Trucker Air Brake Purge

[RavFJR]

Can anyone tell me why some truckers purposely purge their air brakes when I pass them (on the bike, of course)? :huh:

Rav.....It is probably the air brake drier that blows off every so often to free the system of moisture. I used to run big snowplows and until they came out with this system our brakes would freeze a lot.

If you say so... It just seems very coincidental that the same truckers I pass on my work commute nail me when I pass them. <_<

I tend to agree with Scubatech..... Best is not stay beside them for very long. Or stop running with the big trucks! :lol:

Other than a little noise, does it hurt you or cause you some type of harm? Since it doesn't, who cares?

That's a new one. Do you have an effect on street lights?

I don't know of any truck system that has a manual blow switch or button in the cab. Most of them are automatic.

That's the way it's been on the trucks I have driven.

Maybe it's just magnetic personality or a good reason not to be in So. cal.

Yup, just the excess air being purged. The system builds air while the truck is running and a governor releases excess air (above 120psi) so the pressure doesn't build too much. The only way to deliberately release air is to hit the brakes.

Trucking pays my bills and buys me farkles.

Thanks for all the posts... I'll chalk it up to synchronicity.

HotRodZilla: It doesn't hurt... My question was a matter of curiosity, that's all.

Denver_FJR: Nope, the stoplight thing isn't a factor. Sleep well, my friend.

The only other way to get that noise would be to pull the air valve and lock the rears, which is fun when no ones around and your pulling in to the shop!!

Dude - you need to start drinking more heavily and relax.

If you're wearing a utilikilt while riding, they may be trying to see up your skirt.

I don't like to be farted on by people, elephants, or trucks...that being said, I'd rather have a little compressed air blown on me than have a compressed brain from a truck running over me.

Or a multi-hundred pound road gater come flying off it at balistic speeds.

Yes so true.... I never ride along side them.

Agreed! Stay away from us if you can. If you can't, get by us as quickly and as safely as possible. Gators (tire treads), rocks, wood, etc can be thrown without us even knowing about it. Not to mention all the blind spots around most rigs.

Amen to that... Had a couple of 'gators' fly past my head. Last year got a rock thrown at my right knee...took me out for three days. So I guess I've got my answer to the air brake purging...it just does it. Thanks to all for the replies!

Done!
