I am not really up on trailer brake controllers and bought a Redarc which I have not yet fitted.
Since then I have now learnt that the Redarc does not provide proportional braking to the trailer brakes in line with the effort being applied to towing vehicle brakes ie when breaking the braking effort on the trailer brakes is the same in a crash stop vs a gentle stop (can be adjusted on setup and adjusted on the move if required).
Is there any issue with this type of system compared to others where the braking effort on trailer is proportional to the braking effort of the towing vehicle - ie emergency stop - full braking effort is applied but when just slowing less braking effort i applied.
Advice form those in the know would be appreciated.
Thanks
Garry

I have no experience with
Redarc, so please read my reply accordingly
I have a Tekonsha (spell?) P3 which has proportional braking. Having experienced the faultless performance and differentiation between emergency braking (specially in wet or on dirt) and the softer braking in other conditi0ons, I cannot even consider ever going to a non-proportional system.
Hope this helps - not sure what your question is but this is my opinion

I wouldn’t have an automatic proportional brake controller.
To have the caravan brakes actuated by inertia caused by the slowing of the front vehicle is dangerous in some situations.
I have jack-knifed a trailer at speed with a similar system and it’s a scary experience.
With a manual system; if you get a wobble up you need to apply the caravan brakes first (by a light pressure on the foot pedal – not enough to apply the front vehicles brakes, but enough to actuate its stop lights).
This is especially important when towing a heavy load downhill or at speed over corrugations.

So you have never used a proportional brake controller?
Once you have used one you will never go back to a on or off controller again.
With the proportional brake controller you still have full control of the trailer brakes and you can apply them manually with the slid control.
What brand and model was the similar system you had problems with?

I know that you can set your auto controller to manual if you wish.
With automatic devices, people usually set and forget – in an emergency it’s too late to start fiddling with knobs to reset the device from auto to manual.
It’s also reassuring to lightly touch the pedal and feel the van brakes come in first when you’re belting along a corrugated road, towing a 3 tonne van.
This not a band bashing exercise - I have towed a 3 tonne van around Australia twice with a manual controller - wouldn't go auto for the reasons mentioned.
Not saying the auto doesn't suit a lot of people - its just not my cup of tea.

Dennis I think you really need to try one before saying you don't like it.
You have me lost on this resetting from auto to manual?
So what your saying is you would sooner have an old fashioned brake controller for 1% of the time as opposed to a new tech one for 99% of the time.
Dennis you really need to upgrade and try it.
A proportional brake controller will do every thing one of the old type will plus more and a lot easier.
As asked before have you ever tried the new proportional brake controllers?
An proportional brake controller is so much better in an emergency as it can alter the rate of deceleration to the situation and you can even change the delay of when it will come in.

We are only getting sidetracked here, I am not getting into a
mine is better than yours argument. It’s all about the method of actuation and I don’t like actuation by backpressure from the front vehicle in risky situations. In other situations I like the way the automatic proportional systems work. It’s a personal choice for me reinforced by a jack-knife incident at speed. We all have different priorities.

What no one has picked up on is the fact that a Prodigy can be set to come on as you like.
IE It can be set to come on slightly ahead of car brakes thereby applying the van brakes slightly earlier than the car.
This is advantageous in the situation where you may be in danger of jacknifing.
Who has 3 hands to pull on a manual control whilst trying to steer with one hand, maybe trying to change down with the other and what are you going to use on the brake controller...

I had one and replaced with a P3 after about 3 months and constant monitoring.
If you can predict in advance all types of traffic conditions, driver behaviour, road types and road conditions every time you brake then the Redarc is for you, but you will have to adjust it just before you brake.
Ditch it and get a P3. The redarc is dangerous IMHO.

Garry,
There is a lot of hysteria in a couple of the answers by people who are trying to justify their own choice.
Be assured, the Redarc brake controller works very
well, in all types of braking situations.
I also have the remote head unit recommended by a camper trailer distributor who use the same unit on their triple axle transport trailer that carries three campers at a time.
I'm not sure how many people use the "backup system" that should be available.
My camper has electric brakes, with a hydraulic override system as a backup.
You should always leave the latch open, so that the hydraulic override brakes will operate in a situation when the electric brakes malfunction.
In normal situations, they will never operate as the electric brakes will be activated before inertia operates the hydraulic coupling.
My previous camper only had the hydraulic actuated brakes and worked OK, although with a noticable "jerk" of the mechanical coupling, mainly when accelerating again after braking. The Redarc controlled electric brakes when adjusted correctly, will operate smoothly and effectively in all situations to apply braking force to the trailer, camper, or caravan, thus assisting the vehicle brakes to slow down and stop the rig effectively.
You have selected an effective electric brake controller mate.
Bill.
