I installed 95 GSR brakes front and rear, I am uncertain what Master Cylander and Proportioning Valve I am suspose to use for these brakes to perform perfectly without the use of ABS.....the f.a.q. doesnt have much imformation or replies to the topic.....

 

You can use a 4040 prop valve from a 90-93 Integra or 94-95 Integra RS. You can use a 15/16" master cylinder from a 90-91 Civic EX or a 15/16" master cylinder + brake booster from a 94-95 Integra RS.
