I had some stalling (no idle) on my '71 bus. with a '78 front end. it would idle when I plugged the vacuum line to the servo. How do you check for leaks in the servo?
oh, no another T-2 power brake q.

take a wheel valve and insert it in the hose going into the intake manifold. I use a clamp to make sure its sealed. then put about 20 pounds of air, check this with tire gage. Let set for a few hours and check to see if you have any pressure still in the system.

You could probably simply suck on the vac line. I would do the check right at the servo to eliminate hose leaks before condemning the servo. Those hoses tend to get stiff and don't seal well.
There is a check valve in the line which could affect testing, just so you know.
