Locate the emergency brake adjustment nut. It is located under the vehicle, near the rear wheels.
Raise the vehicle using a jack or ramps.
Chock the wheels that are on the ground.
Locate the cable adjuster on the emergency brake lever. It is located near the base of the lever.
Turn the cable adjuster clockwise until you can feel resistance.
Lower the vehicle and test the emergency brake. It should now engage and hold the vehicle securely.
Here are some additional tips for adjusting emergency brakes:
Make sure that the emergency brake is disengaged before you adjust it.
If the emergency brake is engaged, it will be difficult to turn the cable adjuster.
The emergency brake should be adjusted so that it engages and holds the vehicle securely when the lever is pulled all the way up.
If the emergency brake is not engaging or holding the vehicle securely, it may need to be repaired.
It's important to consult your vehicle's owner's manual or a qualified mechanic for specific instructions on adjusting the emergency brakes on your GMC Envoy.
