Ever wonder where it is?Its nearly impossible to access it without lifting or removing the tail section.It's easy to remove.I changed to dot 5 in my clutch and front and rear brakes.Flushed out first with denatured alcohol. I also changed the clutch to kevlar with heavy duty springs and I got a slave cylinder support bracket.Bit all this time I thought the front brake resoviur took care of the rear brakes too.
