VOLVO VNL 630 2016 - 2nd trailer brakes overheating(is it my truck or is it jb hunt trailers?)

Hey guys im new to the forums and i hope you guys can help me figure this out!

i have a 2016 volvo vnl 630 with a d13 engine. 670,000 miles on it, maintenance up to date. Only thing i can say bad about my truck is i have to put 1/2 a gallon of coolant a week during the summer but im suspecting either my injector cups or egr are the culprit for this. I drain my air tanks daily and minimal amounts of moisture comes out of the tank which i believe to be normal. My big issue is that yesterday i picked up a 39000lb load of cooking oil on a jb hunt trailer (hjbt) and my trailer brakes started smoking and cause a fire on all four trailer brakes and popped 4 tires. I didnt think there was anything wrong with my truck until i started pulling another jb hunt trailer and those brakes started overheating and one tire popped on that trailer due to the excessive heat(rear right trailer brake overheated and popped tire). I checked my air lines and they all seem to be working fine, i even changed them just in case but i just want to know if there is anything else i have to check in case my truck is the issue because i dont want this happening again. I know jb hunt trailers are junk because people dont take care of them but having 2 trailers go through the same issue has me almost believing my truck is the issue.

please help!!

thanks

Above is a link to the second time i had trailer brake smoke

 

I always do a regular tug test and a brake tug test on all the trailers i use and everything seemed to be fine when i picked up the trailers in both instances

 

i had to open up the brakes on the trailer all the way using that bolt on all sides in the second instance just to get home

 

Im pretty sure it was the brakes because when the roadside guy came over to change the popped tire at 3am last night i saw that the brake pad was completely shattered on that side and it looked like it was due to the heat

 

I had enough air to release the brakes but to get home i mostly used my engine brake just in case because i was only 1hr away from home. I had a mechanic check my truck just in casee but he was unable to find anything wrong with it so i just wanted to ask through the forum in case anyone else had an idea what i could check on my truck because i dont want jb hunt to try saying my truck is the issue because of 2 back to back road services hours apart
