This echoes what MBM say about the RPV.

Another point to make is that brakes require 900 to 1100psi to make drum / disc brakes work effectively. An RPV with only 2-3psi really should not cause any break issues. As you say its primary function is to prevent bleed back which effectively pulls the wheel cylinders away from the shoes by gravity, making the initial brake pedal travel greater.
