guys, im desperate.

alright, i have a new master cylinder and 4 new calipers, new pads also.

when i push the pedal in slowly, it goes to the floor, when i stab it, there is a lot of tension on the brakes, they slow down good, but still not like they were with the old calipers and master cylinder.

any ideas?

Try the drain em over night method. Open the master cylinder and fill it. Open all 4 caliper drains so that they drip. Refill MC after 6 hours. Let drip while you sleep. Next morning stop drip, fill and close MC and try brakes. This has worked for me when normal bleeding didn't.

Vette brakes are buggers to bleed. I use both a vacuum pump and gravity, I elevate the end of the car I'm bleeding, and I make sure I bleed in the order specified in the service manual. Also helps to tap the calipers lightly with a wrench or something to dislodge any bubbles.

bled the m/c, ill try the drip bleed method, nothing to lose

Gravity bleeding works good. Keep the master cyl lid off during gravity bleeding. Do not let the mast cyl run dry or you need to start over. Loosen the bleeders one at a time. I loosen mine two full turns and go make a sandwich. Come back and its flowin good. Cinch it up and move to the next. It takes a while for it to come thru sometimes but it eventually will. Thats why it helps when gravity bleeding to loosen the bleeders real good. Heck, you can even remove them completely if its air locked real bad. once it starts flowin screw the bleeder bacK in and allow to bleed till yur confident the air is out of that line.
