A great many people will be sceptical concerning the use of trailer brakes to conrol snaking. However, I did a similar thing in the mid 1950’s.

The above BSA 650cc twin cylinder motor cycle and side car had an independently operated cable  control to the drum brake on each wheel.

To negotiate a right hand bend I often had to apply the front brake only, and for a left hand bend, particularly with a well loaded side car, it was often necessary to brake the side car only.

For normal straight line braking all three brakes could be applied at the same time.

It is now not legal for the driver to brake a trailer independently of the tow car, but the law does allow this to be done  electronically. This cannot be done with over run brakes (without an electric/electronic modification), but it is possible if the trailer brakes have  pneumatic, hydraulic or electric control.

Bath University have shown in wind tunnel tests that aerofoils producing downforce improve caravan stability, and if independent trailer braking is electronically  used as well, the maximum safe speeds I have estimated can be increased.
