Brake caliper bolts?

    Is this the way they're supposed to be? Is this another example of idiotic GM engineering? No wonder they went bankrupt. My front calipers have hex head bolts but the back ones have torx. WTF?? Of course I have a set of torx sockets that goes up to T50 (too small) and a single T60 I bought years ago for GM brakes (too big) GAAAA:grrrrrr:

    You should replace them with regular bolts.

    Go to Napa, I know they carry the hex head bolts

    That requires me getting them out which means buying another torx socket. I think I'll wait until the pads need replacing.

    Most stores will lone them out or actually let you borrow without cost (depending on what store you go to)

    Most the time if they are hex bolts then they have been replaced before. All the bolts that I have seen from the factory are T-55 Torx for the front and hex for rear calipers (on 1999-2006 models)
    Before someone jumps all over me for posting incorrect info, This is what I have seen on my 2002, 2003, and 2005 GM trucks, not to mention the multiple GM trucks belonging to friends and family that I work on. On my 2005 someone striped out on of the front caliper torx bolt heads. I was able to get one out, loosen the bracket, remove the pads and brake line, and then slide the entire caliper off. I heated the crap out of the bolt just because I wanted to see if I could get it out (knowing that I would probably have to replace the caliper because I was going to melt rubber), I could not get that thing out for the life of me.

    My 2001 is the other way around. What is going on with GM?
    My front calipers use TORX while the rears use HEX head. :grrrrrr:
