3rd Gen Concerns

Yes Disc brakes are better. All of the 2nd gen Trucks have rear drums. They have no braking issues. Toyota has said that they are keeping read Drums and they are also upgrading the braking system.
According to Pickuptrucks.com the rear drum brakes will remain but will not be carryover. They will feature a new vacuum booster and a new antilock braking system to improve how the brakes feel, reduce fade and improve stopping distance.

-- Mike Sweers, Toyota Tacoma chief engineer said:
"Based on these changes and the proven durability of our braking system, the disc/drum was determined to meet all of our criterial for on- and off-road performance and maintain proper brake surface temperatures," he said. "Bottom line is that disc/drum or disc/disc setup will give you similar performance and stopping distance based on system cooling and/or temperature buildup. Disc brakes provide better cooling and reduced mass over drum systems. Drums provide less exposed braking surface and less brake vibration due to braking surface flatness [rotor warping] concerns resulting from overheating of surface."

 

AHA.....now I understand. Toyota is trying to reduce driveline vibration. (why does this ring a bell somewhere in my little brain?)

 

100% true, What would you rather have? Shitty ABS system with drilled/slotted/ventilated discs that are too small for trucks size with ceramic brake pads or proper size drums with an advanced ABS module which is far superior to shitty ABS system?

 

You could argue too that a truck used more for off road has the rear brakes better protected. Using the drums as parking brake helps too. It may even enhance the ABS activated limited slip. Though they are prone to over heating, when used for traction control, they require less power assist and I would argue, respond more quickly. I can't prove it. But the LSD on my drum brake rear axle works well enough to drive in and out of my snow covered mountain road in 2 wd. Once moving, 4 wd is unnecessary. My biggest concern is, if you over use this traction system you are begging for an earlier brake job. Still. The drums work every bit as well as the 4 wheel discs on my 4 Runner.

 

Btw, I have to differ with those who say this LSD is unnecessary with 4wd. There are times on tarred roads when you should not be in 4 wd, but still encounter small stretches of slippery going around intersections. Imagine pulling out on snow, then turning onto a bare road. The drum brakes to a great job with this traction aid. They respond instantly !

 

the irony is too much. Is English your second language or did your school system fail you?

 

Blue T

You didn't understand the study. It doesn't prove your point. So no, its not good enough. So your logic follows the right hand column of your little flow chart above.

 

Strike one.

You missed it junior.






Yes my command of the Engrish wanguage come and go at moment notice.

And yes all the school systems are failing me. They isn't teachen da childrens as good as dey did fo me.

 

Because you don't know how to use the word "anymore" properly in a sentence? Ok.

 

hmmmf

Ok. Grammernazi? really?

Last line was meant to sound as if a child was saying it?

"go away! Batin!"

Brawndo. It's got what plants crave. It's got electrolytes.

Disk brakes. It's got what drivers crave. It's got cool. Scientific nerds have proved it.

 

Sure it was. Next time try a quote from the movie.

 

This thread is beginning to remind me of this, which is related to the idiocracy movie:

 

I miss King of the Hill.

 

My point is "Disc brakes are better" (which is nicely proven in that study) Since Disc brakes are better anybody who is hanging on to drum brakes is just a uneducated <insert word here>...

 

No, your study did NOT prove disk brakes are better. They proved that vehicles with shorter stopping distances reduce severity of accidents.

On a video game driving simulator no less. (LMAO)

...in which they arbitrarily assigned stopping distances to different braking systems into the simulator.

Make sure you click to expand where BlueT posted the abstract to the study which says " The fundamental result this research validated is that reducing heavy truck stopping distance has strong potential to decrease the number and severity of crashes in situations requiring emergency braking.

Also, because you apparently didn't hear it the last forty times it was said....better is not a very specific word. Better means many different things.

Better what?

Better price? no for disks.
Better tolerance to heat buildup? Yeah maybe. IRRELEVANT ON REAR BRAKES. edit: for passenger vehicles endedit
Better as in easier maintenance? Debatable. Depends if you understand how to get the springs off and drum shoes backed off versus having rusty guide pins or a seized hub attachment screw on a disk that's been neglected.
Better modulation and brake feel? Ok advantage disks but again IRRELEVANT ON REAR BRAKES.
Better resistance to mud and water affecting initial brake application? Advantage drums.
Better as in less complicated parking brake incorporation? Advantage drums.
Better brake lining longevity? advantage drums. especially for evenness of wear and getting the most and equal mileage out of both shoes/pads. Disks aways wear out one pad before the other because of dirt/frictional losses in the guide pins.
Better braking force? No Advantage to either. Depends upon design and materials chosen for lining and braking surface.
Better stopping distance? No advantage to either if designed with enough force to lock the brakes and the ability to modulate braking force. Has more to do with the specific tire compound/surface, weight transfer, and brake application/modulation by the operator/ABS system/brake force bias compensator.

Just saying better leads to apples versus oranges.

Which of those "betters" is most important to you. Tell me if there is a "better" virtue that you think is important that I have failed to mention.

 

Meh...yawl just need to know one thing. "If it has tits or wheels, it is gonna give ya trouble..."

 

Lol. We have actually come to the point where someone is arguing that drums are better than disks. Arguing in favor of an inferior technology because that's the technology that happens to be on your brand of choice - is a leading symptom of fanboy disorder. You might want to get that checked out.

 

Checked. Not a problem.

So what about....you define EXACTLY how it's an inferior technology.

Maybe you're just a "technology" fanboi? Companies tell you "you need this" and it's automatic that you do? Might wanna have that checked..

Next up on Tacoma world. Why shotguns are better than rifles.

 

Holy shit ... I am dying from laughter

 

That right there voids the rest of your arguments...
I think if that so called "video game simulators" can handle simulation of Atlas V rocket powered by liquid Oxygen and Kerosene with a trust of 860,300 lbs, lunching satellite into orbit .....
......it can handle a simulation of freaking truck trying to slow down..


To your other comments:
Let me give you a definition of brake (from Merriam-Webster for kids, so you can understand better)

According to that study the main function of brake is performed more efficiently by disc brakes (aka better).
With disc brakes you stop sooner, you are less like to crash into things, and less likely to be part of accident with life threatening injuries.
Therefore Disc brakes are "Better"
Now lets watch some video
