Abstract
A heavy vehicle, such as a tractor scraper, has oil cooled front disc brakes, and oil cooled rear disc brakes that may be used alone or in conjunction with the front brakes. A rear brake cooling circuit and a front brake cooling circuit, each of which has its own pump and heat exchanger, are cross-connected through a common reservoir, and both pumps and heat exchangers function whenever the rear brakes are applied. The rear circuit heat exchanger is an oil cooler with a fan, the motor for which is driven from the pump output and discharges to the cooler; and the motor may drive a bypass pump which draws some oil from the return line and passes it through the cooler.
