Ask a Automotive Brake Engineer

Just a post to answer any Braking systems questions or general automotive industry questions.
I have a lot of experience in Sensors and their manufacture as well.

When will we have "wet" disk brakes on cars?

Fluid cooled brakes, usually oil, are heavy, require a complete cooling system, and are very fuel inefficient due to the constant and considerable fluid drag on the stationary vanes. They are more suited to dirty environments because they are self-contained. I don't think they could handle the high thermal conversion of a high speed stop, the designs I read on the web would explode under a racing stop. Our Japan heavy industries division probably has some fluid cooled brake designs, but I've never pulled up the prints as I'd just be fishing to find it on our system since there is no "search key" term to find fluid cooled brakes."
