thanks for helpful vid. hey, just to clarify for future viewers, 1 full turn is 360 degrees; 1/2 turn is 180; 1/4 turn is 90. So after tightening the adjuster, we back it off 1/4 turn.

You forgot to mention one important step. The brakes need to be released when you are adjusting the slack adjuster.

Thank you!!! I'm studying for my CDL and did not understand what the manual was stating. Watching this video made a light in my head go off! 👏

1. Chock the wheels 2. Disable parking brake otherwise you will not be able to pull hard on them to check if they need adjustment 3. Use Gloves and then continue with all instructions given by the expert on this channel.

First step ever is to chock those wheels; Great explaining though definitely subscribed!

Thanks for a refresh. Appreciate the video.

3 clicks or quarter turn is what I do been a mechanic for 30 years half a turn is too much slack is think.

The best video on KZfaq-thanks for posting

Awesome Video!🎥

Good job bro. Thank you I learnt something from you.

Thank u so much!

Brakes released before adjustment and it’s important to be sure the slack adjuster is greased and operating freely , and I’d go over brake chambers I seen a guy pull the death bolt once and if I’d not caught him he’d be hurt bad I like you content good mechanic sir you are

Thank you. This is way better than the State book

Very helpful.. thank you..

Good video short and to the point

1/4on used and 1/2 new. And you forgot to tell people the brakes have to be released.

I always did a quarter turn

1/2 turn is 180

Boy this guy is a genius

THANKS!

You need to measure the stroke after adjustment because dot doesnt play

Good job!

thanks !

Great video

A quarter turn will do if u want them set up tight but tap on drum and make sure they arent touching

Than you so easy.

Make sure the cotter pin is still there. It wont selfadjust without it. That will also cause uneven breaking

Great damn video… thanks for

Thanks From H-town..

Thank u

You need to return it 1/4 turn.

Why are stripping the ratchet mechanism? Use the release pin to back it off. A 1/4 turn not half.

Can you visually tell if your truck has automatic or manual slack adjusters? If so how?

I noticed when I give 1/4 of a turn brakes fade too quick and so it’s when I give 1/2 a turn that is why I give it 135 degrees

Full 90 degrees for half turn 😂 last I checked it was 180 degrees for half turns

That is a Great Video On How To Adjust Your Brakes But The Older Ones are 9/16 and you Have to Push the Lock Collar in so you can turn the bolt ! Good Video ! it Should Be On all The CDL Test So Every One Knows How to adjust there Brakes Just Sayin

My trailer when I hit the brakes hard, rear axle jumps but when I slowly brake and not hit my brakes hard, it doesn't like to dance. Do you know what is the cause of this? I am putting new shocks because they are all bad and new brake chambers.

Could you message me with more info on adjusting I’m about to take my class 3 road test and just want to make sure I got everything locked down!

Thanks!

Did you release the brakes, and have at least 90psi

I've got an issue right now with the front set of tandems on the trailer locking down whenever I'm coming to a stop so I think they are too tight, all I need to do is turn it about a quarter of a turn counterclockwise?

Your suppose to have full tank of air and release parking brake make sure tires are blocked before those drums look gone

1/4 is the way yo go

Thanks

Is half turn equal to180 degree? You mean two quarters? I'm not native speaker so I didn't get it.

Love all the you tube keyboard mechanics on here. Pshhhhh

J - Tech... You in Jacksonville man?

On drive tires do you release brakes or leave them set

Gente: Primero un cepillazo de acero a esas partes y a grabar el video para que quede mas Mechanic.

You will have to teach what a half turn really is.

1/4 it’s better...

I didn’t see a place to wrench an 11 millimeter. It only had a square sided bolt on top

Unless you have replaced the shoes you never ever adjust automatic slack adjusters... If your throw is out past 2 inches for short stroke and 3 inch for long stroke the slack is bad and needs to be replaced...

Good

All my trucking life I did 1/4 turn and hit the drum just to hear that there were not hitting the drum.

do you take brakes off or leave it on

You need to also state a good brake system will never have to be touched after rebuilding a brake system.Also everytime you manually adjust the slack adjuster you are wearing the lock out.That is why A BRAKE THROW CHECK SHOULD BE THE ONLY CHECK DONE, THEN THE SLACK ADJUSTER SHOULD BE DONE IF THE THROW IS OUT OF SPEC.Lastly IF ANYTHING IS OUT the slack adjuster, s cam and chamber should be inspected for wear or damage.

Currently sitting in a snowplow at work learning

One reason you might want to do this is to prevent a wheel fire that turns into a trailer fire, am I right?

Done it as you said. Called for mechanic.

Dose it have to make that noise when Yu losen the slack ?

What size socket is needed to adjust slack adjuster

dirty mechanic clean ur job and give a good presentation

You only adjust the manual slack adjusters

1/2 turn is a little too much. At 1/2 turn the brake is already at 2” stroke. Try 1/4 turn or 7 clicks and the clevice pin is free and you’re at a perfect 1-1/4 - 1-3/8 stroke every time.

Whem adjusting.. Dont brakes need to be released

in our workshop vehicle come we change all brake chamber relay valve and handbrake valve brake drum and s cam shaft brake lining but his parking brake did not worked wh

But best way is to have the wheel in air and have somebody try to spin it before you start to return, and as soon as it starts spinning and you leave it there. It might even less than 1/4 turn and you will have brakes that great.

What’s the wrench size?

My trailer binding

You forgot got to mention to make sure the emergency brake is off . before you start ajusted.

Can’t you find a cleaner unit? To work on

Why is there spider webs on the drums?

180 degrees.

Sometimes it’s ok when the differential leaks a little 😀🇨🇦

It’s actually vehicles after 1994 that has automatic adjusters

Think most people would do just 1/4 turn . I usually do 1/2 turn on the steering axle. 1/4 on every other axle. But 🤷‍♂️

FUCK YEAH !!! TRUCKS !!!

You got follow D.O.T regulation check slack adjuster comfort law regulation no how u like

Is that a wig my son?

360° 180° 90°

First of all chock the wheels and release your brakes! grease all the fittings before you do anything . Then on ALL manual slack adjusters theres a collar to prevent the nut on the slack adjuster from backing you have to knock the durt off of it and you must use a box end wrench, to loose that up I use a hammer on the 🔧, dont beat on it hard! The reason you release your brakes is so you can watch the rod in your brake drum go in while you adjust! Not out! Then when you adjust your slack adjuster all the way up and back off one 1/4! Then test the travel of your slack adjuster on each wheel by either using the proper brake buddy or I have used a large crecent wrench! That travel should be no more than 1/2 an inch and us exactly what a cvse officer is doing under is measuring that travel, he uses you to press the brake but you are usually aline so use a wrench for thd travel! Do this for all wheels and you will guaranteed have fully functioning brakes

** After 1994 all vehicles have automatic Slack Adjuster **

Man your breaks aren’t released and that is an automatic slack adjuster you aren’t supposed to mess with that unless you putting on new break shoes and that’s only to back the breaks off. You step on the breaks multiple times for them to adjust themselves, if the breaks to adjust back to normal operating specs then you replace the slack adjuster because the original is bad.

Man save you a bunch of time and get you a slack adjuster wrench

I run 1/4 turn

I know how to produce truck brake slack adjuster

Thats adjusting brake pads

Could have took brake cleaner to all that grease

180°

90° is a quarter turn...180° is a half turn..jus sayin.

Old man says 1/4 to a 1/2 I’d say it’s in the relm

Sorry Einstein but a half a turn is 180 degrees, 90 degrees is a quarter turn. Don't know what school you went to but you might want to re-enlist and learn your numbers since viewers like me will not take directions from anybody who does not know 360 degrees is a full revolution. DUH!.

Shit man... I must have done something wrong... the brakes started smoking and caught the wheel bearings on fire...WTF? Smoke Show!

180 degrees

I think it’s 1994

If you have to measure the "brake throw", then you should SHOW THAT TOO!! Incomplete again!

You're getting a ticket

ACK-shully practice and ACK-shully breathe and ACK-shully slow down .. then ACK-shully make the ACK-shul video??? as opposed to NOT ACK-shully doing it well

yeah. that is tottaly wrong
