Ron, I think its due to the brake line being above the caliper and 
unless the system is vacuum bled
it never removes all the air and it eventually rises to the top. Once I 
did my SS properly it was good
until I sold it a year later. My current ride is a St 2 and the caliper 
is above the rotor and it has never
had a problem like the SS did.
