By the way, there is minimal dfference between DOT3 and DOT4 brake fluid. They are both glycol based fluids and can be mixed in a pinch. The only real contamination would be having the ATF fluid in there. DOT5 is where the fluid changes completely to a silicon base and is not compatable with the earlier spec fluids. And no, you do not want to use DOT5 fluid. -- -Fred W
