Thinking about replacing all 6 chambers on my t680. I did have one blow out on me about 6 months ago and it ####ing sucks when it happens. Alternatively I could just change the diaphragms in them quickly and cheaply. The truck does have 500k miles on it now though and I'm thinking it's one of those things you might as well do as a PM so you don't have to cage one on the side of the road. Might also be a good idea to change those air lines to each of them while it's off.
Thoughts on if this is just a waste of money because they can last hundreds of thousands more miles or maybe just buy a single one and keep it in the truck?
Brake chamber PM.

The last 30/30 can I bought was less then $40, if that’s the national debt to you replacing cans are probably the least of your worries.

Keep a halfback and diaphragm handy on the truck, if youre going to replace things preventatively, just do all the pancakes (diaphrams).
If the part you arent trusting is the mounting end, yes just replace all of em at one go.lilillill, Bean Jr. and RunningAces Thank this. -

I did all six on my truck this year. Also did s cams, bushings, slack adjusters, drums, shoes, bearings, hubs and caps. The whole deal. How do your s cams and bushings look? Might want to consider doing everything if you can swing the expense.

Not worry too much about steers, but would also change both hoses on each

You can not replace the parking diaphragm. That's the one that usually causes the trouble. Or a broken parking spring.
From my experience, you are quite right. If one goes, the others are not too far.
Getting stranded at the side of the road due to too much air loss and the other chambers apply the brakes can get costly.
I did the rears all at once at some point. A few years later, they all failed again within a year.
I do carry the rear part, a clamp and a diaphragm with me. Just in case.Pamela1990 and RunningAces Thank this.
