HELP!!
Both bleeder valves (regular screw-in types) on the front brake calipers are rusted, busted, and broken. One of them is mostly intact but the previous owner used a freaking wood screw to close it. The rusty screw broke off at the top of the bleeder valve. The other bleeder valve is rusted and mostly crushed from where I tried to loosen it using a pair of vise grips.
Do gas torches work? I can get one for ten bucks. I don't want to damage the caliper or the piston since OEM calipers are $300 each. I could probably replace them with generic brake calipers since they're mounted to brackets that bolt to the front forks.
I was considering using a high-wattage soldering iron to do spot-heating because it could fit inside the bleeder valve (well, the one that doesn't have a screw stuck in it). I'm concerned it wouldn't be hot enough to loosen the valve.
I could just drill out the bleeder valve, but I don't know where to find over-sized bleeder valves for this bike.
