Just a weird weird deal.


I don't hate it. All clean, fresh parts, street car, nice paint you're afraid to get messed up...maybe an OK option.

But it doesn't absorb water, which means moisture can puddle and corrode in the system. And it is compressible. And it can be hard to bleed. And mixing it is asking for trouble.

Race cars, I'm using a good, synthetic DOT 4, and I'm maintaining/flushing the system through once in awhile, keeping the pads fresh, resealing calipers when they need it.


If the results don't match the theory, change the theory.
