Well i need to know ASAP please, what is the size of the caliper sliding bolt? Its an allen screw, and I have narrowed it down between it being 9mm, 11/32, and, 3/8. Someone please help, im working on it now and need to know so I can go out and buy the right size allen wrench.

 

I believe its 9mm....but you can get a combo kit that has both Metric/SAE in it for like $12.

 

Calipers without seperate brackets, I believe 99 and previous, me thinks are 3/8" allen...00 and newer with seperate brackets that the pads sit in are T45 or T47 torx bit

 

Yea, I have a '99 2500 4x4, and It was the 3/8", thanks for your help guys.

 

Glad to help. [sm=deal.gif]
