What size torx bit should be used to remove the caliper on a 1990 cadillac deville?

trying to change out the hub on a 1990 cadillac deville and thought that it would be a standard 3/8 allen bit but it's a torx bit. just wanting to know what size the actual torx bolt is. thx.|||try a T-50. that,s the size my oldsmobile takes.|||I am ALMOST 100% sure it was a T-45 but I cant remember for sure.|||Can't remember the exact size but you can buy a whole set fairly cheap.You never know when you might one to do something else.|||probs a t25/20/30/45
