3 Overview

The parking test device measures the braking force of the motor vehicle in the parking brake state on a flat road surface, and can be integrated Instrument or measuring device for evaluating the performance of parking brakes. Traction parking test device detects the station of the vehicle at the time of parking The vehicle braking force and the skateboard parking test device detect the parking brake force of each wheel (shaft). The traction type parking test device is mainly composed of a traction device, a force sensor and a meter. Skateboard parking test equipment The main components are composed of traction slides, force sensors and meters.

4 Measurement characteristics
