Right my 406 coupe has a problem.
The brakes are sticking on slightly , leaving the lights on also, the pedal doesn't fully return to the off position.
The guy that did the mot suggested I change the mc which had being done for a new unit and it made no difference.
If I disconnect the pipe that goes from the inlet manifold to servo then the issue go away but of course the pedal is very hard.
How can I test the one way valve and the servo??
