Advice Needed on frt otor replacement

[whodat88]

I need some help and advice, please.  I have a 01 2500 Cummins, and need to replace the front brakes and rotors.  There is a fairly large torx head bolt holding the brake calipers onto the hub assembly.  NO ONE has the External socket that fits this bolt.  Where the h*** do I get this socket?  I have spent two days getting nowhere but frustrated looking for this.  An E24 is just a little bit too small and that is the largest that NAPA sells.  Also, what size is the internal Torx that removes the caliper sliders from the main caliper assy?

 

thanks for any and all replies!

My caliper bolts on the 99 are Allen Head

The regular torx head bolts that hold the caliper to the bracket I believe are a T45 or47. You don't need an external torx for the other two that hold the caliper bracket on, a 12 point socket fits just fine. I believe it's an 18mm
