Robbin, Ask ANYONE that knows me - I am about as sharp as the combined total intellect of my 3 dogs (that could be pushin mid 60's on the IQ meter there) I just had a lot of trailer brake fixing and towing in past life. I used to like banjo music, even played WITH one for awhile - I have little room for the racket anymore. (Abigail Washburn & The Sparrow Quartet if I must listen) Electric trailer brakes are fine on terra firma and are controllable from the cab of the truck while texting on your smart phone,and deciding if it is better to 'go in the ditch or hit the station wagon', actuate trailer brakes, swerve, oh sh*t -over 140 characters, - slam on brakes again,watch out for coffee cup on iPad, BOOM. damn. Hydraulics in proper service condition - hit the brakes- slow down. Slow down B4 we need to hit the brakes is really the key here. Water has a tendency to 'interrupt' electric current on its way to the solenoid poised with the task of actuating your brakes - corrosion from launchings makes it a game show. The city bus driving by the scene has the name of the Accident/Injury attorneys that will be contacting you soon. Take Care, Use Hydraulics, Have Fun,Go Sailing GO PS -I will "re-distribute" the SCA mags collection at the next LHPCC - first person that _________, get's 'em! Whadda you think??
