Pump the brakes several times and hold the pedal down, when the engine is started the pedal should move down farther if the booster is working.



Good point Rogerm60.

Ka, there's a plastic fitting on the brake booster. There's a check valve in that fitting.

With the car off slowly try to remove that fitting. It's not easy. You should hear a vacuum sound as you remove the fitting. If not - the check valve is bad. Otherwise maybe the booster has taken a crap.
