Well it isnt the pinch bolt, its the one on top of the TRE, the one that pinches and goes through the groove of the TRE is there and tight.

 

K so i replaced the TRE and it still pops, and i figured out that if the road is rough enough, or sometimes randomly it will pop without hitting the brakes, although it seems it does it much more often when im pushing the brakes.. So is everyone thinking its struts then?? any other possibilities?

 

Bump, will the pop become almost constant if i leave this for a while?
