Torch for freeing stuck bolts.

[Clone TIE Pilot]

A ABS sensor went bad on my pickup, and I can't remove the rotor to reach it because the caliper bracket bolts are rusted shut. It is going to take a torch to free them, not sure if a Bernzomatic Mapp/Oxy blazing torch would be enough or I should get a O/A torch?

Map gas should get it I use it more than the oxygen acetylene torch map gas might take a 1min longer

MAP should definitely work.

Can you get an impact on them?

For tight jobs I used a MAP/propane torch, for bigger jobs I have this: https://m.harborfreight.com/portable-torch-kit-with-oxygen-and-acetylene-tanks-65818.html

The later works well when you lose your poop and decide you need to kill it with fire.

I use the MAP for almost everything these days just because of its convenience. However, it wasn't hot enough to get the damned LBJs out of my Silverado; had to break out the white heat for that. I read somewhere that MAP is about 200 degrees cooler than straight acetylene.

I use a Bernz O Matic first just because it's quicker and less to fire up. But if it doesn't cooperate, then the blue wrench gets the call.

Berms O Matic here, for most jobs
