Hi,

first post on this site!

using a 1.8d endura mk4 fiesta(1996 n reg) as a runaround.
the other day my brakes pedal went hard and the brakes hardly work now.
no noise coming from them.
the haynes manual suggests that it could be the servo or vacuum pump.
when the engine is off the brake pedal stays hard. I have depressed the pedal when off and the pedal does not move/give in when I start the ignition.



Just wondering if anybody knows how I can check if it is the servo or the pump that is faulty.

I can see used servos on ebay for mk 4 petrol engines -
can I use any mk4 servo? or is the diesel one specific?



thanks
