Noticed what appears to be break fluid on foot well under pedals in my TR6. There was a drip hanging on the rubber dust cover located on the brake pedal side. Released the pin connecting the brake pedal, removed the rubber dust cover, removed what they call the retaining ring, but found no filter. First, would the filter not being there cause brake fluid to be dripping? Second, if so, does anyone know the size, thickness, what have you of the foam filter that is supposed to be there. I will spend the 30 bucks if need be for a new filter...however I have read of guys making there own from lawn mower foam filters.
