Test for booster:- Engine stopped for some time, apply brakes several times, hard. Hold brake pedal hard down, start engine; pedal should go down further as engine starts. If it doesn't, no boost, probably no vacuum to the booster, but internal problems could stop it working, as could a blocked breather - not sure where this is, never had to worry about it, but it will be somewhere on the booster, probably with a gauze filter.

While I agree its unlikely, conventional brake fluid though is hygroscopic and will absorb water, this will then boil at a lower temp giving a soft pedal like air in the system.

20 bucks its a cracked booster;)
No discovery yet, but I've paid the tax , so wont be long( I keep saying that)
the trip along the beach sounds good, even the wife said it sounds good.( her and off roading don't really mix).
cheers

Place your bets gentleman on the Dawgs brake upset, we have Rich at $20 for a cracked booster, JDNSW??:D:D:D

I tried the press brake and start trick and it did sink when the engine kicked over....but like I said come Saturday and I will sort it out whilst I install my new headlights that took 3 weeks to get here:mad: and they forgot to send the Xenon globes:twisted:..
Rich, the beach will be a goer, I will take my lot aswell in our Disco.

:twobeers:FWIW the vacuum pump failed on my 95 300tdi . Intermittent symtoms as you
have described before total boost failure. They are a sealed unit and not cheap.
I hope it's something else.

Well, I checked all the things you guys said today and completely changed the fluid..and presto the fliud change has made a 80% improvement.. Thanks for all your valuable imput and help made the check list easier.:)
But now I want drilled/slotted discs and that new drum/handbrake conversion..where will it end:cool:
