UNIT.

BRAKE UNIT
Hardened steel cams are used for operating and expanding the shoes against the brake drums. Adjustment
may be accomplished on the linkage provided at the cam control lever without disturbing the original cable
setting. All steel parts are cadmium plated.

All assemblies are interchangeable, left and right.

WHEELS
Wheels are die castings of high strength aluminum alloy designed for maximum strength and durability.
These wheels come in halves clamped together with alloy steel cadmium plated bolts.

Flanges are knurled to secure, firm grip on the tire casings. The brake drum is heavy gauge pressed steel
with an approximate total braking area of 25.5 square inches per wheel.

GOODYEAR SINGLE DISC TYPE MECHANICAL BRAKE, ASSEMBLY #95-2213, WHEEL #95-2311.

PRINCIPLES OF OPERATION
Friction is applied to the chromium plated steel brake disc by flat segments of molded brake lining secured
in the inner and outer aluminum cast housing. The outer housing incorporates a lever and pin arrangement,
spring loaded, which when actuated by pressure on the brake pedal presses the lining discs against the
floating rotating wheel disc.

ADJUSTMENT
1. Back off adjusting screw lock nut.
2. Turn adjusting screw until snug and perceptible drag is noted when wheel is turned by hand.
3. Back off adjusting screw one quarter turn.
4. Hold adjusting screw with screwdriver and tighten lock nut.

SERVICE, INSPECTION, MAINTENANCE AND LUBRICATION

Working parts of the brake must be kept free of dirt and foreign matter, and be able to work freely.

Replacement of linings should be made if they are worn to less than 0.160 of an inch thickness.

To disassemble braking mechanism, it is necessary to remove wheel from axle and remove bolts from the
disc retainer housings. All assemblies are interchangeable left and right.
