Wet brake oil provides cooling and should exhibit good friction properties. A hydraulic/transmission fluid with ideal friction characteristics combines good stopping power or capacity with smooth engagements and minimal noise or chatter.
The fluid also must be matched with ambient temperature. Consideration must be given to
oxidation, contamination, compatibility, and other properties. Use of multiple friction material
such as sintered bronze, paper, and composites makes formulation of single oil for all use
difficult.
Wet multi-disc brakes run in oil, which dissipates the considerable heat generated and keeps the brakes working efficiently. Two types of cooling systems are used. A “sump” cooling system uses non-circulating oil, which can be a special oil sealed in the brake housing, or simply oil that is shared with the differential or final drives.
