Replaced the shoes, wheel cylinders, Master Cylinder and Power Braker Booster. Bleeding was completed with an air powered power brake bleeder. Now when you apply the brakes the damn thing whistles and spits brake fluid out from under the master cylinder cover. Where the heck did I go wrong?

Make sure the top is seating on the master cylinder good.it may have a factry flaw in it.Check it with a straight edge and if it's off take it back or use a file to level it but make sure you put a rag in the cylinder to keep shavings out

And make sure the rubber seal is good. Did you bleed the master before you did the rest of the brakes.

I'm concerned about how much pressure was applied by the pressure bleeder. If I remember correctly, they only need about 30 lbs to bleed the system. They will all spit fluid up into the reservoir, but I've never heard one whistle. Maybe the whistle is coming from the booster? I agree with knucklebuster, and nu2-72 about the cover and gasket seating squarely, and tightly.

Also check the little rubber grommet on the booster that could be the whistle

Thanks for the replys. I've never seen one or had any one tell me of one doing this before. I figured I just flat screwed up!!! Anyway, I hope to be under the hood tonight checking these issues out.
Thanks for the replys!!!
