What brake fluid do people recommend for a seven, or do you need more info.

The best thing is to use what was recommended for the donor brake system. Our cars are very light and do not put heavy demands on the brake system. Racing is different.

Any Dot 4 fluid should be fine

Ordinary ester based D.o.T. 4 or D.o.T. 5.1


N.B. D.o.T. 5.1 not D.o.T.5

If you intend serious track use go for Dot5.1 but change it every year.

DOT4 is fine for road use, it is less hydroscopic so changing it every 2 years is more than enough.

Avoid competition fluids -- they are very hydroscopic really need changed twice per year they are also highly inflamble.

In general the higher the boiling point of the fluid the more hydroscopic it is and also more flamable --- brake fluid fires used to be very common in motorsport than can be very nasty because it burn very hot.

Thanks guys

had a google and think Dot 4 sounds OK.
