Don safety glasses, and use a propane torch to heat the area on the brake caliper, where the brake caliper bolt goes into. Use caution as brake fluid is flammable. Keep the flame moving back, and forth, on the brake caliper area for the caliper bolt.

You'll have to experiment in this task. You won't be able to get this area cherry red, and you DON'T want to! Heat the area, tap on the area with a hammer, then try to remove the bolt. Keep doing this procedure until the bolt starts to move. See below for more detail.

You are heating cast iron, which expands more rapidly than the steel bolt. Now take a ball peen hammer, use the flat end, and TAP along the area you heated. DON'T beat on it, just medium taps.

Suggest you use the proper thread tap, and clean the holes of the brake caliper, and the proper thread die to clean the threads of the bolt, before reinstalling.

If it is the front main seal, and you are going to tackle the repair, you need to get a Repair Manual for your vehicle and follow the directions for the fix.
