Padgett Posted June 7, 2016 Report Share Posted June 7, 2016 Dual front with single rear (three pipes) or dual both ends (four pipes) ? Quote Link to comment Share on other sites More sharing options...
Imp558 Posted June 7, 2016 Report Share Posted June 7, 2016 All I know is there are four holes on the master cylinder that is not ABS. I'm assuming the front two go to the front wheels, the third one goes to a proportioning valve or something of a splitter for the rear two wheels and the fourth hole is for the brake pressure switch for the indicator light. That's all speculation though because I haven't seen anything in print.. Kind of hoping to find a car at a wrecking yard or at the meet to look at.

Padgett Posted June 7, 2016 Report Share Posted June 7, 2016 (edited) If only one rear pipe then need to block off the fourth fitting, switch usually goes in a proportioning valve. Ones I have seen, the first two are the individual fronts and the rear goes closest to the firewall. I have seen both a single rear pipe and duals. I have also seen brakes with just two usually split front and rear, rear is usually larger. So it really depends on the donor master cylinder.

I'll post a Thread about it and give you credit for it when I get this done the end of summer. Chris is right I shouldn't have brought it up in this thread.
