1. The MICO 691 System is a supplemental safety
device which provides additional brake holding
action when used with existing vehicle parking
brake. It is not for dynamic service braking.

an audible and/or visual alarm as a warning to
signal the user of any loss of brake system pres-
sure. Do not disconnect warning devices.
3. All lines, fittings and surrounding areas must be
cleaned of dirt or road residue before any lines or
fittings are disconnected. Special care must be
taken so dirt and road residue are not allowed to
enter the hydraulic brake system. This can con-
taminate the system and interfere with proper
operation of brakes and MICO 691 System.
4. Follow procedures outlined in Vehicle Manufac-
turer's Service Manual or SAE Standards when
making new connections or adding to existing
