The 2021 GMC Sierra Service ESC (Electronic Stability Control) is a system that helps to keep your vehicle stable and in control. It works by applying brakes to each wheel individually and adjusting the engine throttle to help keep you in your lane.

It is important to note that ESC is not a substitute for safe driving practices, but rather an additional layer of protection for your vehicle.

Benefits of ESC

The primary benefit of having an Electronic Stability Control system in your 2021 GMC Sierra is improved safety and control. The system helps to keep you from losing control of your vehicle in slippery road conditions or when cornering at high speeds. In some cases, it can even help reduce the risk of a rollover crash. Additionally, having the ESC system turned on can also improve fuel efficiency by reducing wheel spin and improving traction.

Parking Brake Details

The parking brake on the 2021 GMC Sierra is designed to help keep your vehicle stationary when parked on an incline or decline or when stopped in traffic. It operates by using a lever located inside the car that applies pressure against the rear wheels to prevent them from moving while parked. The lever should be engaged when parking on an incline or decline and should be disengaged prior to driving away again.

Working Mechanism

The parking brake lever connects directly to two cables that run along either side of the car’s frame and are connected at each wheel by a small wheel cylinder. When engaged, these cables pull against the wheel cylinders which then apply pressure against each wheel’s brake shoes which prevents them from turning when parked.

Benefits of Parking Brake

Having a properly working parking brake provides several benefits for your 2021 GMC Sierra. Primarily, it helps ensure that your vehicle stays stationary on an incline or decline even if it has been left unattended for long periods of time as well as during traffic stops where you cannot depend solely on traditional brakes alone due to their lack of strength.
