The brake cooling pump is run off the transmission and constantly circulates oil though the two front brake housings. The oil flows out of pump (2) and into the front brake housings through hose (1). The oil then flows from the brake housing (4) to transmission. The cooling oil is part of the transmission oil system and will be cooled by the transmission oil cooler. The brake cooling oil is filtered through the transmission oil filter (9). Refer to Illustration.3 for a picture.Oil Filter (Brake Cooling Oil)
