did you prime the master cylinder?  Normally we just bleed them with one person pushing down the pedel and cracking the bleed screw.  Then closing it and lifting the pedel.  is there anything that could clog the rubber lines coming from the resevoir to the master cylinder?

Just throwing some ideas out

Calipers?  Do you have your old caliper's? if so just try and swap them out.

as always check the pads and make sure they are seated. Then double check them because they will cause you to do a lot of unnecessary work.

What Scott said.

I know it sounds like you have checked all this... Slow down....  check it again. At least it doesn't cost you money.
I am thinking that your master cylinder is not bled properly or you may have an air leak somewhere in the fittings.
My thoughts for what you think they are worth.

1)keep bleeding, the steel vw stock master comes with instructions thar tell you NOT to bench bleed the master.
2)Make darn sure a pad is not out of place.
3)Tighten the rear sheos until they are almost locked and bleed in that position.

Let us know where this is going and how your brakes work. Or, the solution that you come up with. It is so hard to diagnose problems when you can't put your own touch or feel to it. Best Wishes!

Thanks,

do both cars have the same master? As is steel vs aluminum? Make sure the pedal rod is adjusted properly.

Make sure the new wheel cylinders are installed correctly. A customer brought his car last Friday and he was having similar issues. All new hydraulic brake parts, over the counter from a O'Rielly's. First issue, M/C leaking into car at seal. Replaced with another one under warranty.

Second issue, he had two different size wheel cylinders. Changed those to match and everything worked fine.

Look at the small stuff.

Yes both cars same steel master by the way I think they are a horrible choice  how would you recommend adjusting the master push rod as it does have  a little free play before it engages thanks again for everyone's advice

when you say you (pressure bled the front) is that with a vac bleeder if so i had one heck of a time bleeding the brakes  when i replaced every thing in the system. what worked for me was to put the vac bleeder on the right rear wheel ( because it is the farthest from the master ) turn the vac bleeder on and pump the brake pedal at the same time. then the same on the left rear then the right front then the left front. the pedal was good but a little spungy. so i bleed it bye pushing the pedal down and cracking it open, closing it and letting the pedal up. and now the pedal is great. good luck

The left rear is the farthest if you look at how they are plumed. I would do it from both rears though because of the T fitting.

I just do both one at a time. I just keep it simple and bleed all corners until there is no more air and have never had a problem other than the brake pad getting out a little and make me chase my tail for a while.......... ;)
