Seized caliper bolt on 928 S4
One of the 10mm allen bolts on the passenger-front brake caliper of my 1988 928 S4 appears to be seized. Despite soaking it with Liquid Wrench overnight, I can not break it loose without rounding off the the corners of the allen head. Do any of you have any helpful suggestions as to how I might be able to break it loose?

smack it, try heat, try an impact driver (you hit it and it turns), try some other flavors of oil, PB Blaster, Kroil, worst case take it to a shop that removes bolts.

Two approaches. Get an allen socket wrench and try an air impact at low setting to vibrate it out.
The other method would be to drill out the allen head, remove the caliper and then you can work on the stud with oil and a stud puller
