Is there supposed to be a one-way check valve on the vacuum hose between the vacuum block and brake cylinder assembly? Trying to solve an intermittent squishy brake problem.

I see. I'll check to see if it is working properly. Thanks. The vacuum line looks good. The brakes seem to almost go out at high idle until it warms up or just getting out of boost sometimes.
Isn't that one of the complaints about vacuum brakes on a turbocharged Regal? I'd wonder about the check valve also since it could be bleeding vacuum out of the reservoir, perhaps even more so under boost.
