Abstract
In a vehicle having a brake line communicating a brake pressure to a brake, a lubrication control circuit controls flow of lubrication fluid to a brake cooling circuit. The lubrication control circuit includes a lube pressure control proportional valve and a shuttle valve. The lube pressure control valve communicates lube fluid to an inlet of the shuttle valve when lube pressure is above a threshold. When the brake is applied, brake pressure in a pilot line operates on the shuttle valve and the shuttle valve communicates lube fluid to the brake cooling circuit and blocks lube flow to other cooling or lube circuits.
