Jon89le Posted August 24, 2004 Report Share Posted August 24, 2004 Well after braking about 3 bleeder valves over the years, and having to buy a WHOLE NEW caliper, i decided to try something new. Mapp Gas. And it worked! I heated up my front bleeder valve with a can of Mapp Gas i have (propane im sure would work as well) and the valve pretty much almost came out by hand. I heated up the caliper housing, not the valve itself, as to not possibly fatigue the metal. Well this was just an FYI i figured id share. Maybe save someone some money later on down the road. Im off to try and repair the rear bleeder valve i snapped now Quote Link to comment Share on other sites More sharing options...
DiscoStudd Posted August 24, 2004 Report Share Posted August 24, 2004 Just gotta say, I hope the heat stayed around the bleeder hole and didn't transfer over toward the rubber boot around the pistons! Sounds like an excellent idea, seeing as Mapp gas gets hotter than propane does... Quote Link to comment Share on other sites More sharing options...
Jon89le Posted August 24, 2004 Author Report Share Posted August 24, 2004 I held the flame very close to where the valve was. The way i did it was i had my dad hold the torch while i turn the valve. To be honest the caliper barely got hot but it made the valve/fluid get warm. Quote Link to comment Share on other sites More sharing options...
GP1138 Posted August 24, 2004 Report Share Posted August 24, 2004 Isn't this similar to welding in order to repair a fuel tank, in that it's dangerous? I thought brake fluid was flammable. Or maybe it's just caustic. I dunno. Quote Link to comment Share on other sites More sharing options...
midnight rider Posted August 24, 2004 Report Share Posted August 24, 2004 Brake fluid isn't flamable. It is causic however. If you do this, wear a breather mask and work in a well ventalated area and work quickly. Quote Link to comment Share on other sites More sharing options...
Jon89le Posted August 24, 2004 Author Report Share Posted August 24, 2004 ^^^^^^^ What he said. I did this very quick. Held the flame there for maybe 10seconds and unscrewed the valve. The main thing is the Gas. Damn mapp gas smells aweful. Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted August 24, 2004 Report Share Posted August 24, 2004 I sure am glad I don't live that far North. I've never had a problem breaking a bleeder valve free. Quote Link to comment Share on other sites More sharing options...
midnight rider Posted August 24, 2004 Report Share Posted August 24, 2004 I sure am glad I don't live that far North. I've never had a problem breaking a bleeder valve free. I live south of you and have broke several of them. It all depends on the area you live and the amount of salt they use to clear the roads in the winter...lol Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted August 24, 2004 Report Share Posted August 24, 2004 You live south of me? Eldon is 124 miles north??? Quote Link to comment Share on other sites More sharing options...
midnight rider Posted August 24, 2004 Report Share Posted August 24, 2004 sorry, I spaced that. You're right..... I thought you were outside of Saint Louis for some reason Quote Link to comment Share on other sites More sharing options...
ron350 Posted August 25, 2004 Report Share Posted August 25, 2004 It is to bad some company does not sell a standard replacement stainless steel bleeder valve. Quote Link to comment Share on other sites More sharing options...
