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.

Recently Had Air Suspension fitted to our Elddis Sunseeker Motorhome The excellent Piece of Kit has we encountered a few uncanny moments reversing up to our driveway as we didn't catch it right on the reverse maneuver . ( ie Grounded or bottom out ) rear end. Explained all of the above to Tracey explained that chassis was a Leaf Spring ( Recommend the LEAF SPRING STANDARD AIR SUSPENSION KIT with COMPRESSOR ) . Installation took a few hours to complete . Upon collection we were shown how to operate the kit . When we drove home i noticed a hell of a difference in the road handling which was a great difference to before . And in Reversing up the Steep incline to our driveway with the suspension raised. We are very pleased with the overall installation and the excellent service we received From LNB Towbars & Vehicle Extras Ltd Of Bristol Would highly recommend to Other Motorhome and Campervan Owners Thanks again . Keep up the GOODWORK . Kind Regards John

We had an A Frame fitted by these guys and they are very professional, courteous and accomodating. Excellent customer service and brilliant product, Towmaster 2. We would highly recommend them. Not the cheapest but you do get what you pay for.

Had a towbar fitted yesterday on our new motorhome (this is the second time we've used LNB) and if anything the service is even better! We were booked in at 1pm and returned at 5 when we were told that it was almost ready but we could wait in their very plush waiting room with complimentary tea and coffee and biscuits and our dog was welcomed with a drink and treat. The job was completed to their usual very high standards and we can't recommend them highly enough. Pete & Jackie Henley.

LNB towbars came up trumps delivering me a pair of motorhome skid wheels the next day after another company took my money but had no stock. The Lady on the phone couldn't have been any more helpful. Amazing service and a shining example of how a company should be run. And if the MD happens to read this...the Lady on the phone should be recognised for the outstanding service she provided.

Fantastic service and friendly staff at LNB we travel quite a distance for this super service and was not disappointed. Room to park up overnight courtesy car during towbar fitting and a first class job finished to a very high standard. Highly recommend

Installed HPC Levelling system 2 years ago and just had air suspension fitted. All staff so knowledgeable and friendly, great experience throughout. Would not use anyone else. Clearly our dog agrees too.

Can't fault the service or facilities on offer. I had a bike carrier fitted to my camper and all went well. I was offered a courtesy car which I accepted enabling me to go elsewhere while the carrier was fitted. The staff were extremely helpful and friendly. I would highly recommend them.
