3rd Gen Concerns

Good analysis. I like the 16 because it's got a hand brake for the rear emergency brake. I use the hand brake in my car when going down short hills in a low gear, like when leaving my apartment building.

 

There must be an alternate Universe in your head..... with alternate laws of physics...
The rest of the world knows Disc brakes are better....., heck even truck company lobbyist know that, but they don't like cost....
Here is very good article from Trucking info on why we are stuck with Drums on Semis (BTW only on rear axles because front axles now sport Disc brakes)

http://www.truckinginfo.com/article/story/2014/07/brake-trends-drums-vs-discs.aspx

BTW ... Aren't we all CDL holders ?
Bottom line you have no clue what you talkign about.
The rest of the world move on from drums, its time to let it go...

 

It is important to remember we are talking about these brakes in reference to a Tacoma, not mega semis or tractors. Also it is really important to remember that in the Tacoma the drums are only in the rear.
This article talks about drum breaks and disc breaks as a whole, and doesn't really differentiate between front and rear use. The overwhelming majority of your stopping power is in the front brakes. The drums aren't going to take up that substantial of a load and these are midsized trucks. They aren't hauling 30K lbs down the road. So over heating, cracking, and wearing down faster and producing a greater cost and replacement burden is irrelevant to the Tacoma drum vs disc debate. Drums probably will last longer in the Tacoma than discs AND they offer much better parking brakes which is important for manual and off road drivers.

There are many highly political decisions made in the US when it comes to a lot of things, but I can't really see why there would be some political scandal to support drum brakes over discs if discs are truly the better and cheaper technology. Not following that frame of logic.

I still think there are bigger fish to fry with the 3rd gens.


Power seats. Power seats. Power seats.

 

does the 2015 4Runner have rear drums ?

 

The 4Runner hasn't used rear drums since 02

 

This place is a cornucopia of logical fallacies. Sweet baby Jesus on a robot T-rex make the bad men stop.

 

I replayed to @archerm3 who posted about Semis using drums because they are better. Drums are not better than Discs, never where and never will. I posted HT article which explains why semis in US are still using drums it was easier than trying to explain... Nothing to do with "better"
Its all about cost. Its not political scandal, simply truck lobbyist don't want new laws passed that would force all trucks to go to disc brakes because they are cheap asss.

Whole conversation about Tacoma not needing discs at the rear is silly. Yes it does, it should have discs back in 2005.

I could explain but I am too lazy, plus everybody whine about my English most of the time so I am just goign to put another link with explanation....

From the linked article:
" 90% of heavy truck buyers today still choose tried-and-true drum brakes, according to manufacturers we talked with. These are not good ol’ drum brakes, but improved designs that stop better and last longer than past products. They have to perform better to meet Federal Motor Vehicle Safety Standard 121’s shorter limits, and to do so many of them are larger. That, in turn, allows their linings to stay in service for more miles, supplier reps say.

"Air disc brakes might some day account for 25% of sales, says Ganaway. More bullish is Randy Petresh, vice president, technical services, at Haldex Commercial Vehicle Systems, which sells a variety of components for brakes and air systems. He thinks disc brake usage might go to 70% in 10 years. Even so, “There’s never going to be a complete conversion. There’s always going to be segments that will stick to drums no matter what. And cost — drums have been in production for 30, 40 years and tooling has been amortized, so drum-brake parts are dirt cheap.”

Seems the trend is not quite what you portrayed it to be.

By the way, not all have CDL. Have not had one since I retired. My wife never had a CDL. To ask your question of "Aren't we all CDL holders ?, is either sarcastic or you just showed your ignorance of the majority of drivers on the road.

 

I want drum brakes in the front.

 

no need for them

 

Ahh, good ol' BlueT and his infinite wisdom. 3gen wouldn't be the same without him.

 

What trend are you talking about, unless you think people are changing to drums ?

Aren't we all have CDL was sarcasm since i hold CDL too.

 

Drum brakes get better MPG

 

Commercial drivers license on google:

Seems like what we call in Canada a class 1 license.

 

My VIN starts with a 5, so that means my DCSB Prerunner V-6 was built in USA!

 

I am in US.

I have Class A + X endorsement
So thats

Only in parallel Universe

Shhhh growns ups are talking

 

It's obvious you believe anything you read without applying logic or questioning agenda.

Let it go...hmmm, seems Im not the one butthurt that SOMEBODY doesn't give me "what I want" in a rear brake. I'm not the one wrapped around the axle for disk brakes.

Yes, I have a clue what I'm talking about. I've given several different explanations for whats going on. You have just made unbased statements and a link to an article that I think you don't understand fully.

you said purchase price of CMV ADB's. Sounds like a peasly $1000 for the front axle. up to 4500 for all three? On a $100,000 + rig makes a difference? People spend $1000 for just a damn nav system if disk brakes were safer or more durable over the long haul carriers would be getting them for the last 20 years. Fact is once you account for the extra weight and cost of servicing over the life cycle of the vehicle they get more expensive yet.

Excerpt from todaystrucking.com...
Why, then, have North Americans not embraced air disc brakes?
Chad Mitts, Meritor's general manager for North American Brakes says there are several reasons why North American fleets lag behind the Europeans in ADB uptake:

• In Europe, the OEs decide what the truck is going to look like. North American truck makers build the truck the customer wants; in Europe, fleets get what the manufacturers build.
• Different service infrastructure: Most European trucks are serviced at dealers with factory-trained technicians. Here, trucks are serviced by fleet technicians, jobbers, dealers, etc., which makes adoption of new technology more difficult. You have to deal with new parts and new procedures, and there are technician-training issues to overcome.
• Our longer conventional trucks are dynamically different from the short-wheelbase EU cab-over-engine trucks. A typical North American conventional has a completely different distribution of brake work in a hard stop. The benefits of ADB are still there with our conventional tractors, but they are not as pronounced as on a shorter wheelbase COE models.
• North American fleets are very cost-sensitive, and as long as low-cost options exist, they usually get the nod.

Bottom line is disk brakes on the rear of most vehicles is an expense and complexity that is NOT needed. You want them, fine..write Toyota or go buy a Colorado.

Blue T of all the people I've ever talked to in the trucking industry and talked about trucks, I do believe you are the first person I've ever heard wanting disks on a semi.

Class A with x AND t here. so there. lol.

 

Just put BlueT on ignore. Your entire Tacomaworld experience will feel better the moment you do .

 

What's BlueT going to do once everybody starts posting pics of their new '16 Tacos? Probably sit in the corner with usafwx and touch each other while looking at 1gen pics.

Edit: clarity.
