Chevrolet Silverado: Brakes / Electric Parking Brake

The vehicle has an Electric Parking Brake (EPB). The EPB can always be activated, even if the ignition is off. To prevent draining the battery, avoid repeated cycles of the EPB when the engine is not running.

The system has a or PARK Electric Parking Brake light, and a Service Parking Brake light. See Electric Parking Brake Light and Service Electric Parking Brake Light.  There are also parking brake-related Driver Information Center (DIC) messages.

Before leaving the vehicle, check for the or PARK light to ensure that the parking brake is applied.

EPB Apply

To apply the EPB:

1. Be sure the vehicle is at a complete stop.

2. Press the EPB switch momentarily.

The or PARK light will flash and then stay on once the EPB is fully applied. If the or PARK light flashes continuously, then the EPB is only partially applied or there is a problem with the EPB. A DIC message will display. Release the EPB and try to apply it again. If the light does not come on, or keeps flashing, have the vehicle serviced. Do not drive the vehicle if the or PARK light is flashing. See your dealer. See Electric Parking Brake Light.

If the light is on, press the EPB switch and hold it. Continue to hold the switch until the or PARK light remains on. If the light remains on, see your dealer.

If the EPB is applied while the vehicle is moving, the vehicle will decelerate as long as the switch is pressed. If the switch is pressed until the vehicle comes to a stop, the EPB will remain applied.

The vehicle may automatically apply the EPB in some situations when the vehicle is not moving. This is normal, and is done to periodically check the correct operation of the EPB system.

If the EPB fails to apply, block the rear wheels to prevent vehicle movement.

EPB Release

To release the EPB:

1. Turn the ignition on or to ACC/ACCESSORY.
2. Apply and hold the brake pedal.
3. Press the EPB switch momentarily.

The EPB is released when the or PARK light is off.

If the light is on, release the EPB by pressing and holding the EPB switch. Continue to hold the switch until the or PARK light is off. If either light stays on after release is attempted, see your dealer.

Caution

Driving with the parking brake on can overheat the brake system and cause premature wear or damage to brake system parts. Make sure that the parking brake is fully released and the brake warning light is off before driving.

Automatic EPB Release

The EPB will automatically release if the vehicle is running, placed into gear, and an attempt is made to drive away. Avoid rapid acceleration when the EPB is applied, to preserve parking brake lining life.
