Front brake on the "new to me" PX is a disc brake. It has very little power as you start to grab the lever and then gets really really grabby suddenly. At speed it is just dangerous causing severe jerking, dive, and whatnot. Anyone know what to look at first to remedy and smooth it out? Bike is 2005 so fluid change seems like the obvious starting point?
(Had a Euro market PX200 a few years back and the disc on that was powerful but buttery smooth... that is my only frame of reference.)
