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
