2022 Chevrolet Silverado 1500 Brakes
Brakes
Electric Brake Boost
- Vehicles equipped with electric brake boosts have hydraulic brake circuits that are electronically controlled when the brake pedal is applied during normal operation.
- The system performs routine tests and turns them off within a few minutes after the vehicle is turned off. 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.
Antilock Brake System (ABS)
- The Antilock Brake System (ABS) helps prevent a braking skid and maintains steering while braking hard.
- ABS performs a system check when the vehicle is first driven. A momentary motor or clicking noise may be heard while this test is going on, and the brake pedal may move slightly. This is normal.
- If there is a problem with ABS, this warning light stays on. See Antilock Brake System (ABS) Warning Light 117.
- ABS does not change the time needed to get a foot on the brake pedal and does not always decrease stopping distance. If you get too close to the vehicle ahead, there will not be enough time to apply the brakes if that vehicle suddenly slows or stops. Always leave enough room ahead to stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold the brake pedal down firmly. Hearing or feeling ABS operate is normal.
Braking in Emergencies
ABS allows steering and braking at the same time. In many emergencies, steering can help even more than braking.
Electric Parking Brake
- The Electric Parking Brake (EPB) can always be applied, even if the vehicle is off. In case of insufficient electrical power, the EPB cannot be applied or released. To prevent draining the battery, avoid unnecessary repeated cycles of the EPB.
- The system has a red parking brake status light and an amber service parking brake warning light. See Electric Parking Brake Light 116 and Service Electric Parking Brake Light 116.
- There are also parking brake-related Driver Information Center (DIC) messages.
- Before leaving the vehicle, check the red parking brake status light to ensure that the parking brake is applied.
EPB Apply
To apply the EPB:
- Be sure the vehicle is at a complete stop.
- Press the EPB switch momentarily.
The red parking brake status light will flash and then stay on once the EPB is fully applied. If the red parking brake status 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 red parking brake status light is flashing. See your dealer. If the amber service parking brake warninglight is on, press the EPB switch. Continue to hold the switch until the red parking brake status light remains on. If the amber service parking brake warning light is 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, or at the request of other safety functions that utilize the EPB. If the EPB fails to apply, block the rear wheels to prevent vehicle movement.
EPB Release
To release the EPB:
- Turn the ignition on or to ACC/ACCESSORY.
- Apply and hold the brake pedal.
- Press the EPB switch momentarily.
- The EPB is released when the red parking brake status light is off.
- If the amber service parking brake warning light is on, release the EPB by pressing and holding the EPB switch. Continue to hold the switch until the red parking brake status 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.
If you are towing a trailer and parking on a hill, see Driving Characteristics and Towing Tips 0 305.
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.
Brake Assist
Brake Assist detects rapid brake pedal applications due to emergency braking situations and provides additional braking to activate the Antilock Brake System (ABS) if the brake pedal is not pushed hard enough to activate ABS normally. Minor noise, brake pedal pulsation, and/or pedal movement during this time may occur. Continue to apply the brake pedal as the driving situation dictates. Brake Assist disengages when the brake pedal is released.
Hill Start Assist (HSA)
Warning
Do not rely on the HSA feature. HSA does not replace the need to pay attention and drive safely. You may not hear or feel alerts or warnings provided by this system. Failure to use proper care when driving may result in injury, death, or vehicle damage. See Defensive Driving 201.
- When the vehicle is stopped on a grade, Hill Start Assist (HSA) prevents the vehicle from rolling in an unintended direction during the transition from brake pedal release to accelerator pedal apply.
- The brakes release when the accelerator pedal is applied.
- If the accelerator pedal is not applied within a few minutes, the Electric Parking Brake will apply. The brakes may also release under other conditions. Do not rely on HSA to hold the vehicle.
- HSA is available when the vehicle is facing uphill in a forward gear, or when facing downhill in R (Reverse). The vehicle must come to a complete stop on a grade for HSA to activate.
