakes after replacing the long steel line to the back, the crossover steel line, and new flex hoses in the rear; literally thousands of pumps on the pedal (I was so bored, I was counting).
Then, a leak at my master cylinder, and replaced only the MC and the short line down to the distribution block -- hundreds more pumps later, just getting close now.
Hitting the master cylinder and calipers with a rubber mallet helps somewhat.
