I recently acquired another 1970 Dodge convertible. The car came equipped with all the round drum brakes. The brakes work well at high speed but not at low speeds, so my plan was to have the power booster rebuilt by Booster Dewey. It now appears that there is a slight brake fluid leak too, between the master cylinder and the booster, so I might as well rebuild or replace the master too.
@DocMcNeedy has had good experiences with Midwest Power Products in Morris, IL. So, one possibility would be for me to send what is on Regina (PB and MC) to MPP, have them both rebuilt, and hope that the result works.
However, and this is the reason for this thread, the MC shown in the parts manual and the one in my car look different. Regina's master looks like a 1969 unit or (maybe) a 1971.
Regina (DL27L0D148841):
1970, as per the parts manual (scans of the latter were made available by MyMopar.com):
1971, as per the parts manual:
My worry is two-fold:
1. that the booster and the master might not work well together even after being fixed, if they were not correct for the car to start with;
2. even if everything works, it would still not be the correct equipment -- but I'd be out 3-400 bucks for the rebuild. In that case, rather than pay for a MC rebuild, I might as well buy the Raybestos MC36221, which is not correct for my car but which I have seen on numerous 1970 Dodges (and is the kind of MC that was installed during restoration on Poppy, another 1970 Polara 'vert of mine, on which it works very well).
Here is a view of Poppy’s braking (DL27G0D170979) when she was for sale; the master has since been replaced, but I still have her original MC on a shelf at home:
Regina was built on Oct. 31, 1969; Poppy was built on Dec. 4, 1969. So, it is not a question of Regina's being a "late build" and therefore looking like a 1971. It might be a question of her being a fairly early-build and having something that still looks like the 1969 MC.
With this in mind, I searched yesterday for pictures of fusies with seemingly original masters and boosters. Well, I have found several on FCBO that look like what the parts manual shows -- but also several that look like Regina!
--> I'd love to have folks whose cars still have their original 1970 power drum brakes post pictures of their cars;
--> it would also be great if folks who have a setup looking like Regina's could share pics of their rigs, and the story of what changes have been made over their cars' lives (assuming they know);
--> finally, if I were to rebuild the booster, is there any risk that the Raybestos MC36221 might not work?
For comparison, here are a few master cylinders on other 1969 and 1970 model-year P/D/C cars:
CE23G9C160090 -- 1969 but MC looks like Regina's rather than 1970 in the Parts Manual unit:
CE23L0C268284 -- 1970 whose MC looks like Regina's rather than 1970 in the Parts Manual unit:
CM27T0C169137 -- 1970 whose booster and master both look just like Poppy's and those in the Parts Manual -- but not like Regina's:
CM27T0C222965 -- 1970 whose MC looks like the 1971 in the Parts Manual (not Regina's, not Poppy's):
