Re: [Chrysler300] Disc Brakes - 1962 300

I did the same as Charlie six years and 6000 miles ago on my C - AAJ front discs only and stayed with the single master - and I am really pleased with the outcome too. I went with all new hydraulics throughout the brake system, and I am trusting the single master as there is no plug-in dual master that will fit without an engine interference in the '57-'58 hemi cars. The car stops smooth and arrow-straight every time - even right out of hibernation. I am using DOT 4, and this reminds me it's time to change that out and see if I have any moisture or beginnings of rust in the system.

I did find it necessary to tinker a bit with the AAJ-supplied proportioning valve to get front and rear skidding the same. And I also ended up installing a check valve on the rears (I don't remember the exact psi) to keep the rear shoes from releasing too far..

I  installed the AAJ kit on my 62 300 sport convertible about 10 years ago. I just bought the basic kit for the front brakes from AAJ.  No sense paying for shipping , 3000 miles, for the heavy parts when the rotors and calipers can be bought at your local parts store. Got all my stuff at the local Napa.

I stayed with the original master cylinder and it still works great.

H Charlie; I was very impressed with the full kit . Very well done . JY Chouinard had told me he had good success too . So I followed his lead . At first I was tempted by the minimal kit, for 300F ,  but with  deluxe kit all the running around is avoided , every part from wheel bearings,  rotors , spindle  adapters , even hoses fittings etc is included . It may be several hundred dollars more than the ones you see advertised but worth every cent . The machined parts like spindle wheel bearing spacers / adapters are simply beautifully made ( spoken as engineer) . AAA++++ from me . 

Buying another one for front of 57 dodge shortly . 
While I know they can be made to work ok , total contact front brakes can drive you crazy . Perhaps best described as very innovative , effective , smart , but as a result fussy . And rust in drum after sitting over winter often causes dramatic lock up in spring due to the two leading shoes .. ( arrange so you back up , and brake first!) . Took me a while ( many years) to “get” that . You at first think brakes went bad over winter . 
Plus maintenance / parts looking ahead. I find myself moving to front discs. Slowly . And silicone fluids..

Hi Group,

I know that this subject has been brought up several times in the last while, but I'd be interested to hear from members who have installed an AAJ disc brake system (2 or 4 wheel conversion) on 1962 models and any comments you may have. My research seems to indicate that if there are going to be issues, that it will be the master cylinder. Looks like pre - 62 models use a different master cylinder due to it's location under the booster.. The actual disc brake hardware does not seem to be that great an issue. 

Happy New Year to all.
