Beschreibung
Zusammenfassung:	A braking system 200 for a machine, for example a wheel loader or a tractor, includes an accumulator 210 for storing oil under pressure, at least one brake pack 212 in selective fluid communication with accumulator 210 and a hydraulic tank 214 in selective fluid communication with brake pack 212. A brake valve 208 allows oil to flow from accumulator 210 towards brake pack 212 in an opened state and from brake pack 212 towards hydraulic tank 214 in a closed state. A control module 206 is communicably coupled with brake valve 208, and transmits control signals to brake valve 208 for opening and closing the valve at least once to reduce oil pressure in accumulator 210 below a predetermined threshold. The system may allow accumulator 210 to be efficiently drained, for example during or after shutdown of the machine.
