I have on hand a 5lb Halon extinguisher in my Dart. Was told about 15 years ago that they were no longer available. I would like another one, so where do you buy them now? Had a rear brake lock up once and the drum was on fire from the fluid catching on fire from the heat build up. I had some beer in the trunk and popped them open after shaking them up and was able to control the fire from reaching the trunk and back seat.LOL
