<strong>Cadillac</strong><br />
without locking when the car is in any drive<br />
range with the engine running.<br />
C. The power brake vacuum booster assures dependable<br />
high speed and high altitude braking<br />
performance.<br />
D. Corrosion-resistant brake lines and rayon cord<br />
brake hoses assure increased durability and long<br />
life.<br />
E. Wheel cylinder pistons are super-hard and selflubricating<br />
for maximum reliability and long life.<br />
F. Front disc brakes have a ventilated rotor with<br />
center openings that allow air to flow past the<br />
braking surface for extremely rapid cooling. A<br />
shield protects the inboard disc and lining<br />
against road splash. The wheel envelopes the<br />
iple Braking System (continued)<br />
outboard disc and lining to complete the<br />
shielding.<br />
G. The two rear brake drums are finned for fast heat<br />
dissipation. A flange on the rear brake backing<br />
plate shields interior of drums from water. Rear<br />
brakes adjust automatically when the car is in<br />
reverse and the brakes applied.<br />
H. Front disc brakes adjust themselves automatically<br />
during brake application. Correct shoe/<br />
rotor clearance is provided by a piston sliding on<br />
a piston seal during braking, placing the seal<br />
under tension. The piston gradually changes<br />
position relative to the seal as the brake lining<br />
wears, thereby maintaining proper shoe/rotor<br />
clearance.<br />
Shock Absorbers<br />

Another feature that contributes to <strong>Cadillac</strong>'s luxurious<br />
ride and outstanding handling is the exclusive<br />
shock absorber, with a gas-filled nylon envelope to<br />
prevent air from mixing with the fluid. Both front<br />
and rear shock absorbers are specially calibrated to<br />
precision level the car with the slightest movement<br />
and make shock absorption smooth and easy. They<br />
are also designed to give uniform action in a variety<br />
of climates.<br />
Front Suspension<br />
<strong>Cadillac</strong>'s independent spring-type front suspension,<br />
which accounts for its famed ride and handling,<br />
has been improved for <strong>1969</strong>. The helical-coil springs<br />
have been adjusted for better load characteristics,<br />
giving neither too firm a ride nor too soft a ride. New<br />
upper control arm rubber bushings increase the<br />
cushioning of road noise. Strut rods are mounted<br />
to the lower control arms and, through rubber bushings,<br />
to the frame crossmember for proper wheel<br />
alignment. Yet they do permit a momentary rearward<br />
deflection of the wheel when it encounters a road<br />
bump for a softer ride.<br />
