I opened the bleeder and kept squeezing the front brake 5-6 times. Quit a bit of fluid came out but it did not empty the resevoir. I closed the bleeder and tried again and no fluid would come out on either the left or right front caliper. I have a GS 911, which I tried to use following youtube videos, but it is only showing the brake pressure test no bleed the ABS. I did the pressure test and both the front and rear failed.What method of bleeding are you using?
