2000 silverado front brake calipers

can someone tell me wht kind of bolts hold on the front calipers,torqes head or allen head.thanks

pretty sure its a hefty-sized 'torx' bit, or whatever they call it.

to update you the caliper bolts are torx bit, the bolts you undo to swing the caliper up/down to change the pads. the MOUNTING bolts are hex head.
