Hi RC,

I bet it's your hydraulic pump...my mechanic said that it was due to the
pressure not building up automatically from the hydraulic accumulator or
"bomb"...does your "brake" light stay on for longer than 15 seconds??  (This
is all based on my Coupe's diagnosis)

Do I get the dinner??    :-))
