In most factory applications the residual valves are a component in the master cylinder. Likely the residual valves would be as close to the master as practical. If you purchased an aftermarket kit the lines from the master to the proportioning valve are already formed and everything fits nicely with the mount bracket. In that instance it might be better to locate the residual valves in the lines aft of the prop valve. I have seen them both ways and have not heard of any problems. Many of the aftermarket suppliers build the residual valves into the system specific to your application therefore separate valves are not necessary.
