We it is resolved, some people just won’t accept facts and inconvient truths. Oddly enough as the drum brake gets older its being used in higher tech vehicles more and more. That is not because it is antiquated or substandard technology. Quite the contrary
Well certainly thinner than water 0w20 or 0w18 isn’t the answer. This has been proven by GM and the 6.2
They finally said “stop the madness and get that thin oil out of there and run some 5w30”

Nonsense. Millions of cars use those with no problem whatsoever. One engine design has problems? I blame the design, not the oil.

Well no ■■■■ Sherlock…
You do realize that the front disc and rear drum brakes have been common place on vehicles since the late 60’s and basically standard place in the 70’s, so of course your 2005 is not a new thing…And EVERY regular member knows and understands this…

Yes, but they are NOT making a come back on regular ICE vehicles, they are ONLY being used in automotive vehicles that barely even use the rear brakes, so it doesn’t matter that rear drums or disc brakes are being used… With regenerative braking, the use of rear brakes, although still required and needed, are hardly used… If a regular ICE vehicle is only using on average about 20-30% of the rear disc or drum brakes, then you add regen braking to the mix where it uses around 70% of the motors to stop the vehicle, that leaves 30% use of the brakes, so now the brakes are only being used 30% of the time when braking, then you take 30% of that and the rear brakes are only being used something like 0.09% of the time under normal braking, lets just move that way up to even 10% the rear brakes are even being applied, so you don’t need anything more than a basic rear drum brake in a vehicle with regenerative braking eg. Hybrid and or EV’s…
It is not hard to understand…

My Tesla Model 3 has disk brakes on all 4 wheels. Regenerative braking is done with the electric motor.
The same is true with my 450h+.
Then why not have no rear bakes at all?
The fact that the rears do so little braking has nothing directly to do with why top manufacturers are putting drums on the rear. It has to do with the durability of drums. Disc brakes are fragile, one night in the rain, especially with these ridiculous open spoke rims we have now, one night and the discs start rusting themselves to pieces.
Drums are much less prone to lot rot.
If sizes are equal, drum brakes are just as powerful as discs. Heavy haul trucks still use drum brakes. Very powerful brakes. I admit they do fade but a professional driver doesn’t hit the brake pedal like they are playing a pump organ.
They also have a small RPM operating range of what 2500 rpms (idle to redline) and can use the gearing to slow Semis down…
Comparing Semis to cars and light trucks is like comparing apples to crackers…
I suppose cars should start running straight front axle beams on the front also cause they work great in semis/dump trucks, I guess cars should also start running air brakes cause they work great on semis also???
How about we go to leaf springs on the front of cars and light trucks since they are so powerful on semis???
I can see it now, the all new Corolla with state of the art front leaf spring solid straight front axle with rear air bags and air brake drum brakes all around… Sounds awesome!!!

You don’t read what you post. It has everything to do with how little braking is done by rear axles when front discs AND regenerative braking is present, on small hybrids and EVs.
its not just us that disagree with you, the entire automotive industry does. If a company could gain a competitive advantage by employing the “superior” drum brakes all around, they would in a second. NONE have done that.

When reading the repetitive opinions of a couple of forum members who keep posting the same stuff… again, and again, and again… a quotation from JFK comes to mind:
If only they can post the same stuff a few thousand more times, then they can convince everyone else… or so they think.

@ChrisTheTireWhisperer and @Old-Days-Rick may believe they “won” because they . . . or someone else . . . got my comment removed
But that doesn’t mean it didn’t happen
I still stand by what I said
here goes . . .
several years ago, you @Old-Days-Rick said you finally had to admit that having drum brakes all around were NOT the best thing since sliced bread
In fact, you said they FAILED you disastrously
You said you were driving your vehicle with drums front and rear and applied the brakes, only to have them all massively fade
You plowed straight through the stop light, red light, etc. and wound up in the middle of a 4way intersection, lucky to have not slammed into anyone else
And it was under one of your previous usernames . . .
you can change your names, but we remember

I don’t care as much about his obsession over drum brakes in general, as I do him comparing Semi trucks (includes Dump trucks) and what they use brake wise to light duty vehicles…
You can in no useful way compare a semi braking ability to a Camry etc… Most gas engine have a redline around 6000 rpms, so down shifting at 1800 rpms will bring you up to like 2500 rpms depending, well the vehicle can still run up to 6000 rpms, that is why we use our brakes, a semi at the same 1800 rpms down shifts and it will be about out of rpms, so can’t go any faster…
Semis are built to downshift while stopping, automatics are not, even though they have engine braking, I am not gonna tear my transmission up or damage my engine by downshifting instead of using my brakes, pads and rotors are wayyyy cheaper than an engine or transmission… And the last time I checked, my cars and trucks don’t have Jake brakes…

If we’re really going to return to his yearned-for Good Old Days, then I guess that having mechanical (rather than hydraulic) drum brakes would make a certain person happy.
If we were to go back a bit further (pre 1930s), most cars had (mechanical) brakes on only the rear wheels. Now that was true perfection!

I had nothing to do with a comment getting removed.
Years ago I was doing a test on a vehicle and it was a friends. Yes I was able to get the drum brakes to fade spectacularly.
I drive a vehicle with all drum brakes most days, hauling alot of weightand have never had an issue. The issue is had with that old power wagon was more indicative of the times than a problem with drum brakes.
I changed my screen name because I could not longer access the email or passwords for my old account or old email after I broke my computer. Yes I could say that my old computer just died but ill be honest, I had a problem with it and decided to break it into many pieces.
There is nothing wrong with this and I stand by my actions.
I like you DB, I find your perspective and life experiences valuable as I do many others on here. There is alot of knowledge here collectively and individually!
Dave Mason wrote a song about this very thing and it still rings true over 50 years later.
So, you really do want to go back to mechanical drum brakes, preferably on only the rear wheels?
