New to the 2014 Sierra, four-wheel-disc brakes are now standard on all cab configurations. These new brake discs undergo a GM-exclusive process in which the brake surfaces are hardened and strengthened to reduce corrosion and extend brake life…up to double the life of conventional rotors. Sierra owners will now experience quieter braking with less vibration.
Another method of providing Sierra owners with better fuel economy is the elimination of the engine-driven hydraulic power steering pump. Replacing this older technology is a new electric motor, which results in more consistent steering feel no matter the engine or vehicle speed. Parking should be even easier now with the 2014 Sierra.
