Yup, don't go changing stuff until you start with the proportioning valve and go from there.SSN696, if the question regarding foot pedal or hand brake, my 87 EC has an e'brake foot pedal.
Abbey, thanks for sharing feedback and your experience. I'll likely do just the prop valve alone first and, if necessary, add the adjustable valve later.
I respectfully disagree with this only because some of the needed information is not included. There is a difference between an S10 and C5/C6 and Z06 caliper fluid capacities. I agree that an S10 front caliper will work with a stock master and a proportioning valve swap is recommended. But that same master cylinder will apply a C5/C6 brake about 2" from the floor. and the stock proportioning valve will work fine with a metric rear caliper upgrade only because the proportion of fluid needed between the front and rears is very similar to the stock brakes if a larger bore master cylinder is used.Yup, don't go changing stuff until you start with the proportioning valve and go from there.
