Hello 

Can anyone give any advice or help please. 

On my two four lane tracks we use the DS hand controllers, V2, at 45 ohm.  These have proved very good and reliable,  so far....

One of the controllers has lost its braking effect.   Release the trigger and the car keeps on running, instead of stopping almost immediately as usual. Not a sticking trigger, just no braking effect. 

I have the swapped the controller to each of the 4 lanes, and it is definitely the controller. 
All lanes work fine with any of the other 3 controllers,  and I have tried various cars.

Any ideas as to what has happened, or advice on possible fixes great fully accepted 

Thanks, 
Pip
