NEED HELP!

[SIPLOWGUY]

A friend of mine has a 1970 Plymouth Fury with 4 wheel drum power brakes. He needs a booster. I reached out to a well versed 70 Fury guy I know near me. He had a booster, but it looks visibly different. He seems to think the booster (not the master cylinder) on my friends drum brake car is for a disc brake car. He even confirmed the booster he has is the same as his 70 Fury 4 wheel drum brake car. The first photo is on the 70 Fury near me, the second photo is on my friend's 70 Fury. What does anyone think and who may have the one like the second photo?

The second picture is the somewhat common (to me) Midland-Ross booster that was used on a huge amount of 1965-1967 (maybe as late as 1968) C-body cars with drum brakes. At the time, they were common as everything. This was also back when the power front disc brake cars had the similar, but longer, dual diaphram boosters.

In some cases, Chrysler did use a different drum brake booster, as I recall seeing in the FSMs. Different manufacturer, BUT the same master cylinder. Which means that as long as the master cylinder is there, the booster than runs the master cyl might be variable. Goes in the same place, same function, bolts to the same bolt holes in the cowl, etc.

Please remember that rather than to go by the word of others, you can invest some time in some Factory Service Manual investigations. www.MyMopar.com has the factory service manuals for free download. Takes minutes. Plymouth, Dodge, and Chrysler FSMs. THAT can be your best source of information in this area. THEN you'll know what you have and are looking for.

A secondary source of information can be www.RockAuto.com. Pictures of the items, plus charts on model, model year, and brand usage of each part they sell.

Between BOTH sources, you can generally get things pinpointed very well, as to usage and such.

Enjoy!

There is no dealer stock on either of those boosters, you will need to current booster rebuilt. www.powerbrakebooster.com does a good job rebuilding them. The first booster appears to be a Bendix single diaphragm booster, as noted the second one is a Midland-Ross booster. Those are both drum brake boosters.

Mopar used both Midland (pic 2) and Bendix with single and dual diaphrams (duals were disc)....the booster rebuild kits fit a number of years, while the boosters themselves are more tightly year specific and since the masters swap around I assume the difference is in the pedal rod length and pedal bracket differences... I recently went junkyard shopping for a midland booster for a 68 at a vintage mopar yard and I saw a number of boosters in my year range that were ''Bendix style" but looked completely different each other and from anything I'd seen before...maybe at some point there were aftermarket boosters available that fit and worked but didn"t look like the factory ones? There were also Bendix boosters available for the dealers to retrofit power brakes into cars on the lot that had manual brakes...

Yep, OEM dealer upgrade accessory kits for power brakes, back then.
