Thanks Dave for the reassurance.

Tony, we have been going to the same place for over 20 years, when property prices bombed five years ago we bought a superb cottage for a pittance. Just hoping Brexit will not spoil our fun.

Three years ago I found two SP250's and a V8 250 in a barn just 10 miles away from our cottage but the chap wisely did not want to sell and still has them, along with a dozen other collectors cars all un-roadworthy but dry stored.

Well the info in the thread on the above link was very informative but I now don' t know what to put in my brakes when I eventually get that far .
I had convinced myself that DOT 5 was the way to go but now I don't know.
Has anybody on this forum got first hand experience or recommendations?

Nick

While reading the link and typing the post others have posted, I am now erring towards DOT 5
"Nick - do you think you will ever put that old car back together again?"

I still use Dot 3 for all purposes. It has better lubrication qualities than 4 or 5 and minimises the possibility of sticking seals which is a particular hazard in remote servos

As far as silicone fluids are concerned , whilst they are not hygroscopic in themselves, they do not prevent condensation in airspaces such as those in reservoirs and master cylinders . The result is that water globules can collect and run down to the lowest part of the system, where the water settles and gradually rusts/corrodes the metal parts . Thus a change of fluid periodically, with complete flushing of the system with e.g. alcohol, is still advisable

Turned out in the end that the clutch slave cylinder had let water in under the outer seal. The piston is rusted into the cylinder, it had gone down with the extra pressure I put on the pedal then stuck wide open with the clutch disengaged.

The tell tale was that I could select gears, even with the engine running.

Did a bit more research on the subject of fluid types and came up with this extremely detailed explanation of barke and clutch fluids, some interesting myth busting http://www.mossmotoring.com/brake-fluid ... tish-cars/

Just as a matter of interest, the new slave cylinder arrived today from SNG Barratt and in very small lettering on the box it says, "not suitable for use with mineral fluids"
