CooperMan, when I called Lichfield and spoke to Tom the other day, he gave two choices, the best being CASTROL SRF. I can’t remember the other. So Silicone based.
He did say that the improvement from the brake fluid was less than the pads. Given we have all had new fluid this summer, perhaps test to make sure it has not absorbed too much moisture. Assuming fluid within limits, just change pads.

Castrol SRF racing brake fluid conforms to DOT3 and DOT4 specification. But unless you want to operate your car under racing conditions why would you need such
