Just realized two very different ways to handle a seized caliper bracket bolt

I had a 2002 Camry in the shop last Thursday. The left rear caliper bracket bolt was completely frozen, seized up like it hadn't been touched in 15 years. I spent 45 minutes with a breaker bar and penetrating oil, finally got it loose but almost stripped the head. Then my coworker Dave walks over, grabs his induction heater, and has it out in 3 minutes flat with no fuss. Now I'm wondering which method is better for the long run: the brute force approach that risks damaging things or spending money on a tool that might only get used once a month. Has anyone else debated this and settled on one way?

My buddy tried the heat gun approach and melted his brake line.

Reminds me of the time my cousin tried using a blowtorch to loosen a rusted bolt on his truck. Ended up setting the undercarriage insulation on fire and had to roll around in the gravel to put it out. The brake line thing sounds way worse though, at least his truck still ran after we got the flames out.

Jumping off what Felix said, melting a brake line with a heat gun is a real quick way to turn a small job into a big one. You figure a little bit of heat is enough, but then it gets into that rubber hose or the line and now you're bleeding brakes and replacing a part you didn't plan on. The induction heater is safer in that sense, it's more controlled, but then you're looking at a couple hundred bucks for a tool that sits in the drawer most of the time. I guess it comes down to how often you deal with rusty bolts. Either way, Dave probably saved himself a headache that day.
