For some time all trucks have been equipped with a new design rear brake housing plate.
The new housing plate is provided with a protective shield that lessens any possibility of water or dirt getting into the brakes.
The new housing plate and brake shield assembly AA-2211-B can be installed on all trucks having the emergency brake in the center.
To install the new plate on an old housing, remove the rear wheels, brake shoes and emergency brake carrier plate. After removing these parts, the new housing plate and bracket assembly AA-2211-B can be installed (see Fig. 826).
AA-2212 shield is serviced only in the AA-2211-B assembly.
