Chevrolet Silverado: Brakes / Electric Brake Boost
Vehicles equipped with electric brake boost have hydraulic brake circuits that
are electronically controlled when the brake pedal is applied during normal operation.
The system performs routine tests and turns off within a few minutes after the vehicle
is shutdown. Noise may be heard during this time. If the brake pedal is pressed
during the tests or when the electric brake boost system is off, a noticeable change
in pedal force and travel may be felt. This is normal.
The Antilock Brake System (ABS) helps prevent a braking skid and maintain steering
while braking hard.
ABS performs a system check when the vehicle is first driven...
Other information:
Premium unleaded gasoline meeting ASTM specification D4814 with a posted octane
rating of 93 — (R+M)/2 — is highly recommended for best performance and fuel economy.
Unleaded gasoline with an octane rated as low as 87 can be used. Using unleaded
gasoline rated below 93 octane, however, will lead to reduced acceleration and fuel
economy...
If this vehicle came with a full-size spare tire, it was fully inflated when
new, however, it can lose air over time. Check the inflation pressure regularly.
See Tire Pressure and Vehicle Load Limits. For instructions on how to remove, install,
