BRAKES

Your service brakes are self-adjusting. Refer to the scheduled

maintenance guide for scheduled maintenance.

Occasional brake noise is normal and often does not indicate a

performance concern with the vehicle’s brake system. In normal

operation, automotive brake systems may emit occasional or intermittent

squeal or groan noises when the brakes are applied. Such noises are

usually heard during the first few brake applications in the morning;

however, they may be heard at any time while braking and can be

aggravated by environmental conditions such as cold, heat, moisture,

road dust, salt or mud. If a “metal-to-metal,” “continuous grinding” or

“continuous squeal” sound is present while braking, the brake linings

may be worn-out and should be inspected by a qualified service

technician.

Four-wheel anti-lock brake system (ABS)

This vehicle is equipped with an anti-lock braking system (ABS). A noise

from the hydraulic pump motor and pulsation in the pedal may be

observed during ABS braking events. Pedal pulsation coupled with noise

while braking under panic conditions or on loose gravel, bumps, wet or

snowy roads is normal and indicates proper functioning of the vehicle’s

anti-lock brake system. If the vehicle has continuous vibration or shudder

in the steering wheel while braking, the vehicle should be inspected by a

qualified service technician.

The ABS operates by detecting the

onset of wheel lockup during brake

applications and compensates for

this tendency. The wheels are

prevented from locking even when

the brakes are firmly applied. The

accompanying illustration depicts

the advantage of an ABS equipped

vehicle (on bottom) to a non-ABS

equipped vehicle (on top) during hard braking with loss of front braking

traction.
