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.
Anti-lock brake system (ABS) (if equipped)
On vehicles 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. The ABS performs a self-check at 17 km/h (10
mph) after you start the engine and begin to drive away. A brief
mechanical noise may be heard during this test. This is normal. If a
malfunction is found, the ABS warning light will come on. 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 compensating 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.
