Brake problem, cant stop.

Edge:

--- Quote from: "Hangover" ---Pull the vacuum pipe off the brake servo unit,with the engine running stick your thumb over the end and it should suck,if it don't then the vac pump or pipe work is the problem,if it sucks then put it back and listen out for any hissing noise around the servo area.

Another way ive found "hope this is useful":-

Press brake pedal repeatedly (with engine off), until pressure builds up. Keeping foot pressed on pedal....start engine. If pedal sinks the vacuum pump is working.
