My old air dryer turned out to be a Bendix AD-1. There is not even a cartridge in it. Since it looks like deals are available on new dryers, I do not think it is worth spending time and effort on this one. Is anyone familiar with the CR Brakemaster model 62? It apparently does not need a cartridge since it works by evaparation. Any known problems with this system? | ||

Uhhh that sounds like problems waiting to happen Lin... To be fair, I know nothing about Brakemaster Dryers, but I believe that of all the hundreds and hundreds of air dryers I have seen over the years Bendix was the manufacturer of probably 99 percent of them with Midland making most of the rest. Sorry your dryer turned out to be an AD-1... The AD-2 it a really good dryer... the AD-4 is a little better the AD-9 a little better than that Any of those are readily available rebuilt and inexpensive to replace components and rebuild. | ||

Lin, I was curious so I checked out the AD-1 online, it almost exactly resembles and AD-2... I don't know who told you otherwise but the dessicant cartridge for both look nearly identical to me... If I were you I would call Bendix directly, believe me they would be HAPPY to help you, and ask first if they still have parts to service the AD-1 and if it would be possible to rebuild the AD-1 with AD-2 parts...

Brian, I believe it is possible to rebuild it, but I don't think it is cost or time effective. Since I do not have a cartridge and the center rod & spring are missing, I figure there's about $60. right there. The heater may or may not work. The same for the purge valve. There is also some sort of check valve in the upper sealed portion that is another unknown. It's about 37 years old and both inlet and outlet ports have been open for who knows how many years. I'm going to watch for one on ebay or something. The CR Brakemaster 62 uses a condensor system and is pretty low maintenance according to some literature. They also make a more heavy duty one that uses a spin-off cartridge. They look good in pictures, but some history would be a better gauge. | ||

It is probably a wise course of action that you replace the entire unit, considering your situation, but if I were you I'd replace it with a rebuilt AD-2. Actually... I might still attempt to scrounge AD-2 parts for your AD-1 to rebuild it and at least see how much it would cost... Because even if ports were left open for all this time, a good long soaking in a bucket of diesel would probably remove almost any crud that migrated inside... I can't give you any history on the Brakemaster dryer, but since their heavy duty unit has a dessicant catridge and every single other air dryer I've ever seen has a dessicant cartridge... I'd have a little trouble believing that a dryer without one would adequately protect my brake system. You might find someone who has some experience with the Brakemaster, but I'd bet none of the diesel mechanics I know, do. Brian | ||

Napa has everthing you need to rebuild it. i just went through my ad 2 this weekend. my heater was ok but they have it too! Purge valve $10.95, Cartridge was $27.95, and they had the check valve too! Like the others have said bendix is in 99% of everything. That is all we have on all our Dot snow plows. Never have any problems with them. | ||

Pre-dryer for longer life. In the commercial diving industry, we used to use a s/s container filled with MARBLES! The air was forced into the middle of the container and into the marbles. A dividing sreen forced the air thru the marble and out the top. Excess condensation was either manually drained out the bottom or via a solenoid actuated valve. by doing this it makes the rest of the system last longer with a lot less maintenance, thus saving money. I've made many variations on this over the years as a pre-dryer and they have all worked fine. Secret is to use glass, as moisture condenses on glass easily, and it also removes a remarkable amount of unwanted oils too. A pipe with coke bottles stacked inside, upside down works well too. route the air in the side and out the top, bleed condensation from the bottom. |
