How to Keep My Boat Trailer Surge Brakes From Locking Up
Updated 07/30/2021 | Published 07/24/2021
Question:
I have a 2013 GMC Sierra 2500HD Duramax. When I put my truck in reverse to launch my boat or put it on the trailer the brakes will some times lock up. I know they’re surge brakes but don’t know how to fix it. My boat is a 2019 Malibu 24MXZ.

Expert Reply:
With surge brakes, you have a brake actuator applying the needed pressure to the brakes. In order to back up you will need to have a manual lockout or an electric lockout solenoid, like the Replacement Solenoid Valve # T4748800, which will close when you shift the vehicle into reverse, allowing the trailer to be backed up.
