What do you do in situations where the abs light just stays on? And is not giving a blink code, but just remains on

Brilliant! Thank you. I now know what the mechanic was talking about.

This was an incredible video; very informative and helpful. Great job!

Good video man. I work on school buses and we constantly go thru brakes, slack adjusters and S-cams. Good info. I like how you mentioned to use a tool to check the play on the S-cam. We take apart the brake and do the check on the S-cam inside the brake assembly. I never thought to do it on the slack adjuster end. Instead of taking the brake assembly apart you just take off the slack adjuster after you do your travel and adjustment test. Thanks. I'll pass the info to my shop mates. Thanks.

Normal brake application would only be 20 to 30 psi, any more than that psi would be a panic stop.Professonal drivers doing Normal downshifting, would very rarely apply more than 30 psi.

Absolutely phenomenal video man.

I have a damaged valve but am stuck in a small town. Is there a way to bypass the system to get it going to the next town for the correct replacement part?

Thanks for sharing! Good information to know

Nice

Excelent vídeo, fast, detailed and very very useful, thank sir.

Is this dangerous to drive

Sorry to be a pain but would you have a part number by any chance?

Need to do a load test to be sure it can handle the load

Thank you for this video. I knew I had a brake issue, but thought with adjustments it could be solved. After watching this, I see now it needs to be replaced. I’ll stop wasting my time messing with it and put my efforts towards replacing it. Thanks again.

You’re an incredible mechanic!! Thanks for ur advice!! Cheers 🍻

Just the info I needed . 👍🏼

While back I had the same problem when my team driver was on duty, he didn’t pay attention to the warning service light and the pressure built up in the axle then blew the cap window, drained the oil, Efed up the bearing, and I had to reweld the damaged spindle end and changed everything else involved. Now, on the other axle, I can hear a strong leaking sound from the system, and I know for sure there is a little bit of bubbling in the oil that I can see from the hub cap window, so I’m guessing it’s the same problem. Thanks to your video, I can better service the issue, but I thought you would check the connection of the supply line in the new hub for leaks before you bolt it back on. Thanks again, great upload. 👍

Love your videos. Everything is explained in simplest way.

A great video! Thanks for the detail!

Thanks for this instruction video. I was able to purchase a kit. My concern is my liners have a texture surface do you think it will still work? Thanks

Yes the red line supplies the relay valve…. Unless a little bug makes his home in the emergency gladhand. Seen this too many times

I have a question that is completely off topic but i think you might know the answer to. How many brake applications are needed to test reservoir capacity? . I have asked the guys that i work with and they had no idea cant find anything online . it was question on my test, any help is appreciated-Thanks

Awesome tech tip videos you have going. Keep uploading would ya?

Could there have bn a possibility it could have been SV2?

Waw thank you so much real explanation keep posting useful videos like this

Make a video for the tractor protection valve?

Dude keep em coming. The air brake system videos are priceless. I’m studying a lot right now and I understand the operation of most of everything but when reading in a book it’s hard to retain the information. Your videos help a lot.

Very informative and well presented. I was told my Prevost slack adjusters are at the limit. Might be a job I will be doing soon. Subscribed.

Thank you

Thanks for the explanation of what that little thing does. For a $25 part when they go bad it's a big PITA. I might keep a spare one of these in my rig now just cause this is the second time I've had trouble with one.

Straight to the point and great explanation of how the system works, greatly appreciate the video sir !

Wry informative thank you for taking the time to record this video and share it 👍🫡

It’s usually the pressure protection valve!

What if you only seem to develop an axle leak after driving for a while? Being the morning when i air the system up it never leaks but after running for a little bit i can hear it when i do a walk around.

What is remote your holding never seen one

Definitely saving this video for future reference. I ran into this same situation last week, although I didn't know what the value did or was called. I removed the valve and substituted a simple fitting temporarily to verify the problem, then installed a new valve. Thanks.

Where’s part 2? Air accessories and other .

Best and knowledgeable explanation. Thanks.

This vídeo is very useful for me. Thanks for share.

Nice Work, Thank you Is there a bypass tool when one air bag will not pull one set of pins but the other one works, seems like the bad one is not getting air to it, flat.

I have a very similar problem except mine leaks out of the backside of the prm body when the trailer brakes are not set. Supply valve closed, brakes disengaged and leaking out the backside of the prm

Best explained system diagram You explain so well thank you

Will the ppv cause the brakes to not engage when pressing the brake pedal am having trouble with a flatbed not wanting to break when am pushing the pedal their is a delay

Thank you for sharing your knowledge. Good job.
