If you are, you center it by opening the oposite bleeder, and that will allow it to move back to the center position, and put the light out.
yep, that's what I'm talking about, I'm not shure if mine is a preassure differential switch or a combination valve of sorts ( a true combination valve would have all nessary brake valving in which mine does not because both RPV's are supposto be built into the MC ) , which would be both switches in the same thing, but I'm guessing it's a proportioning valve also. Thanks for the help, do I just open the bleeder and have someone push it to the floor or do normal bleeding procedure and have preassure applied to the pedal b4 opening the bleeder?
