drum brakes will never give you the same feeling as your truck. As stated in other post they grab good at low speeds but dont have enough power at highway speeds. My trailer had 7000lb axles under a trailer that weighed 16,500 +- 500lbs , I have been on the scales it was just under 13,000 on the tires but that wasnt a issue. Part of the problem is the wire size from the front of the trailer to the brake magnets was only 14awg , you get s good amount of power loss when you travel 60' from the power source and expect to get full voltage at the magnets. Having said that I didnt elect to fix that issue just knowing drums fade fast at highway speeds. I replaced the entire system with hydraulic disk from Kodiac. Now I have enough brakes at any speed I can feel the trailer stopping the truck id the gain is set over 7.5. I can safely stop the combo in about 225-250' from 60 , with drums that was closer to 400' and the truck did most of the hard work. Honestly it always left me with a uneasy feeling in stop and go traffic . disk brakes are a MUST on heavy trailer , 12" x 2.25" drums are fine on a 10,000 lb trailer but NOT at 17,000lbs.
