DESCRIPTION

The Bendix Piggyback Spring Brake is made up of a

conventional brake chamber and an emergency or parking

spring mechanism for use on vehicles equipped with cam

foundation brakes. The Spring Brake Actuator provides: (1)

Service Braking, (2) Parking and (3) Emergency Braking.

The actuator can be piped with various system arrangements

to be automatically or manually applied under emergency

braking conditions.

The spring brake is a diaphragm type actuator which converts

the energy of air pressure into mechanical force. The

diaphragm is held between the pressure plate and non-

pressure plate by a two piece clamp ring.

Different size brake chambers are identified by numbers

which specify the effective area of a diaphragm. For example,

a Type 30/30 Spring Brake has 30 square inches of effective

area on each diaphragm.

The standard diaphragm material is a compound of natural

rubber with a fabric interior of nylon.

PREVENTIVE MAINTENANCE

Important: Review the warranty policy before performing

any intrusive maintenance procedures. An extended warranty

may be voided if intrusive maintenance is performed during

this period.

Because no two vehicles operate under identical conditions,

maintenance intervals will vary. Experience is a valuable guide

in determining the best maintenance interval for a vehicle.

WARNING!

Piggyback Spring Brake Chambers contain a loaded

compression spring. Property damage, serious injury

or death may occur if instructions are not followed

completely.

Every 300 operating hours, 8,000 miles, or one (1) month:

1. Check push rod travel and adjust travel at the slack

adjuster if needed. Push rod travel should be as short

as possible without the brakes dragging. Excessive push

rod travel reduces braking efficiency, shortens diaphragm

life, gives slow braking response and wastes air.
