I'm down to replacing the last wheel cylinder on my 1964 C10, and the fitting on the driver side rear seems to be rusted to the steel brake line. I can break the fitting loose from the wheel cylinder, but it won't spin on the brake line. I've been soaking it with PB Blaster and am using the correct line wrench, but so far no luck.
Any thoughts on breaking it loose without kinking and breaking the line? Maybe a little heat or trying to hold the brake line with vice grips...
