I have often been behind large arctics going along the motorway (nothing new there) and I have often wondered what the two circular things that look like they are secured to the axle do/are for, well the other day I was a passenger, and I managed to take the below picture of said objects. Sorry, no prizes.

Above are my opinions Below is my signature.
Would you hit a nail with a shoe because you don't have a hammer? of course not, then why work on anything electrical without a means of testing Click Here to buy a "tester" just because it works, does NOT mean it is safe.
If gloom had a voice, it would be me.

Thanks, well I never. They are the brake operation thingies (new technical word) they have a "piston" that either retracts or extends. Now I know what they are for, I can look to find out what the piston is connected to, and where that is.

You obviously meant an artic as in articulated lorry.
One of those words that are often incorrectly used like Pacific instead of specific.

I was recently chatting to someone on another forum. He has a Zil 131 which for those who don't know is a 6x6 truck used by Russia and eastern bloc countries. He was explaining that the brakes work "backwards" to european and UK vehicles. Over here the air pressure holds the brakes off hence why an artic loses the air lines the trailer brakes are locked on. With the Zil the air forces the brakes on. Better in a military situation because if an air line is damaged perhaps by ambush or IED the truck can still drive it's way out of danger and brake with the gears .
