I guess I should clarify my statement. I ment that it was one of those
two object (air _or_ water) than DOT 5 didn't like to play with. I have
been corrected, that I should have stuck with the statement about DOT
3/4 being incompatible with DOT 5 and left it at that! <grin>
BTW, since we're on the subject of brakes, is anybody familiar with the
Hawk brake pads? The guy at my local race shop just loves them. I've
ordered a set to try. (it's _only_ $50 ;-] ) They sounded good at
least for aggressive street use and mild track. Coefficent/Friction of
.44, no-fade operating range of 100- ~1100 degrees F. Supposed to be
extremely rotor-friendly. We'll see about the dust however!
