this might be a strange question but, does anyone know how the brake fluid transfers from one side of the STi Brembo calipers to the other? i was just inspecting my buddies EVO and the Brembos' on his car has a small fluid transfer tube across one end of the caliper for what i'm assuming serves the purpose of transfering the pressure across the caliper to the pots.

is there some internal fluid transfer port within the two halves of the caliper on our cars? would it be benificial to outfit the calipers w/ an external transfer line, there are just plugs on the STi calipers where the line might go. i know the fluid transfers across to the outer set of pots, from the various times i've bled my brakes, but does anyone know how our setup works????

The STi calipers have an internal crossover tube for that purpose. Some of the other factory Brembo equipped cars have external crossover tubes like most aftermarket big brake kit calipers.

The real deal would be to connect the bleeder ports to an external crossover tube and have ONE bleeder nipple. That'd be a great time saver when needing to bleed the brakes of any air/boiled fluid during track days.
That would be just dandy.
Be good,
