I really can't see it being a servo problem.

Have you had the rear drums off yet?

Sounds like a sticky calliper ... Cos a stuck slider will give you 'brakes' but the as it shifts to allow the othe pad to come forward, you'll get a sudden slight pressure drop, which would show as the symptoms you describe.... Master cylinder seals would show as a steady lowering of the pedal when the pressure is held on as it creeps past the seals..... And there's now't worse than having something creep past ya seals....

Lez I put new pots sliders and dust covers on everfing seems to move good. And a new master.

sorry Moonshine that was me quoting Lez...LOL!

OK.....Is there a very minor leak somewhere , worth checking all union / flares etc...

It will be sommit stupid gaurenteed

It does sound like a ke a weep somewhere,corroded pipes etc..seems very odd.but,I can concur what lez says about the sliders.my brakes were binding on due to stuck sliders,I had permenant brake fade.now sorted I press the brake and get thrown forward...

Daz

so moonie what is happening now?

Am on the hunt for matches will have to be Sunday now and I have a proper mechanic he said last Satarday I aint goin away wifout anchors and there we were Jack had to stay the weekend at his place and Monday night had great pedal then started the engine I know what I just wont start the engine.

so the pedal goes when u start the engine???????????????????

Yes

Brake servo?

Daz

hows the vac to the booster

I reckon you may have a vacuum leak in the system somewhere

bingo

If you ain't got brake fluid leaking out and a drop in the level then as Chef says you must have a vac leak as the pressure loss can't be fluid

When engine is running I can get pressure by pumping again and now i can hold the pressure longer than before. When we were bleedin this time we felt the peddle only went so far and no more. Like the pressure was better than ever but it only brought the peddle so far and then no more improvment after that position.

I tend to agree, had a Merc G Wagen like that once if I remember correctly. Loss of pedal when engine on, didn't "feel" like a master cylinder gone bad.

Get one piece of vac pipe(long) and just try it on each section testing brakes as you go,It will the. Show the weak link replace it then your mobile, I would then just replace them all at a convenient time

What you mean the pipe pipes not the flexis. That is not a job I will manage there is to much straight cutting and thread worries. I can NORMALLY speakin manage most fings but thin pipes and threading. no can do, on. Sunday if it aint happenin then its goin to a specalist. Or the scrap heap I need to get on wif the other stuff.
