Updated 09/05/2025 | Published 08/31/2025

Question:

With the Demco staynplay how can I lower the sensitivity so the tow vehicl brakes do not lock up. When installing the unit I was told the adjusting slide should be up to lower the intensity but right now I have it all the way up to stop the tow vehicle brakes from locking up.

Hello Martin, thanks for reaching out. The Demco Stay-IN-Play Duo Flat Tow Brake System # SM99251 allow you to adjust the sensitivity using the G-Force controller. It has a sider for adjusting the sensitivity so if you dial that back a bit it should prevent the brakes from locking up.

I would still like to know which way is least sensitive up or down. If you could tell me that then I will have a starting point to set up the brakes on the tow vehicle.

@MartinN Up would be less sensitive. Down is more sensitive.
