Editing Proportioning and combination valves

{{develop}} ==Overview== The combination or "combo" valve is a device that contains a warning light switch to show if there is an imbalance between brake system hydraulic circuits, and it divides the brake system into separate circuits- either front to rear, side to side or diagonally. It may also contain a proportioning valve.
