Thank you very much vw rule! Now I have a few more ideas that we can try. We did try a bit with the engine running, but maybe not long enough. I notice you write that the fluid will only drip out the bleed nipples or not at all when the engine is of. I guess that means there is something wrong with the ABS unit if the flow does not increase after the ABS is done with it's check? I'll try some more with the engine running. And thank you again!

Thank you :-)

Put in new brake lines, yes, and tested them with air. The flow is good all the way from the master cylinder to the caliper. The problem is that there is no fluid comming out of the rear output on the master cylinder when it is installed in this car. Works good in the other car. A very strange problem...

Since my last post I have tried a few things, but the result is the same, no brake fluid going to the rear. AS mentioned in my first post, we traced the problem all the way to the master cylinder. We did this by first opening the line at the caliper, then before the compensator and then on the master cylinder. No fluid came out any of those places, and the brake pedal stayed “hard”. That led us to believe the problem was the master cylinder itself, so I got a “new” refurbished one. A couple of weekends ago the old one went out and the new one in, but the result is the same, no fluid comes out of the master cylinder for the rear… Talked to the shop I got the new master cylinder from, and they said the G60 cylinders are pretty complicated and it had to be “something electronic” that did not work. To be 100% sure, and since I have other G60’s with the same cylinder, we checked the master cylinder on one of the other cars. It worked perfectly with fluid going to the rear and everything. So earlier today we removed the cylinder that we know works perfectly over to the Corrado, and the result is the same as before… No fluid going to the rear. This leads me to believe that the brake shop is right, that it has to be “something electronic” in the corrado that does not work. Anybody have any idea at all what might be the problem? Everything that has to do with brakes is now new in the corrado, master cylinder, lines, hoses, calipers, pads and discs. But still no rear brakes.

Hi Paddy, thank you for your reply. Yes, by the “method of elimination” I first opened a line on a caliper, then the input on the brake bias valve, then on the “T-splitter” right before the valve, and finally on the master cylinder. Still the pedal does not go to the floor and no fluid is coming out. So I’m afraid you’re right, must be the master cylinder.

Hi. Sorry if my english is bad, but I'm not from an English speaking country. I had two Corrado's back in the 90's, so when this project G60 showed up in the right colors (Black with beige leather), I just had to get it. This weekend I changed the breaks. Lines, calipers, pads and discs. But when it came to bleeding the breaks I ran into a problem. There is no fluid going to the back. My bet would be the master cylinder, but I figured I'd check online if anybody have any experience with this. The break system in the Corrado was fairly complicated for its time, so maybe it has some safety features that I don't know about that disconnects the fluid from a circuit if it leaks badly or something like that? I loosened the rear break line directly on the master cylinder, but the break pedal was still hard and no fluid comming out. There is no battery in the car, so IF it has a safety feature like mentioned it might be something electronic? Anybody knows? Or should I just get a new master cylinder?
