So I'm an idiot, and too strong apparently. I sheared a rear brake bleeder screw. Thankfully no fluid is leaking out. But I'd like to get the broken part out pronto to keep what remains from rusting to the caliper. A look at Autozone's website shows they don't have the bleeder screw in stock. But they do have other GM brand bleeder screws in stock. So first, does anyone know what other GM brands and years share the same bleeder? I'd bring a good one in for comparison, but then my car would be left leaking brake fluid all over the place. Maybe I'll try going in with whats left. If that cross referencing plan doesn't work I'll just take a drive to the salvage yard and walk a half mile to the Saabs (they keep all the imports as far away from the gate as possible). Second, how the hell am I going to get what remains out of the caliper? It sheared flush with the caliper surface. I suppose I could drill it out, but I fear that metal scrapings will be introduced into the brake system.
