multiply that price times however many wheel ends you need to do

Seems like the discs are often inboard too…. I thought we were done with that inboard crap 30+ years ago so it takes a wheel seal to
It does appear that on routinely driven trucks/trailers they last more miles but for seasonal stuff the discs seem to rust up and then the downward spiral begins.

again I really don’t have a lot of experience with them so maybe my opinion isn’t the best.

 

Have trailers with 1M+, calipers work fine still. 8-900K on the rotors. Pads, 450-550K

 

That's what I've heard but they very rarely need to be rebuild, or anything else for that matter. My last truck I put 750k on after the first owner put 600k on, one pad change throughout the time I owned the truck. No other brake work ever.

But I don't live or hardly run in rust country. That would make a big difference.

 

Literally only changed on pad because of something odd or you mean the whole set?

 

wichris's trucks run it. Seems like discs are higher upfront costs but they last so long that it's about even cost wise with drums. They're for sure better stopping power and simpler overall. For not having to grease s-cams all the time I'd actually pay a premium for that it's just one less BS job to have to do.

 

My 2014 389 had 700,000 on it when I couldn’t stand the thought of having never feasted my eyes on the wheel bearings (except for the two drivers wheel seals I had to replace) and since $350 didn’t seem like a ton of money at the time, I decided to put all new brake pads on it. The old ones were all of 50%. It was kind of a waste of money. Yes it is easier to do a wheel seal on a drum but these disks are as maintenance free as anything I’ve ever experienced. I will NEVER buy another drum brake unit again!


(Unless I get stupid and buy a fleet)

 

One set, and it was the same as above. They weren't even worn more than halfway down! I had already bought the pads so I went on and changed them.
