yes, that is a real danger and of course would be the garages fault as its their car!?
so, soak in penetrant and leave ( go prey for an hour ), come back and try to release the nipples with out them shearing off!
hot air may help.........if they shear off, use mig method, drilling as a last resort!!!!!!
mig method:
remove caliper from car and mount steady in vice, clean sheared off remains as best as possible and weld a blob to the sheared nipple in caliper, allow to cool and repeat. be care full not to weld the nipple remains to the caliper!!!!!!!!!
when blobs are big enough ( say 3 blobs ) weld a prepared bolt ( suitable sized bolt with a tapered end ) to the blob, and gently try and release......if it shears off try again.
ok, a different way......remove pads and pump out piston as much as you dare, clamp hose and undo a union a bit and push piston back in, repeat till no air comes out.
