    Are you sure? I think your existing M/C would fit.
    What makes you think you need to replace the servo?

    Servo test - pump pedal then keep your (left) foot on it.
    Start engine.
    Pedal should sink an inch or so.
    If not working could be lack of vacuum, but likely then the engine wouldn't be running well due to vac leak.
    If it's been apart, maybe one way valve is wrong way round.
    I only asked because I've fixed numerous servo problems and so far it's never been the actual servo itself.

    update

    ive just finished fitting the new brake servo WOW what a massive difference it has made ive got brakes like ive never had before im very happy

    servo is slightly smaller than the original but with there being a 270 pound differnce in price im not complaining

    original master cylinder bolted straight on

    time to fit it thou 6 hours :( this is only because ive got the red 9 design suspension so i had to drop it so i could get the old servo out
    van was just jacked up on the drive

    so im guessing there was something wrong with my old servo does anybody want it

    brakes are working rearly good i was going to put red nine front brakes on but i dont think i need to now
     
  16. Following this thread with interest, didn't even know there was a vacuum thingy! (not a clue about engines,learning a lot from here) just checked over my hoses and there is a split in the little rubber hose coming from the inlet that connects on to the braided hose, would this affect the brakes and the tickover?
    Does the length of the rubber bit matter? thinking of putting a bit of a longer one on to make reconnecting it a bit easier

    Where's the split? Can't understand from your description!
     
  18. On the inlet manifold there is a small length of rubber tubing which connects to the braided hose coming from the servo, there are two jubilee clips connecting it and the one on the braided hose side has cut/perished the rubber tube. Hope I haven't got the wrong bit, really pleased with mysel at finding it!

    Good spot, yes it would affect brakes and tickover.
