4. 3/4" ratchet or air tool
5. 15/16" deep socket
6. Teflon paste or tape

Just a tip or two from another machanic. You can use the brake adjuster to your advantage, after you pull out the clavis pin use the brake adjuster and open up the brakes. When you feel that the brakes are fully open keep turning a little more and that will pull the arm of the brake adjuster out of your way when you go open the mounting nuts. 2 if you have shop air handy you can skip the spring brake cage bolts, after you disconnect the air lines from the caliber just connect shop air to the spring brake side. And the new spring brake cage bolts you should put those in the cab so they wont rust. We have had many calibers cracked because of those bolts rusting inside that aluminium hole on the calibers side.

Appreciate all the tips. Sounds like you know what you're doing. I don't have an air Compressor. I'm about out of room in my one car garage. I'll have to take off those caging bolts and put them in the cab. That makes sense. And getting the slack adjuster out of the way how you said makes sense too. It got in the way a lot.

Nice video ! I would like to add an item. Pipe threads get the teflon paste, you should never add teflon paste to a metal to metal seal like the seal from the air hose to the fitting you screwed into the brake chamber. Don't put anything on that side of the fitting, just make sure that it is real clean, those threads on that side do not do any sealing it's the metal to metal part at the beginning of the fitting that does the sealing. @ 18:04 If you have an air leak in the future, I would look at this fitting first.I hope this helps you ! Be safe and have a good day!

Oh, ok. Appreciate the tip. I never know when or when not to add the Teflon half the time. So you're saying it needs nothing? Just bare?

@@RNP69 there was one flare connection and three NPT connections. he put pipe dope on all four. the only one that didn't need pipe dope was the flare. NPT connections never seal air tight. you've been putting air leaks back on the road my guy. nobody even uses flare fittings on brake lines anymore. get with the times.

after touching about 3500 dry box van trailers over the past 6 years I've realized that a lot of individuals can't execute this process very well. I've set up close to 200 brake chambers and replaced service diaphragms on another 100. most of the guys I know that work on tractors do what they call back-halfing. they only replace the front part of the chamber, effectively avoiding: removing the clevis, removing the chamber nuts, and measuring/cutting the push-rod. After that process you've replaced all the air-sealing components and replicated the brake stroke from before. do what you will with this info. I always replace the entire chamber, adhering to the entire manufacturer procedure. I hate the pipe goop. I'm a taper. I've sealed over 1000 units to

Sounds like you know what you're doing. Yeah, a lot of guys were saying I don't have to replace the whole thing, but I figure if one part is bad, the other is probably close to going bad. Might as well do it all while I'm down there as well as the other side so everything is even. I hate having a bunch of mismatched parts. What is it about the Teflon paste that you don't like? The stickiness? That stuff is impossible to get off your hands. One guy said there's no reason to put anything on the connections since they're tapered. Idk. I like extra security.

@@aftersolo I was using tape, three wraps, and making sure I went the correct way so it wouldn't peel back when you screwed it in, for a few years. I went to a new company and they said we only use the paste, I used it one time and hated it. I continued using the teflon tape I had in my box. eventually they got me more of it. Earlier in my career I argued with a guy that you didn't need any sealant (tape or dope) and he proved me wrong with a leak-down test on job I had just done. The fittings we stock currently have some pink stuff on the threads already from the factory. I assume it's a thread sealant. I still put two layers of tape. I always liked flare fittings but I haven't come across one in a long time on an air brake system. maybe they're more common on tractors. old dude is right about not needing any sealant on the flare fitting.

@brucemcelroy3186 ok. I appreciate all the input. All I did was drive trucks for 9 years and never really learned anything about them. I've had the business 6 years now, and I've learned so much about working on them. I've always been mechanically inclined growing up on a farm and all, so this truck is kind of like my farm I guess you could say. There's always something to do on it and always something to do with it. Keeps me busy.
