Invisibrake - for use with Towmaster2 Tow-Car-A-Frame

Invisibrake is an electronic vacuum servo assisted braking system that meets all the current (UNECE regulation 13) braking directive requirements for a Tow-Car A-Frame System. Providing safe and reliable braking for your tow car when it’s being towed.

Why use power brakes?

A lot of emphasis is put on braking systems for A-frames by people using them, by European legislators, and by the installers themselves. Rightly so, since most towcars weigh around 1000kg. The extra load inevitably means that your stopping distance is going to be increased (surveys suggest as much as 58% greater without assisted braking at 50mph).
Your towing vehicle’s brakes are designed to stop its weight, within a given legislated performance parameter that is deemed safe.

Our Roadmaster Invisibrake progressive power braking system will slow the towcar from behind the motorhome whenever it is needed. This means there is little or no force on the towbar or A-frame, no violent jerking of the components or destabilising of the tow vehicle. Overall, it dramatically reduces your braking distance (surveys suggest just 4% greater at 50mph).

Invisibrake meets all European trailer braking legislation. It is compact and can be hidden out of sight. The progressive braking means when you apply continuous braking force, so does the Invisibrake – the longer you brake in the motorhome, the harder your towed vehicle will brake (it will not skid your towcar tyres).

Other features

  • There is nothing to set up, adjust or even turn on. Just hook up and go.
  • The motorhome has an LED mounted as a visual reference when the system is braking.
  • The motorhome has an audible alarm if something goes wrong, and the brakes stay on in the towcar.
  • A breakaway cable activates the Invisibrake and brings the towcar to a stop if it detaches from the motorhome.
  • The braking pressure on the towcar’s pedal can be adjusted to suit if needed (normally set up during installation).
  • No controls for the system in the motorhome other than braking, so you can’t go wrong. This is also a European legislation requirement.
  • No pistons mounted on the brake pedal that could interfere with your feet or damage your legs in an accident.
  • No unsightly boxes mounted inside of the vehicle.
  • All components are mounted inside the vehicle and are not exposed to outdoor conditions.
  • No on/off switch means the system cannot be accidently activated while driving.
  • No bulky portable system to install and remove for each trip.
