Thanks guys, yeah, I stayed with DOT3 in this car.

I switched our '65 Satellite over to DOT5 when I converted to two-circuit MC and the entire brake system was refreshed with new lines, brake cylinders, hoses.

Worry and hand wring about carbonic acid in the engine and won’t do the brakes?


up Yeah, this is where I have landed with almost all fluids.. A minor flush or refresh is a lot easier and cheaper than the deferred cost of excessive corrosion or repairing the damage.
Online information says that DOT3 will turn brown with age and increasing water content.
The seller of this car drove it regularly, but not far or long, over the past 4 years.
The brown brake fluid was probably older than that.
