@hopper1 TRP parts is mostly what we use at our KW dealership and I believe they are part of Paccar or atleast on the KW side. I was just wondering because it looked very similar to the TRP piggys.
@MossyOak83 I have no idea what brand it was. We normally stock whatever is on special. If we run out (frequently do) we'll get spring brakes from the nearest supplier. If the shit really hits the fan we can call one of the other shops in town and bum one or two to finish a service call.
Like your setup with the glad hands. Also was good thing to point out how dangerous it can be around brake chambers (quite a few people have died because of them I was under a truck one day doing a piggy back and my air line blew apart scared the living shit out of me all i heard was ringing in my ears and a couple of the guys yelling are you ok ) and to show people how to use a caging bolt.
@4000xt Sorry for the late reply. The two things that really scare the shit outta me are inflating tires (especially ones that have been run low for too long. Zipper rupture waiting to happen) and spring brakes. I had a caging bolt break on me once as I got the spring about 90% compressed. Just about crapped my pants when that happened.
Where you from anyways?... Ohio here... You seem to be a pretty decent mechanic... The shop that I work at, people are always throwing parts at the problems instead of a proper diagnosis...
Nice video... Had one a few weeks ago, took over from another tech... Symptom "Brakes slow to release"... He put a valve on it and same problem, ended up only being a kinked blue air line from truck to trailer... When we applied the service brake, the line unkinked and went straight, but releasing the service brake, the line kinked and held the majority of the air in the service side...
Great video. Really interesting to see how that's done. There are a few 'bitey' components on planes. The one closest to this would be the huge feathering spring in the prop dome. It can go a LONG way if you undo stuff in the wrong order, and you don't want to be standing in front of it when it decides to depart the aircraft.
Damn that slush you have to work in looks uncomfortable. My last job was in a heated hangar, and I did it in a suit and tie (apart from crawling in the equipment bays). :)
@hopper1 coil, about four inches across, made from about 1/2 inch steel. Fully compressed, it's about 5 inches long, much bigger when it flies across the workshop! That's in a light plane. On something big, I'd hate to think.
Great Video! Glad you stressed the safety and danger of a air can chamber. I remember when I was a little kid my dad was hooking to a old flatbed trailer loaded with oranges in a grove, well old trailer's didnt have duel air can parking/service brakes like in this video. Long story short, flip the front of the trailer over the tractor tandem's but not completely over and a bin of oranges fell and spilled all over the place lol
@BigDan855 I saw that old style of air brake system once. The way air brakes are these days, they're much more safe. Sometimes it sucks when a major leak happens and the brakes automatically apply. Such as in the middle of an intersection.
Nice work and very interesting to an auto mechanic. This air stuff is all greek to me except for the caging of course. Looks like it's still cold there too brrrr Great video!
@GordyMariFilms The way I see it, air brakes are much more safe than hydraulic brakes. If you develop a leak with hydraulic brakes you will be able to stop, but with a severely reduced amount of available braking power. With air brakes, if you develop a leak the brakes automatically apply. It has to be a big enough leak where the compressor can't maintain enough pressure to keep the spring in the spring brake compressed.
Great vid Tim. Always happy to see that style air hoses as they never seize up. Why does it seem that drivers always find the muddy parking spots when this happens?
@johnfz1 Yep, I was happy to see field kits on those hoses. The hoses with the flared metal ends tick me off. I'll try and get them loose once and if they don't budge, I cut the hose and either make a new one or put a field kit on the cut end. It's also a drag when the swivel end is up at the valve and not the chamber.
I love the how to vids you do, I get to see an aspect of trucks I never get to. I never knew trailer brakes were that involved shows how much really goes into these trucks
right on dude, haha this reminds me of when i used to go on service calls. you could also put vise grips on the pushrod when the brakes are dynamited so the service spring stays in place and then just take off the piggyback.
@domepiece604 I used to do that, but backing off the slack adjuster gives me an idea of its condition. I've found quite a few bad slacks and seized cam bushings doing it this way. That, of course, leads to more work and more money. But, if I have to change a spring brake out on the side of a highway, vise grips get used in the interest of speed.
was that a TRP piggy?, I'm gonna have to get me a set of glad hands, although I dont work much on trailers they sure look handy lol.

If you are in the tire changing business you leave the bolts on the ground. I dont know about you but I wish the snow would go the hell away already!
