No, the only part you are gutting is the residual pressure valve and proportioning valve, that's what the plug is for. You still retain the differential pressure valve and metering valve. Residual pressure valve is what saves your but if a brake line breaks or leaks, leaving the other half of the system functioning. The metering portion allows the rear brakes to gain pressure before allowing pressure to apply to the front. Don't remove it. Just gut the non adjustable proportionong valve. Whole job should cost less than 100 bucks to do. Give me a call and save me a lot of typing.
