Question:
I have a 2025 Chevy Trailblazer LT. I know I will have to play around to get it exact but what brake sensitivity should I start off with on the brake buddy 3?

Hey Carrie, there is no set sensitivity setting for the Brake Buddy Select 3 Portable Flat Tow Brake System # HM39524 and your 2025 Chevy Trailblazer.
What you're going to need to do is set the braking power for 25 - 45 psi and go from there. The setting should be enough that your towed vehicle still gives a slight tug at your RV when you brake. If you find that you need more or less PSI you can just adjust from there.

Hey Carrie, how did things go after setting your Brake Buddy Select 3 around that 25–45 psi range on your Trailblazer? Did you find a sweet spot where the braking felt smooth and balanced? Your update could make it easier for others dialing in the same setup.
