Quite a fascinating topic! It would be quite a coup if some DSC member could design an improved rear brake. So many ideas have been mooted: the fluid overheating, not enough fluid in the system, relocating the master cylinder, Aprillia calipers, leaking bleed nipples etc etc. I guess many of them are partial causes. I certainly think Go Falfer could be on to something about the nipples. They always seem to weep a few bubbles in the tube when I connect the mityvac to them. But then, I can't be sure it's not leaking into the tube past the outside of the nipple from the atmosphere. At least, that's what I assumed before. |
