Not sure the make and model, i have a 96 186 champion. I am assuming its the trailer that came from the factory. It has surge brakes but they dont work, so everytime i start and stop there is a loud clunk from the tongue compressing and decompressing. I dont know if this has something to do with it but the brakes didnt work before this happened but i accidently left the emergency line hooked to my truck and drove off, so its broke. What can i do to fix the brakes and where do i find the parts?
