Question
How to test electronic parking brake (EPB) actuator functionality after brake pad replacement?
Answer
Perform "actuator stroke test" and verify force feedback via diagnostic tool.
Explain
EPB actuators need calibration after pad replacement to avoid uneven braking. CHEPQ tools command the actuator to extend/retract fully (stroke test) and measure force (optimal: 800-1200N for passenger cars), ensuring the actuator applies consistent pressure—preventing brake drag or weak parking hold.
