1962 300. 12" rear drums. Previous owner redid the brakes. One rear side the cylinders look over extended and are pulling the outer rubber covers off. Other rear side the cylinder came apart but it could be from a botched installation.

My question is are the 11" and 12" wheel cylinders the same? I can find listings for 11" cylinders but the suppliers say those are no good for the 12" on my '62 300. I can find 12" shoes easily though. For example Rock Auto lists the 12"shoes but not the cylinders for 300, yet it lists both cylinders and shoes for the 11" rear on my Newport. Same story all the other places.

Thanks for your help.

Sean

Thank you! Napa shows the 32555 cylinders as not a fitting part for the 300, which is so odd. I think I'll just order them and take a look. In my imagination it seems an 11" cylinder would be different part from a 12" cylinder. But certainly willing to admit I could be wrong. Thanks again!

The same story for the 1960 300 as for the 1962 300 at Rockauto. When you look at the NY of the same year, the full table of brake cylinders apears. For the 300 only a fraction.

When I look at the 1960 factory parts catalog (chapter 5), the same part # was used for all 1960 cars and all brake cylinders, from the Dodge to the Imperial independet of the brake drum diameter.

Happy Restoring!

If they are over-extending, it is usually caused by using a drum that is too large of a diameter. Your drums may have worn too big. Measure them and see if you need new ones.

I checked out which rear wheel cylinders were used on the 56-58 12" brakes. 1409 973 seemed to be the one. Then I googled "1409973 Rear wheel Cylinders" and came up with a few hits, including a link to a FL thread. Looks like the forum has been around this block before. You need to read through the thread:

http://www.forwardlook.net/forums/forums/thread-view.asp?tid=57103&...

One of the key points seems to have been made by Dieter:

di_ch_NY56 - 2015-04-18 5:17 AM

What puzzles me very much is that back in the time of the FLK era there were two different brake cylinders for the pre 1959 FLK cars and the past 1959 cars (1409 973 for 1956 and up cars and 1857 051 for cars with 3 platform brakes).

When I'm searching at google for each of these numbers I get pages (most of all - even Rockauto) who proposes the W or WC32555 as the proper replacement. Rockauto for example shows in the table that the brake cylinder WC32555 (Raybestos) will fit 1956 to 1962 Chrysler cars - except 300 (only until 1959). No brake cylinders available at Rockauto for a 1960 300 by the way. Another page addresses the W32555 for the replacemet of both old (original) parts numbers.

In my opinion there is a big fault in the cross reference table when I look at the pictures of the issuer of this thread.

Happy Motoring!

Dieter
