Does the rabs valve have the proportioning valve built in? The residual valve? In other words, does bypassing the pos cause any problems??
On my 1994 F250 4x4 the proportioning valve is attached to the master cylinder. I don't know if the rabs valve performs any similar function. I have not had any problems after bypassing the unit.
