Electrohydraulic
691 Brake Lock System

(supplemental brake holding device)
DESCRIPTION

MICO® Brake Lock Systems lock hydraulic pressure
in the service brakes to supplement the vehicle’s
mechanical parking brake and provide extra holding
in heavy-duty and high-frequency applications. The
691 consists of a small electrohydraulic pump, remote
mounted actuator (single and/or dual), electronic control
module and small dash-mounted user interface. The
operator simply activates a switch and the 691 system
automatically applies, monitors, and maintains brake
locking pressure.
The 691 Brake Lock significantly enhances vehicleholding capability while not interfering with normal
service brake function and provides added safety for
operator, vehicle, and work area.

FEATURES

● Supplements existing parking brake for additional
holding
● Automatically monitors and maintains optimal brake
lock system pressure
● Activates with the flip of a switch
● Can be remotely controlled
● Can be interlocked with other 12-volt systems
● Microprocessor controlled with onboard diagnostic
LED’s
● Waterproof control module
● Factory provided weatherproof connectors
● Wide selection of models

In addition to operator control via the “Lock/Release”
switch on the user interface, 691 systems can be
remotely controlled and/or interlocked using leads in
the main wiring harness. This allows control of the
brake lock system from locations outside the cab. As
an interlock, 691 operation is linked to other vehicle
systems and components; for example, wheelchair
lift, PTO, electrical generator, hydraulic pump, air
compressor, etc. to ensure that whenever they are
being used the brakes are locked and the vehicle is
immobilized.
