.......have fitted a dual circuit mastercylinder to my 60s pan ..sure i have heard you can "plug" a golf resivour directly into it ???.....Thanks

I used the original one no problems yet
I have heard that the golf one fits on as well but it would be a bitch to fill and check

Yes they are bitch to fill , usually requiring the removal of a wheel but you don't or shouldn't have to fill it each week anyway.
And the price of the blue fluid hose is well worth changing to the resiviore alone

I dont like the res in a major wet zone. Brake fluid is hydroscopic (absorbs water = BAD). Not to mention very awkward to check/fill !

Ive had the Golf one sitting on top onf the master cylinder on the Orange Smoothieeee for 5 years now
no problems with water or the like gets it out of the way and yes
the origional blue brake hose costs an arm n a leg for sure

i use a larger bore bugpack master with res on top on my 54 oval..no probs with water in the fluid,the car came in from the uk,it don't get wetter weather than that!...lol...

Fair enough guys. I hear what your saying re: water, but would you 'notice' water absorbtion in your brake fluid, or is it more a longevity issue for the brake components or a performance issue when brake component temperatures reach 100+ deg? All of a sudden when your peddling hard in a car, lets say like 2442TT, your doing 130 kmph down a nice country mountain road, late braking of course when .... I wouldn't like to expierence major brake fade or failure at a bummer time (especially in Ian's nice car).

Every vehicle is meant to have brake fluid flushed every 12 months for this reason.

Please come back with your opinions !!

yeah the secret is to flush every 12 months or so as per above

Depending on the master cylinder you buy, it may have different size grommets to the golf reservoir..
if thats the case, a volvo reservoir from the late 80's models, and many more, will do the trick for you. Just take the master to the local pick a part wreckers, and yank the reservoir out of a volvo.

Thanks for the replys one and all..another problem sorted on AVD..
