I recently rigged my new hauler for electric brakes for my dual tandem. I'm not getting much braking effort out of the trailer and am trying to figure out where to focus my efforts rather than blindly start a seach and destroy mission form end to end.I know the brakes on the trailer work. When it went to pick it up, the truck I'd borrowed, wasn't a match with the trailer wiring and when plugged in the trailer was locked down tight enough the truck wouldn't budge it. Being the cheapskate I am, my brake controller is one I salvaged out of a dually from a friends salvage yard. Its a Valley electronic type and shows a '96 mfg date. It does show a green check light when the trailer is plugged in and I do have some trailer brake response. Its installed level, and I've adjusted all three (leveler, "hard" and "soft") of the possible controls with no decernable change in function. All the wiring is new and heavy guage from front to back. I checked the wiring in the plugs and the trailer ground goes straight to the brakes. I pulled a good ground into my plug on the truck. I'm trying to avoid just throwing the $$$ at it, but I'm wondering if the brake controller might not have the power to operate the big brakes of the dual tandem. Is there a lot of difference in different controllers ability to energize the magnets? My pickup has a big Teknosha electronic controller, and when not properly adjusted will make a tandem trailer (with one braking axle)hop, skip, jump and chunk you on the dash board. Grossing 30K now, I'd like to have something capable of that on this rig too. Another side question on this. Nowadays everythings done with electronic controllers rather than the hydraulic models I grew up on. Has anyone ever seen a electric brake controller that works from air? I know they have vacuum over hydraulic, air over hydraulic and now electric over hydraulic systems. Is there such a thing as an air over electric system? That would be ideal for me, but I've never seen one.
