I am having problems getting the brakes to bleed on my big six. It has Boxster calipers, a 23mm master cylinder, and no proportioning valve. I can't seem to get a pedal. After about 3 pumps of the pedal, it comes up and there is decent pressure. But the minute you let off completely, it will go to the floor the next time the pedal is depressed. I have put over 2 liters of fluid through the system already, using both a power bleeder and Betty's right leg. Fluid is ATE Dot4 gold.
This is the same setup I ran on it for years. It has always had good pedal, no issues with bleeding it either. Anyone got any suggestions on what might be wrong? |

You are using both bleed nipples (inner and outer) on the Boxster calipers I assume? Also - the rear brake lines have a "high spot" with standard pipe routing that just wants to trap air - even with no proportioning valve. Some creative angling of the car with jacks/axle stands can sometimes help when bleeding - good luck
