Troubleshoot: Curt RVi 4 Braking System Chirped Tires First Time Using It
Updated 09/03/2025 | Published 08/07/2025
Question:
I installed the Curt RVi4 and the tires chirped the first few times I braked. Normal?

Expert Reply:
That’s actually a common and temporary side effect, Greg. Most towed vehicles store a little vacuum brake assist even after the engine shuts off. During setup, the Curt Braking System # RVi44FR removes that vacuum assist to prevent overbraking, but if the engine runs during or after setup, it reintroduces it. Just unplug the unit while the vehicle is running, then repeat the Auto Position process to clear it before towing. See attached photo.
You may also need to adjust sensitivity. Let me know if you need more help after trying these.

Got it, Andrew. So once I reset it, that chirping should go away for good?
