We only had our Bus for a few hours when my dog knocked into the airbrake. Thankfully, we were level, and I was chalked. This solves that issue entirely and looks cool to boot! Installing it was super easy. They even had a link on the box to show you how to do it.

A great addition for our Super C motorhome. we have a large black lab that goes wild when we leave him unattended in the RV. This invention really releaves us of the air brake ever getting released by him. Great Idea!

I recently installed this Parking Brake Safety Lock to replace the yellow air brake knob in my Class A motorhome, and it's been a great safety upgrade. I love knowing that this lock prevents an accidental parking brake release, especially with pets and kids around. It’s reassuring to have an extra layer of protection when my motorhome is parked—no worries about someone or something accidentally disengaging the brake.The installed ‘Stop Knob’ looks great, and they even included a special tool to remove the old brake handle and accomplish the installation. The design is awesome and easy to use; the locking mechanism simply screws down to prevent the knob from being released. I can now clean the control panel area around the parking brake without any concern about it being disengaged accidentally. Additionally, the customer service team is top-notch; I had a question about installation, and they responded to my inquiry the same day and scheduled a phone consultation to assist with my question. They provided follow-up communications to ensure I didn’t encounter any issues which made me feel extremely satisfied with this product. I highly recommend the ‘Stop Knob’ upgrade for added peace of mind for ensuring your RV parking brake is secure!

Nice touch on our motorhome and enhances the safety of the unit when parked.

We Park our Tiffin Super C in our driveway after trips until we prepare it for storage. 2 years ago my wife was cleaning our RV and accidently released the air brake. The RV rolled about 15 feet into our garage damaging our house and RV. It could of been worse. Eversince then, I have been putting a clothing clip while parked. I'm so glad I found this simple solution. It was fast to install and actually looks really nice on the dash. Nice safety addition.

I have never accidentally pushed in my air brakes but do see the potential.This was an easy swap with my thin flat button (rolled pin install)They supplied the tool to extract the roll pin, it took a little time but was easy enough.The new knob has 2 interlocking screws that secure it in place, they supply the 2 tiny screw drivers to help with installation.One the airbrake in on, spin the lock down to hold it securely “On”. The threaded lock ring also covers the screws so they will not back out.Cost at time of review $99.00Overall, a simple solution for a potential problem. It is a bit pricey, but easy to use.

Great Product. We travel with dogs, we don�t leave them a lot but when getting fuel, checking into campgrounds, grabbing a quick bite, they always go to the dash and watch us walk away. Now no worries about the parking brake getting released by one of them.
