Jonathan: It sounds like this might be a first time task for you. (I don't mean to challenge your abilities, but if this information is helpful I am glad to give a couple of tips.) Three things come to mind: a. Be sure to "bench bleed" the master cylinder before mounting it on the firewall. (Google - "How to bench bleed your master cylinder"). b. The reservoir/brake line closest to the firewall (the rear most reservoir) is to be plumbed to the front brakes. c. The reservoir/brake line furthest from the firewall (the one closest to the front of the car) is to be plumbed to the rear brakes. Good luck and keep smiling. >From Big John Mc Adams (In SoCal) From: Chrysler300@xxxxxxxxxxxxxxx [mailto:Chrysler300@xxxxxxxxxxxxxxx] On Behalf Of Jonathan Sacks Sent: Wednesday, August 15, 2012 2:35 PM To: Chrysler300@xxxxxxxxxxxxxxx Subject: [Chrysler300] brake system rebuild question Hi folks, I'm finally getting around to swapping out all the brake lines on my 66 - 300 and changing from a single master to a dual line. (Yes, that's right I've got 46 year old brake lines - talk about tempting death!) I've got the new stainless lines from Fine Lines, but I had two other questions for everyone, if I may. Thanks as always. You guys are great! 1) Does anyone know where I could get the rubber parts of the system? I'm thinking specifically of the part of the brake system above the differential that looks to be rubber. And of course any other parts I don't know about yet? (I haven't gotten my hands dirty yet on this one, so not sure what's what.) 2) Do you think I need to install a proportioning valve? Original system didn't have one of course, and I'm not switching to disc brakes (the drums have been great). 3) Do I need a different distribution block for the lines from the MC? Just trying to puzzle out in my head how the two systems are going to interact at the distribution block. Again, thanks a million! ...j Jonathan Sacks 66-300 (non-letter!) member since I can't remember...
