Hi folks does anyone know if a 200tdi & 300tdi vac pump are the same :-k i think mine is on the way out :roll:
-
What year is yours and is it a 200 or 300tdi?
Part Number : NTC4991 - BRAKE MASTER CYLINDER DISCO TO 1994. RRC - 1986 TO 1994
Part Number : STC1285 - BRAKE MASTER CYL NON ABS DISCO 1 1994 ON
They don't list anything different, so one can assume that the parts are the same and as above.

Sorry :roll: :oops: it's a 95 300tdi with ABS
-
One thing you may want to check. is there a small hose coming out of the back of the master cylinder?
Going through a t piece, check see of the hose is split on the join, this is a favourite for brake probs
-
He Said VAC PUMP!!!! NOT master cylinder, and i can say 100% 200 and 300 tdi vac pumps are not the same,
Part No. ERR3539 300 TDI vac pump hope that helps
-
Hmm been :-k could i just have an air leak from the servo or pump/pipes thats causing my problem
i can pull up to a stand still after a run no problem with full sevo power but if i move off again and stop straight away like in traffic the pedal is hard :shock: but give it a good rev and i then have power again :?
-
Can you hear an air leak in side the car? could be a weak pump, as the end plate on 300 vac pumps are rivited on and tend to work loose, check your pipe work for leaks,
-
I cant hear anything inside :-$ i will have a closer look at the pipes tomorrow.
could be a weak pump
that was what i was thinking
i was very kindly ;) sent this link http://www.the4wdzone.com/vacuumpumpfix.htm i think it got to be worth a go :)

I use nice stainless allen key bolts, tap out the vac pump body with an M6 tap, job done, looks very neat,

Sounds like a lot of work just to get it covered in mud :D

where it read master cylinder was meant to read servo unit, brain firing on two cylinder at this time of day
