Chevrolet Silverado: Brakes / Electric Brake Boost

Chevrolet Silverado 2019-2025 Owners Manual / Driving and Operating / Brakes / Electric Brake Boost

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.
