WE HAVE SEVERAL THINGS GOING HERE THAT COULD FACTOR IN
.........LIKE IS YOUR BLEEDING TECHNIQUE EFFECTIVE? IS IT CORRECT?
MASTER CYLINDER....DID YOU BENCH BLEED IT?
ARE YOUR REAR DRUM BRAKES ASSEMBLED RIGHT............AND ARE THEY ADJUSTED SO THAT THE DRUM AND SHOES ALMOST TOUCH (OR EVEN SLIGHTLY SCUFF WHEN ROTATED?
IF YOUR REAR SHOES HAVE A PRIMARY AND SECONDARY SHOE (LENGTH OF LININGS) YOU HAVE SHORT ONE TO THE FRONT (ON EITHER SIDE OF THE VEHICLE) AND A LONG LINING TO THE REAR (ON EITHER SIDE) ????.............NOT 2 SHORTS ON ONE SIDE...2 LONGS ON THE OTHER....OR THE LONG ONES TO THE FRONT, SHORT TO THE REAR......
THE "HISS" MAY VERY WELL BE THE BOOSTER.......CONFIRM THIS UNDER THE HOOD OR DOWN IN THE FLOORBOARD WHILE THE VEHICLE IS IN "PARK", THE ENGINE IS RUNNING, AND YOU DEPRESS THE BRAKE PEDAL..........CHECK THE VACUUM LINE GOING IN TO MAKE SURE IT IS NOT LOOSE OR BROKEN
THIS IS THE WAY I DO 'EM.....SEE MY ANSWER IN THIS LINK

I SORTA HAVE TO APPROACH THINGS IN THIS WAY.....YOU MAY "MECHANIC" BETTER THAN I,.......... BUT SO MANY DO NOT EVEN HAVE A CLUE THAT "BRAKE FLUID" GOES IN THEIR CAR......I TRY TO COVER ALL OF THE BASES I CAN!
DOES ANY OF THIS HELP YOU ?
