DESCRIPTION
The Bendix
MC-11
tractor antilock assembly is designed
®
™
to improve vehicle stability by reducing wheel lock-up during
aggressive braking. Like the MC-10
it replaces, the MC-11
™
one-channel system–it uses one modulator. And the system
can control single or tandem axles. The antilock assembly
mounts to the vehicle frame and usually replaces the drive
axle service relay valve.
The MC-11
tractor antilock assembly consists of an EC-11
™
electronic controller and an M-12
controller houses the electronics that regulate the antilock
system. The electronics are protected by a self-healing
silicone compound. The EC-11
diagnostic window and reset switch, and its 14 pin connector
is the electrical link to the rest of the antilock system. (See
Figure 2.) The controller mounts to the modulator with four
cap screws, and it is electrically connected to the modulator
