There is a reason for them and the FSM does a decent job of explaining why.
iagree
The residual valves are suppose to hold 10+ Lbs. of line pressure on all 4 wheel drum brakes is not needed on disc brakes, hence the factory removing them from the factory disc brake master cylinders scope
No residual pressure on the disc brakes will extend brake puck life and slightly increase your fuel mileage also, not a bunch though tsk Maybe .2 to .5 MPG scope
The idea of any car maker using parts not needed, like proportioning valves, is ridiculous down haha
you need to correct those items and enjoy the results twocents up scope
