I just recently found a single person modified air pressure bleeder kit utilizing the pressure from one of your tires. There are 5 adaptors depending on yur particular model. The system is called speedi-bleed. The website is as follows
www.brake-bleeding.com. This site is out of Canada. For the one adaptor system the cost was $119 US and for the complete Professional kit with all 5 adaptor ~$289 US. For a US location just type in speedi-bleed in a search engine and follow the sites. Check it out.
