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.

Yes and trailer has to be hooked up to the truck can’t do it standing alone

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.

Thanks for a refresh. Appreciate the video.

The best video on KZread-thanks for posting

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

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

Thank you. This is way better than the State book

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.

@@apacheone3643 i agree about them being too old, but there are still a lot out there with manual slack adjusters. Tbh, they are not bad as long as they are adjusted right. The adjusting them is a pain and that is why a lot of drivers didn't do it and started crashing, so they came up with auto slack adjusters, which are really not any more safe than regularly adjusted manual slack adjusters, but less hassle and since drivers weren't adjusting the manual adjusters they seemed safer. The problem now is that too many drivers take auto slack adjusters for granted and do not really check them so when they eventually fail, driver either crash or hopefully get put out of service before they crash. Disk brakes are definitely the best if all 3, but come with the problem of either being difficult/nearly impossible to check, on a daily basis, or take a full class to figure out how to check them.

I have had a rebuilder screw up 6 sets of Calipers I video tape a brand new out of the box Caliper and sent it to the rebuilder.

That is why a lot of guys choose to run without them or not get them in the first place.

Done it as you said. Called for mechanic.

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.

It's going to depend on the type of slack adjuster. One like shown in the video must make that noise

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.
