just in the process of modifying my brake setup,brought adjustable proportioning valve,and 1 residual preasure valve(2lb).i was just wondering if the residual preasure valve needs to go before or after the proportioning valve(rear disc)and also do i only need the 1 residual preasure valve(rear)or should i also put 1 on the front too(standard hilux calipers)
?thanks.
