sorry for getting back late, but yes its a pressure switch in the line mounted just behind the triple tree. I figure a good flush of all the fluid would fix that, so if im going to flush might as well do the whole brake because it does squeak if im just lightly using the front brake, to slow myself, but if i GRIP the front brake, there is no squeals at all.
So should i just "de-glaze" the rotor with sandpaper by hand in a swirling motion or should i use a palm sander?
I still have the stock rubber hosing and don't think i should change it unless its cracking... but was does a braided line run for the R65?
