Disc Brakes
Power assisted front disc brakes, featuring a single
piston and floating caliper, are standard on all
models and add a new dimension to positive braking
action. This is especially important in today's high
mileage motoring, whether it be on high-speed
turnpikes or in brake-punishing mountainous terrain.
Attributes of this system include consistent straight
line braking, lack of brake fade, exceptionally durable
brake lining and virtually full shielding from dust
and road splash. Basically, the system works like
this: A ventilated rotor attaches to the wheel hub
and rotates with the wheel. A caliper assembly,
which straddles the rotor, contains two directly
opposed shoe and lining assemblies and a single
piston. The caliper assembly also contains two guide
pins which permit the caliper to move or "float"
laterally. On brake application, equal movement of
the piston and floating caliper forces the two opposing
shoe and lining assemblies to exert equal
pressure to both faces of the revolving rotor in
vise-like fashion. This design provides automatic
adjustment of clearance between the rotor and brake
lining following each application. A slightly larger
diameter rotor is used on the Eldorado because of
it's front wheel drive design.

Three-Speed Windshield Ws
Windshield wipers on all models ar& recessed out of
sight at the base of the windshield when not in
use to enhance the Cadillac's overall smooth, sleek
styling. The new tandem, left-hand articulated system
gives a wipe pattern that provides better wetweather
visibility. With this system, the wiper blades
travel in the same direction at the same time with
the left-hand or driver's side blade moving into a
position parallel to the windshield pillar. Glarereducing
windshield wiper arms give minimum reflection.
Windshield wipers have a 3-speed control
for low, medium and high operation. The control
unit is now located on the door panel in an upward
canted position for easier accessibility. When activated,
the washer automatically delivers twin sprays
of washer solution to each side of the windshield
before the wiper blades begin their low-speed
wiping action.
