rick, I put Tie-Down SS Discs on all 4 wheels years ago, B4 TD made an actuator(coupler)...at the time I had to use an Attwood coupler which caused MAJOR problems...since I've changed it to a TD 6000 actuator and had no problems, but one thing you MUST understand: the damper in the actuator fills from the brake-fluid reservoir(it's NOT self contained like a shock-absorber)...TD has a new Eliminator series brakes that look much improved over when I bought...

Suggestion, look closely at calipers when installing for when you'll have to replace pads and go ahead and get an extra set of pads when you buy the brakes...you may not have the luxury of shipping time when you need to replace... ;)...

Elec/Hydraulic is for rigs bigger than ours and you'll just be bitin' off a lot of extra BS you don't need...system above will do you fine...no experience with Kodiak, but I hear they are GREAT HD brakes...price and check into service for both B4 U decide... ;)...
