brake servo vacuum hose hiss?
Removed the vac hose from the servo end when removing UIM, as the other end of the hose didn't want to come off. It made a hissing noise as I disconnected it, pressure escaping I guess. Do I need to do anything special other than refit and start the engine as normal?

Re: brake servo vacuum hose hiss?
The hiss would have been vacuum, e.g air going in not coming out.
There's a non-return valve to hold vacuum in the servo.
When you restart the engine, give the throttle some light blips before driving, so the vacuum can accumulate and ensure that you have fully working brakes.
