You can do it without pulling it but, it’s aggravating and this way you can pull the little piece of pipe off as I’ve had them in some cases where the pipe itself is partially obstructed as well in rare cases.
You can only replace them on the service side (end that the rod exits), the other side are made non-removable due to the extreme pressure the spring is under. If you remove those it can kill you.
Not the safest way no, I admit I should’ve caged it for an informational style video like this. But, I endured the air was built all the way up prior and verified I had no major leaks as somewhat of a “safe guard” against the brakes applying..still not the best way I agree.
wow, i just spent $189 on a new chamber from the dealer. I’m gonna have to do this trick to change that diaphragm (chamber pancake). You made it easy, thanks 😎
He just "air caged" it. Thats why did didn't release the trailer spring brakes. Pretty common practice, but that air line ever came loose, or something cause the system to lose air suddenly, that push rod would come shooting forward like a gun shot. Very unlikely, but I wouldn't risk it.
Thank you. I accidentally clicked on you video and you actually answered the question I’ve been searching the last 3 hours for..what size the nut was for mounting! My bottom 2 came off for some reason and I need to replace them and I sure didn’t want to remove the last one just to find the right size. Thanks a bunch
If it’s leaking on the service side (with pedal depressed or your trolly valve pulled) then clamp off the brake chamber rod like I did with the parking brake applied. Then when you unbolt the clamshell on the service side (DO NOT TOUCH the emergency/park brake side) you won’t have to fight the small spring on the service side going back together.
It happened to me.I'm glad it was now,this video is only two weeks ago.Theres not many videos about this truck on RU-vid.I would like to know what state are you from?not many good mechanics neither lol
I just finished the job.In my version of it didn't put apart ac hoses.When it was unscrewed pull the box then introduced my hand and touched the drain and started draining water and dirt.I drive on the East coast all the time if there's any way I can get your contact in case my truck break down I'll appreciate it.Thank you for the video.
You should try to keep it in, it’s to give you access to install the caging bolt to cage the brake chamber and it also helps keep the dust/debris/water, etc out.
