Hi all,

I was reversing my camper today and heard a very loud clicking sound a number of times coming from the electric brakes on my camper, anyone know what this is? I have a Redarc tow pro elite FYI,

Best John

Did you have your foot on the brake? Electric brakes dont work in reverse and the sound your probably heard was just the actuator pendulum being moved backwards and resetting under spring tension

If unsure I'd pop the hubs off and check.

The electric brake should work in reverse as the magnet and arm are moved the opposite way and expand the brake shoes just the same. My Tvan ones worked in reverse and so do my caravan ones too. After all they are servo brake design with a floating bottom to auto apply after activation. That is why when adjustment is too far off they wrap on and stick on, sometimes pinging as they release when the brake signal is removed. It may be the electric magnet units are worn tapered and when activated in reverse they catch on the stud holes and ping and as it throws the magnet off the drum face they may release a bit and then instantly reapply. A check of the magnets and shoe wear is always a good idea.

The TowPro has two modes - one is proportional and the other isn't. If it's in the non-proportional mode it brakes the same amount each time you hit the brakes, no matter how fast you are going or hard you are braking. You can tell by checking the LED colour on the dial.

In non-proportional mode I've found that you get a loud clicking sound from the brakes as they grab/release. It doesn't do that in proportional mode because when you're going slowly & not braking hard it doesn't apply much power to the brakes so they don't grab as much.

What colour is the dial LED?

Yep, she was in non proportional mode and was glowing green, I think you have hit the nail on the head, cheers John
