Re[2]: {Chrysler 300} 300J/K remote brake booster

["Carl Bilter" <cbilter@xxxxxxxxx>]

I was going to mention searching out a truck place, but the problem is Nick doesn't have a booster to be rebuilt.  Maybe a truck place could find one that will work.  Logic might say bigger booster = more vacuum = more boost, but I suspect a number of other parameters affect boost, and I don't have knowledge on that.  The only automobile booster rebuilder we have good reports on for J and ram K boosters is Karps, if one is found.    Worst case, in interim, the car can be driven as a manual brake car with no booster, it's a manual master cylinder on the firewall, and these days they no longer seem to have the check valve, at least on the new mcs I've seen.  

My J still has the original booster, never rebuilt, still has factory undercoating, doesn't leak vacuum (yet), no doubt a problem waiting to happen but so far in 20 years of ownership ok.  Bendix brakes, stops ok, but  57-61 center plane brakes, properly installed and adjusted, will stop better!  At least for me they do.

no one has mentioned it, but millions of these are in use on medium size straight box trucks . You can see them bolted to frame rail under the box . 

I had very poor results with “ expert rebuilders “ on a J . It was put together wrong when dissected third time by a truck place . locked up etc etc . Did not trust  it enough to even drive car for a year . 

So I chased this down , truck places like International Harvester etc do many a year . J is smaller but same design and possibly same parts as a truck unit .

It was 25 years ago , but my 

problem was solved and reasonable cost by a real

 pro truck

mechanic . 

hope this helps

This 1960 Dart Phoenix has the same type of booster under the hood. I'd assume that was a dealer installed brake booster setup.

Hi Nick. For a 63 64 ram booster Murry Park or Jeff Carter are probably going to be your best bet. Bracket can be easily made. Mine is off the car if you need measurements. Greg

I found some 7 inch VH44 ones online. In Australia, they used a 9 inch VH40 one but the back of it is a different shape and the thing that looks like a breather is angled.

I know that A108 vans used a remote booster but not sure of the size. They even used two of them with the dual master cylinder.

Hoping to find an original setup. I do have pictures of the brackets.

I really don't know anything about how these differ. Is a smaller one just less boost or are there other things that would stop me from using one that isn't correct? Australian listings have them for drum or disc and there was also a single booster that was for dual circuit brakes.

Nick,

 

You can probably fabricate the bracket if need be. The booster may be harder to get.  You could use one from a 1950’s T-Bird, it is a remote midland ross unit, although the boost graph may be a little different.

My ram 300K is missing the remote brake booster setup. Anyone have one they don't need? Need all the brackets as well. A previous owner was putting disc brakes on the car and removed it all and it's been through 3 owners before I got it.

 

Other than the ram car torsion bars, that's the last unique part I'm trying to find.

 

Thanks, Nick
