Brake response time test system

Overview

The system also supports tractor and trailer EBS response time tests.

Brake response time test system equipment is used to test the vehicle pneumatic brake system, including the brake response time test of the tractor, the failure of the tractor simulation control pipeline, the sealing test of the motor vehicle brake pipeline, and the trailer brake response time test , Trailer brake release time test. Strictly follow national standards, synchronous data sampling and automatic data processing.

●Test items

Towing vehicle braking response time test
