Twice now I have accidentally locked up my rear brakes on my 16 Street Glide. They were not panic stops at all. I don't know if I just need to get used to the feel of them or maybe better pads would help? Guess I should have got ABS!

 

Seeing as it's a 2016, the obvious answer is to take it to the dealer for a warrantee checkout. I did end up changing my rear brake pads on my 2015 SG because of the squealing. Lyndall pads made it nice & quiet.
