also aren't the biodegradable wiring harnesses more of a late 80s - 90s thing? like W124s and W140s
Yep, that's the channel. Interesting sidenote: his shop is like 3 miles from me, 2 blocks over from my BMW mechanic. And yeah, definitely not as common as the coil packs.

You are right about the biodegradable harnesses, that was 1992-1996. They just decay on their own. But I'm pretty sure (could be wrong) that some of the later ones are "tasty" and critters like to eat them.

Yeah you wouldn't really get better stopping power out of CCBs. Their main advantages on the street are zero dusting, and the fact that the non-abusive environment should lead them to lasting the life of the car.

Where they really come into their own is their performance on repeated hard braking--just like you'd see on a track--due to their ability to handle a massive amount of heat without fading. Unfortunately, this causes them to wear quickly and require replacement. So ironically a lot of folks who track their cars and are not made of money swap their CCBs for steel brakes when going to the track.

I still get what you mean but don't sell your car short, and DON'T go to Jiffy Lube.
Definitely not selling it short, it’s just not the kind of car we’re talking about here. No jiffy lube don’t worry!

oh man i'm jealous... i don't live near any major youtubers with repair shops lol

ideally i'd like to go to him for the E55 and the car care nut for the LS 400, who i'm pretty sure is also in IL

hmm i wonder what could make one wiring harness tastier than another lmao... maybe it's the coolant/oil that leaks down and gives some flavor... either way that sounds like it could be solved by parking inside

My understand as to the "tasty" wiring harness was the use of Soy products in the insulation.

Ok, then that is the biodegradable ones from 1992-1996. My bad on that end.

Not only fading, but ceramic brakes are also resistant to the warping/runout from heat that you get with steel rotors.

Steel rotors don’t warp with heat. What happens is the rotors get hot spots and brake pad material sticks to them and that creates high spots which cause a pulsation in the brake pedal. Good quality steel rotors torqued properly won’t “warp”

Two more of my agents just turned their luxury cars in for Tesla Model 3s. One a 3 Series BMW and the other an E Class Mercedes…

hence why if i have to stop short when pulling up to a red light on a high speed road, i'll gradually ease forward ever so slightly so the pads don't stay in the same spot the whole time... and things have stayed perfectly smooth for years on both my cars

Absolutely, everybody should do that. Lexus rotors are pretty crappy, I have had many sets of warped rotors on Lexus cars until I go to aftermarket rotors, the OEM rotors on the Mercedes are great though.

I think one of the reasons for this change is their luxury brand's new models are not appealing to them while tesla, even 3s, haven't changed but in a way new experience to them. So they made the change. On top of it, they get other benefits along the way. For me instance, I don't have a compelling replacement for mine and teslas are not appealing to me either. So I'm kind of stuck. But that's good too. I can keep my money.

The one I talked to (the 3 Series) has long wanted a Tesla and finally took the leap to EV, haven’t talked to the guy with the E Class yet. He really loved his E Class though

Heat is still one of the main causes of warping, though. This article gives some good details.

https://www.repairsmith.com/blog/warped-rotor/

In general, though, even steel rotors, today, are much better at resisting warpage than those I remember from the 70s and 80s. I owned several vehicles where it was a real and stubborn reoccurring problem, even with moderate brake-use.

Oh yeah, I do this too without really thinking about it.

And yes you can get brakes to last forever, I still don't even need a resurface in my LS430 yet and it was 6 years ago I replaced all the brakes head to toe.
