DESCRIPTION
DESCRIPTION - ANTILOCK BRAKES
This section covers the physical and operational
descriptions and the on-car service procedures for
vehicles equipped with the Mark 20e Antilock Brake
System and the Mark 20e Antilock Brake System
with traction control.
The purpose of this four-channel design antilock
brake system is to prevent wheel lockup under brak-
ing conditions on virtually any type of road surface.
Antilock braking is desirable because a vehicle that
is stopped without locking the wheels retains direc-
tional stability and some steering capability. This
