Thanks for your reply. What a coincedence. But it seems strange that after we did the same work, our boosters quit.Maybe I`m not convinced because before I parked the car to do the work, the problem was that the RF rotor was metal to metal with the pads and I decided to do the whole gig.There wasn`t any excessive pedal travel or `sinking` that I recall. Anyway I just checked FCPGroton and they want $155 for a new servo (since you didn`t have much luck at the boneyard).Also I`ll check the valve even though it,the grommet and hose are fairly new. Let me know on this thread what other insights you get while finishing yours. Thanks JS
