i have just changed my master cylinder in my 89 vert..i thought it was easy..then i bled the brakes at all 4 corners in the proper order. it takes about 10-15 pumps for the pedal to get hard (when the car is off). I bench bled the master and i think it is not air bound. the pedal is just spongy it goes straight to the floor and the brakes barely even catch. i bled out the proportioning valve too and there is no air in there also...are there any adjustments that i missed?...any tips/solutions would be greatly apperciated..i have never done this before so provide me with some constructive critisism please!!!

 

looks like i fucked up on the bench bleeding process...i consulted a local car guru and that is what it looks like....delete this topic if you so wish admins...i got it fixed
