Vaccum Pump Pressure, Tdci


Recommended Posts

Hi Guys and GIrls,

Does anyone know how much pressure should the brake vaccum pump should produce on a Ford Focus TDCI, i'm experiencing major issues with the servo assist brakes, mega hard pedal and limited braking, changed the brake master servo, one way valve, brake hoses and serviced all for calipers. My only thought now! is the vaccum pump producing the correct amount of pressure to assist the servo, there is a little amount of pressure though.

Kind regards

Finally found the pressure of the pump! for future reference it must be at least 500mm HG, anything less than this then the pump is faulty, looks like i need to look elsewhere as mine is about 600mm HG.

Kind regads
