Anyone have any ideas about removing a stuck brake caliper slide pin that doesn't involve using a propane torch? (auto, best)

[Zhang Fei]

I have no experience with propane torches and am a little concerned about ending up in the emergency room. I've tapped the face and the sides with a hammer to no avail, but did not apply all that much force for fear of breaking the top part off and leaving the bottom part stuck in the caliper.

Get some Kroil penetrating oil, if you can't find that, PB Blaster is about as good and you can get that at Wally World.

That said, a regular propane torch is not that hard to use without killing yourself. You will want some good safety glasses, maybe some leather gloves. Propane torch is a pretty cheap and handy tool.

You can use both heat and penetrating oil, heat the part, let it cool some, then apply the oil.

Would not be a bad idea to have a fire extinguisher handy when doing this sort of work. Put it in the trunk of your car and keep it there, better to have it and not need it, than need it and not have it.

Use a screw driver as a punch with some good penetrating oil like pb blaster.

I am actually not sure, what is the problem. On some cars, there is a bolt screwed into the guide. THAT is what holds caliper in place. I have several cars that if you don't know it, you'll be spinning that bolt forever, as there is a backup nut on the guide itself, that has to be grasped with a spanner or vice grip or channel lock, to secure it in place - then bolt loosens.
You sure?

Get a repair manual for your car and follow the instructions for removing the calipers. A few bucks for the proper procedure is cheaper than replacing a damaged caliper or upright.

Get one can of this, that's all you need.

If you don't want to use a propane torch, use a MAPP gas torch.

Honestly...at this point, i just replace the caliper. Most often when i free a stuck pin, it just reooccurs soon after despite my best efforts to clean up the pin, replace the rubber boot and regrease.

Unsure what car you have, but I just recently replaced a caliper on my car for $50 plus core. To me, that was well worth the time vs trying to free a stuck pin

Buy a matched pair of loaded calipers. They come complete with pads, etc. Bolt em on, attach the flex hose, bleed and drive. No fuss, no muss, and not that expensive...

You'll never get a slide pin out that is seized without heat. No penetrating oil will make it budge don't even waste your time. Get a new bracket and slide pins and lube them heavily. I always replace pins every couple years anyway. The low cost for them is a no brainer.
