The disclosure relates, in one aspect, to a friction brake cooling system for a machine. The cooling system includes at least one pump connected to at least one reservoir containing cooling fluid. A controller is configured to divert a cooling fluid flow through a valve to a first friction brake system and to a second friction brake system based on the use of the systems. In another aspect, the disclosure relates to a method of cooling a first friction brake system and a second friction brake system including diverting a flow of brake cooling fluid to the systems based on the use of the systems.

1. A method of cooling a first friction brake system and a second friction brake system in a machine having a brake cooling system including fluid and a fluid diverter, the method comprising: determining whether the first friction brake system is activated;determining whether the second friction brake system is activated;circulating, with a first set of pumps including at least one pump, fluid through the brake cooling system to the first friction brake system and the second friction brake system;circulating, with a second set of pumps including at least one pump, fluid through at least one hydraulic system;combining the flow of fluid from the first set of pumps and the flow of fluid from the second set of pumps; anddiverting fluid between the first friction brake system and the second friction brake system based on a first brake enable switch for the activation of the first friction brake system and based on a second brake enable switch for the activation of the second friction brake system. 2. The method of claim 1 further comprising the step of delaying the diversion of the fluid until the fluid reaches a predetermined temperature. 3. The method of claim 1 wherein the step of determining whether the first friction brake system is activated includes monitoring a manual retarder torque setting and an automatic retarder torque setting. 4. The method of claim 1 wherein the step of determining whether the second friction brake system is activated further includes monitoring a manual retarder torque setting and an automatic retarder torque setting. 5. The method of claim 1 further including the step of diverting 40% of the fluid to the first friction brake system when both the first friction brake system and the second friction brake system are activated. 6. The method of claim 1 further including the step of diverting 90% of the fluid to the first friction brake system when the first friction brake system is activated and the second friction brake system is not activated. 7. A friction brake cooling system comprising: at least one first pump in a first set of pumps connected to at least one reservoir containing fluid and configured to provide a fluid flow to at least one valve in fluid communication with the first pump;at least one second pump in a second set of pumps connected to the reservoir and configured to provide fluid to at least one hydraulic system and configured to provide fluid flow to the valve in fluid communication with the first pump and the second pump;a first friction brake system in fluid communication with the valve and a second friction brake system in fluid communication with the valve such that cooling fluid from the reservoir is pumped through the valve to the first friction brake system and to the second friction brake system;at least one controller configured to divert the cooling fluid flow through the valve to the first friction brake system and to the second friction brake system based, on a first brake enable switch for the activation of the first friction brake system and a second brake enable switch for the activation of the second friction brake system. 8. The friction brake cooling system of claim 7 wherein the first pump is dedicated to the friction brake cooling system. 9. The friction brake cooling system of claim 8 wherein a flow of the fluid from at least one third pump is directed to the valve. 10. The friction brake cooling system of claim 9 wherein the fluid is separate from hydraulic fluid used for at least one hydraulic system associated with the machine. 11. The friction brake cooling system of claim 7 wherein the fluid is hydraulic fluid used for at least one hydraulic system associated with the machine. 12. The friction brake cooling system of claim 7 wherein the valve diverts 90% of the flow to the first friction brake system when the second friction brake system is not activated and is configured to divert 40% of the flow to the first friction brake system when the second friction brake system is activated.
