BRAKES
SECTION II. Brake BDAR
8-4. General.
The service brakes are actuated by a master cylinder and two slave cylinders. Cylinder
leakage and internal corrosion are the most common modes of failure. Several methods
are available to regain the use of the brakes if repair parts are not available.
8-5. BRAKE MASTER CYLINDER FAILURE
General Information
Master cylinder failure will degrade the stopping capability of the tank. The master
cylinder should be replaced with a new or substitute item. A 5-ton truck master
cylinder is physically the same on the outside. The internal fluid return ports are
different but the bore diameter is the same. The piston cups are the same as those on
M48/M60.
