If you have access to an Oxy/acet torch use the smallest tip you have and carefully get it to glow then immediately quench with wd-40 or some other lube in a spray bomb......then use vise grips and just wiggle slightly.....if no luck repeat over and over till it loosens......the trick is don't heat up the wheel cyl just the bleeder(cool off with water if too hot)......the wiggle will allow the lube to soak in......Finish off new bleeder with neverseize...:thumbsup:
