What tools does it take to remove the front brake calipers? on 1992 Buick Skylark

I am trying to replace the front brakes but can't get the calipers off what tool does it take to get the 2 bolts out?

I cannot see from the manual or illustration and do not have a vehicle on hand to reference personally.

However, consistent with similar vehicles, the caliper bolts are probably removed with torx bits. Like a T-45. Hard to say though. Could be a hex bit as well.
