The White Drive Products Release pump (RP) is a device designed to replace existing costly and complicated hydraulic brake release hand pumps that are present on various types of mobile equipment. The RP is typically used to release various types of spring applied/hydraulically released brakes. Depending on the brake typically 1-5 pumps of the RP will release the brake. This enables equipment to be moved to a service area or a recharge/refuel station.Pictures shown are for illustration purposes. Prices subject to change without notice.
