Folks

I was getting very little suction going to the servo from the brake vacuum pump. Put a gauge on it and it was reeading less the 10psi at idle and around 40 psi at 5Krpm (Not sure if thats norm?). Removed the pump but as its a sealed unit not sure how to tell ifs its functioning properly. Should the rod that's driven by the cam be easy to push in and out. My one is very hard and requies significant pressure to push in out out.

Cheers!

They are always very hard to push in and out. I don't know if the figures you give are good or not, unfortunately.
