Where is vacuum motor?

If anyone can show me a pic of one fitted I'd be grateful.

Seems the td and tdi are different.

Rick seems to think below injector pump? For the tdi too?

I'm.gonna strip.bash plate and a magic perished hose will immediately show itself...

Heeeeelllp

Not got any pics but mine is just under the injector pump.
Follow the hose from the servo,mine goes across back of engine,then down towards alternator where it tees off.one pipe goes under engine to vac pump and the other up to actuater thingy on inner wing under air box.
Check all the rubber sections for splits.

Some did have the vac pump on the back of the alternator but I think that was the earlier td engine

Any more tests I can do?

I have checked the one way valve in the servo by sucks and blowing (ooh err)

it will allow you to suck but resistance if blowing.

I have disconnected the hose off of it turned the engine on and it sucks my thumb, when I turn he engine off it looses the suction.

I have checked for visual leaks or cracks as far as I can trace to the muddy bottom

The 3 solenoid things underneath the airbox had an air hose running to two of them (off the main hose) one of them as completely disconnected

Still no difference, pedal is solid.

Someone from my work asked if the Terrano has a vacuum reserve reservoir

so you have vacuum! the vac reservoir is in the Lucas servo unit, did the brake fluid test on the servo/cylinder joint reveal anything, if not then probably your servo has failed, I have several here, Rick

No could not see any fluid enter the gap (metal on metal) with the two bolts.

Any other tests I can do to confirm?
