studioti Posted April 1, 2011 Share Posted April 1, 2011 I am looking for the Brake switch that sits right underneath the master cylinder. Haynes manual calls it "Dual circuit pressure differential switch". basically it sends brake fluid to the wheel cylinders and detects if there is a too much difference in pressure. if there is...then a piston inside slides to one side and completes the circuit to the switch turning on a bright red brake light inside the dash. if you have this i'd like it only, no master cylinder needed. i'd also like a stock proportioning valve that goes on the fire wall as well. all of these parts are for a 77 280z thanks Quote Link to comment Share on other sites More sharing options...
zedsn Posted April 1, 2011 Share Posted April 1, 2011 I have a proportioning valve for a 76 280. If that would work then let me know. Quote Link to comment Share on other sites More sharing options...
