Product Details

The Demco Duo Supplemental Braking System (Model 9599006) is an inertia-based braking solution designed for flat-towed vehicles behind motorhomes. This compact system provides reliable, proportional braking that activates automatically when the motorhome slows down, ensuring safer stops and reduced wear on your RV's brakes.

Key Features:

  • Inertia-activated design responds proportionally to motorhome braking force
  • Industry-leading compact actuator installs discreetly under the hood
  • Air-powered operation delivers quick, consistent brake application
  • Simple one-time installation with minimal visible components
  • No dash-mounted controls or visible equipment in towed vehicle cabin
  • Compatible with most vehicles equipped with power brakes
  • Breakaway protection for added safety

The Duo system eliminates the need for complex electronics or driver intervention. Once installed, it works automatically every time you tow, applying the towed vehicle's brakes in proportion to your motorhome's deceleration. The under-hood installation keeps your towed vehicle's interior uncluttered while providing reliable supplemental braking performance for a safer, more controlled towing experience.

The woman on the phone was able to give me shipping dates which were very helpful.

Great price and very easy...

Great price!

Very easy!!!

Very easy to find and purchase what I needed. It showed up at a reasonable time.

Had to reorder due to wrong part sent. When I called to return the product I was hung up on twice. Returning the part has been a hassle. Its been a week and still not returned yet. Plus they needed a pic to return it. Never had to do that before.
