By the way, the shuttle valve does nothing for safety other than turn the dash light on when the brake pressures are unequal (front to rear and before the p-valve). This is totally unnecessary since you will immediately know (by brake feel) that there is a problem with either the front or the rear brakes if that situation were to occur.
