I posted this problem on the Spridget list, but as the problem is not
necessarily Sprite specific, I would appreciate your thoughts on it.
year I fitted new brake and clutch master cylinders and a new slave cylinder
on my Sprite and used Castrol Response Super Dot 4, Glycol based brake fluid
(available in the UK) in both clutch and braking systems . One year on the
fluid in the Clutch m/c turned dark grey and very thick and slave and m/c
rubbers failed. I replaced both Clutch m/c and slave and flushed system with
fresh fluid. After a month with new clutch master/slave cylinders the fluid
is turning grey again. The fluid in the brake m/c is fine. What's causing
the fluid to change colour and go thick, are the rubber seals disintegrating
or is the fluid oxidising the castings? And why the clutch system but not the
brake system as the m/c's were from the same manufacturer?
I called Castrol
Tech Support and they have not heard of this problem before, but have asked
for a sample of the fluid and old seals for analysis. I am also aware of two
other Sprite owners having the same problems.
