How Many Miles on Trailer Disc Brakes Do You Get

There was in my operation. I got close to half
a million miles on the tractor brakes. I decided to change them early instead of trying to get more life out of them.

 

I don’t know about the trailer specifically but on my last truck we did the pads at about 500k miles just because I was doing drive tires and have everything off the back anyway. And there was plenty left, I could’ve ran them and sold the truck at 600k like I did and left them for the next guy.

 

I'm not saying you're wrong, it's your truck and money but, any mechanic/dealer I've talked as well as articles I've read online definitely do not recommend 250k miles.

Personally think throwing new rotors on then it's just lightning money on fire... Maybe a full inspection of them at 250k miles but if everything is good and the pads still have tons of meat why blow money?

Definitely not bashing you just sharing my opinion.

3 or 4 of us on here have had the pads changed at nearly the same 500k interval and looks like everyone has had the same results " they could have went longer"...

@Siinman when ya do decide to swap them out will you be doing them or having a shop do the job? Youtube has some really good videos on guys changing them out, looks really simple. To me looked like the hardest part was getting the wheels off LOL.

I'm definitely not a mechanic but would feel comfortable changing them myself...

 

Oh i get it. Most people arent nearly as parinoid as i am. Most of my parinoia comes from imo justifibly my wonderful scrap pile of a truck. Plus most arent at 80k 99% of the time with a jake so bad its usually safer and easier to use my brakes either.

So i tend to chew up equipment at a rather alarming rate and as a result just tend to swap out parts a little earlier then many. Like i said when i ran discs on my trailer 150k had them pretty close to 1/8th of an inch just due to how crap a lot of my equipment is. Though the new jake helps a lot in that it actully will slow the truck down noticeably. But that got installed after i moved to a drum brake trailer.

/shrug tldr im parinoid AF and dont trust my equipment lol.

 

There's nothing worse than a weak jake. I've said it before but the jakes on these new Detroit engines are awesome. At 80,000 lbs I can set my cruise @ 45 mph going down monteagle mountain with the jake on and never touch the brakes all the way to the bottom. Admittedly Monteagle is a hill in comparison to many grades out west but still.

Theoretically that should lead to very minimal use of the disc brakes that the truck is equipped with. And in fact I don't use them that much, not even for redlights. But the ridiculous downshifting from the wonky programming of the AMT is such that you can't use the jake just to slightly bleed down speed because it automatically slams into a lower gear dropping way too much speed than you wanted. So I end up using the brakes a lot more than is necessary. Still wouldn't trade it for manual.
