Those aren't auto slack adjusters. Those are old style slack adjusters. These you must adjust every month or when the brakes aren't stopping enough. Auto slack adjusters are made differently and adjust when you come to a stop and put 30 pounds of pressure on the brake Now some road rambos are already screaming you'll burn up your brakes putting so much pressure on them but if they would actually READ their owners manual or the manafactures manual on the auto adjusters they would learn that the most effecent way is when coming to a stop is let the truck stop as you usually do then release the brakes and roll a few inches then actually push the brakes hard so you put at least 30 pounds of air pressure on the system which activates the adjusting mechanism in the adjusters. Do this 3 or 4 times and you'll notice a big difference in the stopping power. And no you aren't burning up your brakes if you're not generating heat at speed! You're freaking stopped doing a needed adjustment. OR do it at the end of the day when parking the truck. Do it the same way in reverse and forward. NOW some auto adjusters will adjust while parked and the brakes are released. Just apply 30-60 pounds at least 10 times if you dont do this every day. And it's a good way to test your emergency brakes! Note: they will NOT over adjust. So dont worry. If I'm doing a lot of city driving I'll do an adjustment once or twice durring my deliveries to keep them in top stopping adjustment! AND a tip! Get that red light to pull around back at the scales for that oh so fun DOT inspection? Do the above to make sure those brakes are in adjustment before he goes under the truck with his tape measure! But do this on a daily and you're never going to get a write up OR be accused of out of adjustment brakes in case of an accident. Try it today and be amazed! I find it funny that not a single big box company tell their new hires about this process as most if those class room instructors never had to even do a manual adjustment on either style of slack adjuster!

My company has 10,000+ trailers. Every trailer I hook to is for the first and last time. I know a trailer needs adjustment when the brakes are fully applied and 4 loud "thunks" are heard. That's the ratchet mechanisms working. Once that's heard, I'll keep pumping at ~80+ psi until the thunking stops.
Look guys this are automatic slack adjusters. They have been mandatory since 94 for trucks and the year after for trailers. The anchor strap is on top.
Are these Gumite? Most buses at my job are Bendix, and they have the pull pawl that you have to release before taking them in. Also, I go a half a turn back when adjusting them. At least that’s how I was taught.
Just wondering the same thing. Saw these this morning, and so watched this video on them. Didn't see the pawl on mine. Have also heard both 1/4 and 1/2 turn. Have also heard a credit card should fit between shoe and drum.
I now work at the city, doing trash trucks. They don’t have a pull pawl. You just take a 9/16 socket (for most) and turn it in or out. I now do a 1/4 turn because that’s what they do here. Also studying for my ASE right now and it says the rule of thumb is tighten all the way down, 1/4 turn back. Never heard the credit card rule.
The only time you adjust auto slack adjusters is during installation and when testing. In between time you don't touch them. The rule of thumb is a 1/2 turn. Even if you turned it 1 turn the auto slack adjuster will correct it in 20 or so brake pedal pushes. Adjusting too little the adjuster can't correct and then you have brake shoe drag.
@@Uncleshawny , how long have you been driving? Auto slack adjusters do need to be adjusted, so you get under your trailer at a truck stop and adjust them, then get a buddy to press your breaks? ,( during your pre trip) anyways good video
they usually do unless they havent been greased. make sure you have 100lbs of air. push your brake pedal to the floor and hold it there for 5 seconds. release. build air if you need to get back to 100 and repeat.
I like how everyone in the comments thinks they know what they are talking about yet every person is giving a different answer lmao 😂 fucking yuppies man, good video
Technically only qualified mechanic should adjust automatic slack adjusters. Drivers should not adjust them. Manual slack adjusters ok for drivers to adjust but not automatic slack adjusters .
@@TRUCKINGTIPSDIY with an automatic slack adjuster you have to back off the locking mechanism, the way you did it works for a manual slack adjustment but if you havent already you will eventually brake the slack adjuster
@@fstompo That's a haldex slack. They do not have a locking mechanism(pawl) and it is normal for these slacks to be making that sound when you are backing them off. it's a problem when you do not hear that noise.
@@manavsaini3956true I have the same ones and when you don’t hear that noise when backing off then you need a new slack adjuster bc that nut isn’t holding the mechanism down
how to adjust automatic slack adjuster that it’s not automatically adjusting by himself ... ? manually !!! 😝😝😝 😎😎😎 dot should give some violations to the producers of those automatic slack adjuster... right ??? 😬😬😬
If they are not set right after work. Its Drivers falt. It's always been that way. Pass the buck is lazy man's way. So I see you are a very hard worker. Keep working on placing blame you are great at that.
This is incorrect you never tighten a auto slack all the way and back off, should be small amount right check never back it off that clicking noise is wrecking your slack
This must have been a really hard video for you to make because of the tight space where you have to work. Thank you for posting it.
thank you !!!
Thanks for posting this I have to renew my license. I never have to touch anything but I still have to know it lol.
Thanks for posting, this helps.

tell that to a CHP inspector!
Never seen an auto slack adjuster work properly yet. I'll grab the tools and check for proper shoe to drum clearance every couple of weeks.
You're joking right. It's called a pre trip inspection forna reason. If you drive like that turn in your CDL thanks

@@wheresfrankie no I must have commented on the wrong thread on this video. I always adjust mine if needed and even lube them to spec.
Thank you Sir
Thanks for watching sir 🙏
Why would you adjust brakes without the wheels mounted and also why would you trust truck sitting on a jack without a jack stand
its for the viedo only to get better video, im not going to remove the wheels every time i adjust brakes
Hey how come people say they automatically adjust just by pressing brake 6-10 times all the way in while parked? Is this true?
they usually do unless they havent been greased. make sure you have 100lbs of air. push your brake pedal to the floor and hold it there for 5 seconds. release. build air if you need to get back to 100 and repeat.
Do you recommend this at every service or only on wherl end repairs?
Where are the jack stands rule number 1 never go under without stands
Good informational video use the wrench clink the drumb. Tune it like a instrument that called tuning the breaks
but the manual says to just wear glovers and pull on it
I like how everyone in the comments thinks they know what they are talking about yet every person is giving a different answer lmao 😂 fucking yuppies man, good video
Hey, Can you tell me what brand slack adjusters these are?
i will check and let you know
Why didn't you just apply the brakes three times? automatic slack Adjusters Will adjust on their own unless it's sticky or needs some grease.
Technically only qualified mechanic should adjust automatic slack adjusters. Drivers should not adjust them. Manual slack adjusters ok for drivers to adjust but not automatic slack adjusters .
all you have to do is to mount the tires first and torch them and only after your allowed to adjust the brakes... ;)
ASMR
You're damaging the gears that make them automatically adjust when you do it like that
how do you adjust your brakes?

Craig McNeil😃 relax man 😁
@@c.a.mcneil7599 What is falt ?
I could be wrong but to adjust automatic slack adjusters on most if not all you have to be above 90 psi and do 6 bake applications
The producer of this video needs some dot violations. ASA slacks work good. Manual slacks work good as well
