Subject: 
1970 FORD “L SERIES” MODEL DUAL AIR BRAKE 
 SYSTEM
The purpose of this bulletin is to generally familiarize you with the dual air brake system
standard on all 1970 “L Series” Ford Trucks.  Both four wheel and six wheel systems are
offered with either wedge or S Cam foundation brakes.  We have attached lithos of these
systems (SA 8042-63 used for six wheel, SA 8042-64 for four wheel) for your reference.
These systems provide a modulated emergency application of the Spring Brake
Actuators and a full spring application for parking.  In addition to normal service braking.
Three new Bendix Commercial Vehicle Systems LLC devices are used in these
systems:
1.  E-7 Dual Brake Valve
2.  R-7 Modulating Valve
3.  VM-1 Control Valve Manifold
