add a chain tensioner so when you give it the beans, the chain will stop slapping and dancing around at high revs and popping off. also posting a picture of what your dealing with helps alot too. :rolleyes:
I had the same problem you just have to really wrench down on the bolts a little on each of them. They all have to get tightened kinda at the same evenly. Now the don't move and all I ride are bumpy off road trails.
i made my own brakes for my trike from https://www.mfgsupply.com/ i just bought the parts. they are heavy duty! here is my order so you can look up model numbers of the parts in the search box on the website. :) Hope that helps ya out..
