For Sale - 1967 and 1968 brake boosters for power drum brakes

Here you go...

Bottom photo is from a very original car that's only had some maintenance related work done under the hood. The top car has had quite a bit of detailing done to the engine bay, but I don't think anything was actually removed from the firewall and fenders. Some things have been repainted and...

Disc brake equipped cars have a Bendix dual diaphragm booster, drum cars have a Bendix single diaphragm booster for '70. The single diaphragm boosters will still stop the car but they have about 25% less braking action. Dave

Thank you. A lot of the information I've gathered so far has been from your write-ups in the forums. Very informative.

Yeah man, my 505/727 setup has the 440 source 505 kit, 10.5:1 CR, a .600 lift Howards Cam in it, Trickflow 240 heads with Hughes Roller Rocker Arms (which are AMAZING by the way), custom pushrods, Cometic Head Gaskets to raise the CR to around 11:1, RPM Performer Intake, shorty truck headers...

Agreed, and my docs are very clear on what are the acceptable boosters, and NOT to reuse the drum booster, and I do make mention of concerns over front brake flex hoses, and include some readily available substitutes from later model vans. I also make sure to note that people should always have...

Let me know what they say, please. I'm going to eventually have the front power drums converted to discs when I hit that particular system. It'll be interesting to know what kind of mods, if any, need to be made to use their 9 inch power brake boosters on our C Bodies.

They were dual diaphragm boosters with the 440 engine, which this is being converted to. Dave

Would you be willing to post a photo of the engine bay? For reasons I outline in this thread, I am especially interested in the master cylinder and the power booster. Thank you in advance!

Will do! I’m expecting to hear back Monday at the earliest so hang on

I believe that's a Bendix booster. I'm pretty sure they were original equipment in 1968. Chrysler used a few different suppliers for boosters, and I think a car coming down the assembly line got whatever they happened to be using that day. Yours does appear to be a reman that's fairly recent...

I did this conversion on my 66 300 before I sold it to Ripinator. 1. 1969 thru 1972 spindles are the same, 1973 bolts in, but they have a larger wheel bearing, and are getting quite hard to find. The rotors, bearings, and grease seal must be the correct ones for the spindle you get. 2. The...

Having reviewed this thread, I too did the 73 disc conversion a few years ago and used the drum booster up until now. my experience is that the drum booster works well if the vacuum is at peak suction when engine is cold. Also good if you can ease into brake application while driving. Quick...

Does you friend have a Bendix dual diaphragm booster or the larger diameter single diaphragm, both of these were used with disc brakes in '71. Also used was the small diameter Bendix single diaphragm booster with drum brakes. None of these will be a stock item at you local parts house. Best...

If this is a drum brake car, the booster will be a Midland-Ross single clamp booster. www.deweyboosterexchange.com usually has cores to supply if they are rebuilding the unit. Single clamp boosters were pretty common, you should be able to find one from a parts car or a vintage yard. Dave

Thanks to @Megawattkid, we can add another datapoint. Build date for his 1970 Polara ‘vert, DL27G0D118871 , was 9/8/1969. Her master cylinder, which I assume is original, looks like the equipment on all cars built till at least Oct. 31 / before the change to the center-screw unit, which took...

Hey all, Regarding 66-68 C body cars - while I know that a Bendix dual diaphragm disc brake booster is supposed to be a semi gloss black (and KH drum boosters are cad plated), what colour is a dual res disc/drum master cylinder supposed to be? Were they painted at all? It's my thoughts that...

Thanks a lot! Build date for DL27G0D118871 was 9/8/1969. Her master cylinder, which I assume is original, looks like the equipment on all cars built till at least Oct. 31 and before at the earliest Nov. 5, 1969. This is really helpful. I am now confident that I can send both the booster and...

Guys, if you need an option for a disc (dual diaphragm) booster my 69 fury uses this Cardone booster 54-73309 from a 75+ fury. Fits fine except the hole in the mounting bracket needs to be widened to fit the rubber cover and because its longer it interferes with a column shifter if you have...
