Comment. The slope of the road is 23%, this is when the car will go down a little more than one meter for a 5 m path.
Execution sequence
1. We stop the car on a steep slope of at least 23% of the asphalt road and, pressing the brake pedal, hold it with the service brake.
2. Raise the parking brake lever all the way, counting the number of clicks.
3. Having released the pedal, we make sure that the parking brake is working.
Recommendation. If the car is not held by the parking brake on a slope, or during the test you counted seven or more clicks of the locking mechanism, you need to check the condition of the parking brake pads and drum and adjust the parking brake (see «Parking brake - adjustment»).
