Morning all
Can someone please help with the following question.
How do you reverse a caravan when the van has an override brake system ?
I have never even thought about this until my brother asked me.
Many thanks!

In reverse the brakes are very poor.. ican reverse the van with movers with handbrake engaged, the resistance to move is much lower, but when I need to turn an take it forward, it brakes basically lifting up the van, then I remember the brakes.. same with vehicle, it will reverse with less resistance, so it works.. but having a safety pin for reversing works even better

Caravan brake has drop down shoes on the rear to allow the brake to fail in reverse, it will however pick up in the forward motion. Therefore be careful when pushing a van downhill by hand as the brakes will not hold the van unless it is set properly with the hand brake pulled up all the way.
Do it now or leave it.

Older vans had a revers spacer or lever and hook that had to be engaged before you could reverse. The over run brakes nowadays works as explained above.

Remember to pull handbrake fully up like it is actually vertical to ensure it works in the reverse direction. Also very important that the brakes are set properly. (Maintenance)

As explained above...to be absolutely sure when reversing downhill NEVER unhitch the van without putting something like a wedge behind each wheel, the van may just take off all by itself! (even if adjusted perfectly, remember that nasty Irishman going by the name Murphy...he may just be in the vicinity!) If the brakes do lock when reversing they are not adjusted correctly, they should allow the brake shoes inside the drum to drop away from the drum when pushing back.

Go to following link to see document on how the over-run breaking system works and how to adjust them correctly.

Biscuit, Something you might take note of: Because of the fact that overrun brakes only brakes when the caravan moves forward as explained by other members, this makes it possible to manoeuvre the caravan backwards in situations where it is difficult to do this with the tow vehicle, especialy on a slight incline where muscle power is not enough. You pull up die handbrake and then swing the caravan from side to side, say about a meter to each side. What happens is that when you swing to the starboard side, the wheel on that side will move backwards while the port one will be braked and thus stay stationary. When you swing to the other side, the opposite happens. This way the caravan moves backwards in small steps. It is quite easy to do on your own. A lenght of pipe, about 30 cm or so, with a hook that can attach to the safety chain also helps with this.

Here is another link to a file containing a more detailed description of the operation and set-up of the brakes.

https://drive.google.com/open?id=0ByJeiRsLGnPjTXB5YnJMN1lLekE


According to the information given, you should be able to reverse your caravan up any incline without the brakes fully engaging - from what I have read on the forum, this is not the case with many caravan users who state that the brakes bind if the incline is too steep.

If the caravan is able to run backward freely, the hand-brake will only work if it is pulled up vertically or even past the 90 degree mark so as to compress the energy reserve spring which applies an extra force on the brakes as the caravan starts to run back.
Even after having my brakes set-up by an "expert", I am still unable to stop my caravan from running backwards by using the hand-brake. Have now fitted a caravan mover to help turn and park it in the sloping driveway.

Bruce,

The responses are correct, but I think they have missed the point.

When the caravan is in forward motion, ensure to brake softly so that the overrun brake does "not" engage - then you can reverse.

When these overrun brakes first came out, I saw a newcommer to caravanning get frustrated with his large automatic - pulled off at speed - jammed on the brakes - could not reverse. On calming him - pulled the caravan forward just enough to disengage - stopped slowly - reversed without a problem.

Leon's point on older caravans - most, if not all, spacers were spring loaded and jumped out when pressure was released (even while reversing) and caused the brakes to engage when reversing. Some fixed these spacers and left them without brakes when moving forward again.
