TM 9-2350-273-BD CHAPTER 8 BRAKES BDAR FIXES SHALL BE USED ONLY IN COMBAT AT THE DISCRETION OF THE COMMANDER AND SHALL BE REPAIRED BY STANDARD MAINTENANCE PROCEDURES AS SOON AS PRACTICABLE AFTER THE MISSION IS COMPLETED. SECTION I. General 8-1. General. The vehicle service brake is a hydromechanical system. A master cylinder and two slave cylinders are used to apply the brake bands-inside the transmission and stop the tank. The steering system uses braking action to steer the tank by applying braking action to one side or the other. This allows the steering to be used to stop the tank should the hydraulic brake system fail. The parking brake has mechanical linkage to the transmission which locks the transmission in a braked condition. 8-2. Assessment Procedure a. Assessment Preconditions: Before testing the vehicle brakes, clear the immediate area or, if in a restricted area, restrain the vehicle to be tested with chains or cables.
