After serching the net for brake plumbing I have found about 10 different answers. I have a dual power master cyl mounted under the floor. I have dics fronts and drums rear. What I need to know in what order does the valves and switch go from the master cyl. Such as to the rear drums from the master cyl to a brake light switch to residual valve to adj. proportioning valve to drums or? and master cyl to residual valve to metering valve to disc?In this order ? What I have found on the net for the same setup is alot of different valve combinations.

Thanks Randy Brannon
