Oooookay, how am I supposed to inspect Disc Brakes?

Ive been inspected several times with my truck 13KW T660 w/all disc brakes and was noted in inspection DISC. Inspector crawled out from underneath truck/trailer and said "your brakes look good" I guess he might've had Xray vision.

 

The standard is whether or not there's rust on the friction surface. Rust = not working.

 

I have a 2014 Cascadia with disc brakes. Changed the front at 600K, rears at 650K with no disc damage. They were worn to minimums. I now plan to replace all at 500K. Depends mostly on your driving, I could have done better.

 

I started reading this thread and was thinking WTH?
This is all confusing as the posts seemed old

Then I seen it started in 2013

 

Once a year at the FMCSA safety inspection or whenever a wheel comes off to repair or replace a tire should be keeping close enough tabs on them i’d guess.

 

Where can this be done?

 

He believes it because it's true. I replaced all my pads at 750k and the old ones had half life at least. I just did it because I'd already bought them and I wanted to see if there would be any improvement. There wasn't.

Truck discs last forever, and require no maintenance.

I know there are skeptics out there but they also say some day we'll be driving electric cars.

I am a school bus driver and just got a bus with air disc breaks as I am about to recertify in 2 days. I have no clue what to do about pre-tripping my air disc breaks! Wish they came with a pre-trip manual.

 

I drive a 2019 cascadia, hauling gas locally.
We generally get about 300k from a set of brakes, though one truck goes through a set a year. That said, i know that driver doesn’t use a Jake, and is brutal on the truck.
I inspect mine from the back, looking for a raised ridge at the lip of the disc, and checking pad thickness best i can.
It’s not exactly perfect, but it works. on my walk around, i look for grinding on the disc, indicating a missing or spent pad.
