Robert,
thnx ! that's exactly what I was looking for. I'll order them. strange thing is that after going to autozone, advance auto parts and pep boys along with calling others in the area no one had even heard of these. and the brake shops denied there's even such a thing in existence !

Steve,
the work was all done at the lexus dealers. two to be exact that are in central jersey. but for diagnosis I've taken the car to alteast 10 different shops and paid them as well. with everyone ending up doing a bleed and then just saying they don't know what else to do !
