Hi all. I did almost the full brake system on my truck yesterday. The only thing i didn't replace was the Left front Caliper. I tried to bleed the system and couldn't get the bleeder to open on this one. How do you guys get a stuck bleeder open????? I stripped the hex's off the plug and got a vise grip on it and it still wouldn't get it to budge. I used a good penetrating oil and even put a little heat to it with the torch and it still didn't open. How do you get these stuck bleeders open???? I thought about welding a nut to it so i could get a socket on it. Do you think if i keep messin' with it by welding the nut on it, will the heat screw up the caliper??? this one was working ok, so i didn't replace it.
thanks for the help guys.

easy outs or left handed drill bits! use the biggest you can as the small ones tend to break....then you will have to get a new bleeder screw but that's like $1 or so
You can always try a screw extractor... you can help it by mildly heating up the caliper and cooling down the bleeder screw. If all else fail, there's always caliper replacement.
I've had good luck loosening them by smacking the bleeder screw on top with a hammer at the same time that I have a wrench on it pulling, using a good closed end wrench so it wouldn't slip. I'd always try that first and if that didn't work then some heat from a torch would do it. If neither one of those tricks works you might be looking at a new caliper.
The simple logic is that if one wear part is going, or gone; it's counterpart isn't very far behind. Of course, there's exceptions, variables, and probably some pretty good technical explanations.
For me it's cheap insurance, consistency, and peace of mind. The Mrs. expects to hop in anything we own, go any place she wants, AND make it home without worry or incident. Sounds reasonable to me. After all, I'm the resident gearhead, not her.
have fun, Mike
PS, I'm surprised no one recomended tightening a little to break that crusty thing loose.
i agree, dont waste anymore time on it, just get another caliper and be done with it, then you will have a COMPLETELY new brake system, the calipers are not that expensive anyway.
Because different calipers of different age, exposure to elements, amount of use, amount of internal wear, etc., not to mention potentially different manufacturers and different materials, will have different performance characteristics.
In other words, don't complain when your truck pulls to one side, or wears pads out unevenly.
Rotors and drums are the only parts you don't have to replace in pairs.
