DESCRIPTION
GENERAL
Bendix antilock systems utilizing the EC-15
™
electronic
controller assembly provide full vehicle, wheel control
braking for buses, trucks, and truck tractors. By minimizing
the potential of “brake lock-up” on all wheels during
aggressive braking the vehicle retains a high degree of
stability and steerability, and in most cases vehicle stopping
distance is reduced.
braking for buses, trucks, and truck tractors. By minimizing

In order to provide full vehicle, wheel control braking, the
EC-15
EC-15
™
controller assembly is used in combination with
the following components:
- Four, individual wheel speed sensors
- Four, air pressure modulator valves
- Antilock condition lamp (dash mounted)
PHYSICAL
The EC-15
™
controller electronics, that regulate the function
of the antilock system, are contained in a die cast aluminum
housing and are environmentally protected. The metal
housing, coupled with the design of the digital electronics,
is intended to provide a high degree of protection from
radio and electromagnetic interference.

A diagnostics display window with 9 light emitting diodes
(LEDs) and a magnetically actuated reset switch is
incorporated in the housing for troubleshooting and
diagnostic purposes.
