I am changing the breaks on my dakota. The drive side use a 6 sided key wrench. I have bought both standard and metric and none of the fit the bolt. It seems like it is in between 7 and 8 metric. Does anyone know what the hell is going on.

 

i believe its 7mm, if thats still too small, check to make sure its not damaged, otherwise try to jam a standard allen key into that bolt. gotta improvise to get schit done on hard worked vehicles. almost blew a hole in my leg a week ago removing the lower ball joint on my truck. word of advice: dont hold a torch to the ball joint longer than a minute.
