The May Car magazine has an interesting "Case study" article about a guy who put DOT5 brake fluid in a Mazda 626. His thinking was that it's expensive and used by racing drivers, so it must be good stuff. Seems like he kept on having problems with spongy brakes afterwards.
To fix the problem, the mechanics bled the brake system, cleaned it and replaced the DOT5 with DOT4. It turns out that DOT5 lacks some properties needed for normal road driving - stuff like water absorbing properties, viscosity, anti-bubble, etc.
Anyway, my point is, to all our friends that wrench on their own bikes, make sure you understand what the manufacturer (maybe not the dealer) recommends as a replacement fluid/oil. It should be correct.
