I went to a double mc and stayed with drums and had to add 10lbs residual check valves. I added one to the front line and one to the rearclose to the mc. I was told to add 2 on the front line after the split and then add a proportion valve but I didn’t go that route. They work great now, before the check valves I couldn’t get any pressure from the pedal. Now it’s good and firm.
