In case any of you'll have contemplated to possibility of retrofitting your RV brake system I thought I'd offer my experiences.
About a year ago (+/-) "Trailer Life"
had a great article on retrofitting from drum to disc brakes. I read with great interest the obvious advantages of such a changeover.
I have a 34" Cedar Creek which I've towed to Dawson City twice and Key West once plus a variety of other places. I have always been aware of the constant need to maintain an appropriate distance from the vehicles in front of me should as well as watching 3 to 4 vehicles ahead in order to anticipate a "panic" stop. Unfortunately, maintaining a safe distance insures the fact that some ***** will feel the need to fill in that spot being totally oblivious to the fact that a big, heavy vehicle is following him/her.
In any case I've, been forced to make my fair share of "panic stops" in order to avoid a rear end collision. (We've all been there!) Even though I drive a 2011, Ford, F-350 I've had to on rare occasions stand on the brakes to avoid a collision. I should also mention that my TRV brakes are (were) up to snuff and were in good working order.
Considering all the above I decided to make the change over and what a difference. The disc brake system is electric over hydraulic. By that I mean that an inertial electronic system tells the hydraulic system how much brake pad pressure to apply. When the breaks are applied now I honestly don't feel the trailer pushing me and am almost not even aware that there is a trailer behind me. It has made a vast difference in our traveling peace of mind and I wholeheartedly recommend the change.
