2026 Kawasaki mule 4010 4x4

Not sure what it is causing this. At first (0 hours-6 hours )all 4 brake drums were so hot after riding a mile or so without applying brakes at all that i could only touch them briefly before i had to pull my hand away, now only 1 does this the passenger side rear(currently at 12 hours). I took the drum off adjusted the brake so it had slack between it and the drum. Nothing looked damaged or anything put it back together and it still gets quite hot just like before. The brakes work fine i can spin the tire but it does have some resistance since its hooked up to the cv axle and connected to the rear transfer case. The mule can coast to a stop easily i can even push it. Im not sure what it could be at this point. Brand new mule first owner
