See: http://www.jholst.net/55-service-manual/brakes.pdf Pages 86-97. Best left to pro's, methinx. I have used these guys with success. They are able to obtain or make needed parts. http://pwrbrake.com/ C-300-K'ly, Rich Barber Brentwood, CA From: Chrysler300@xxxxxxxxxxxxxxx [mailto:Chrysler300@xxxxxxxxxxxxxxx] On Behalf Of Warren Anderson Sent: Saturday, September 01, 2012 4:28 PM To: Chrysler300@xxxxxxxxxxxxxxx; Ron Waters Subject: Re: Re:: [Chrysler300] A serious 55 Kelsey Hayes issue - brake failure I would think that it would be somewhere. Is it in the shop manual ? Ron, In my opinion, the power brake system is covered nicely in the factory manual. Parts for it are hard to find. For that reason, I put a retrofit booster and master cylinder assembly on my car and it worked very nicely. The original pieces will fit back on the car when I find the proper parts (if ever unfortunately). The 'kit' to do the conversion came from Andy Birnbaum Auto Parts (SP?) long ago. It got me running at the time without a lot of work. But, something I definately did not want to do to my car. Some day, all of our old iron will have complete retrofit later model disc brake systems as parts for them will eventually be absolutely not available. Once again, my opinion.
