Is there a rear disk brake upgrade?

With as much vocal "outrage" against Toyota for continuing to put drums on the rear for no real purpose, is there a rear disk upgrade for the tacos available? Would be nice to see an OEM engineer come out and say "Yea, we're gonna offer this to you guys as a factory upgrade".

I'd rather it come from toyota and be covered under the warranty than have to go to aftermarket...

 

SOS performance

 

Thank you!

 

Do those retain the ABS and the parking brake? I'd love a cross drilled / slotted rotor that came with all the bells and whistles.

 

If you go that route, be careful what you select.

There's a reason many HPDE and autox drivers avoid aftermarket selections of those. Once you see ones crack, chip or outright fail, regular old vented rotors look pretty nice.

 

Yea, they have to be cast with the rotor up front, otherwise the heat cycling will stress fracture. I'm well aware of the risks of the rotors.

 

Avoid fully cross drilled rotors. I have EBC slotted and dimpled rotors on my S2000. They have been on maybe 6-7 years and 30k and no issues at all.

 

Not sure why people think this is important.
Brake bias is all front.
Drums stay cleaner and last longer.

 

Drum brakes are self energizing. They have a habit of locking up. If a modern car wants to tout a whole bunch of tech features, and doesn't take advantage of modern disk brakes.... why? EVERY high performance sports car does, why hold back on a pickup that costs $40k?

 

What evidence is there they have a habit of locking up?
Disk brakes are not modern... they’re over 120 years old in design, have been used in racing since the 50s.
Other manufacturers put disks on the rear for whatever the reason may be, lower cost, or ignorant consumers thinking they’re better... but reality it’s just not.

 

They're self energizing, again. It has it's perks and flaws. In a semi, when they apply the brakes, they typically need to, and a brake system that continues to add more and more friction is more often than not a good thing. In a passenger car, not so much. Let us also not forget the moment arm necessary to create a counter force against rotation to stop that much mass. A disc brake is just not the best solution in that case.

 

It's a common physics (engineering) to describe the materials as they heat up because of friction. The fact that the materials will expand during operation necessarily dictate that a drum brake has far more likelihood of locking up than a disc brake setup.

 

I hate to tell you this, but your 40k truck is Not top of the line. I have to chuckle everytime I hear someone say, I paid 40k for this truck it should have everything.

 

Did I say that? No. But for a truck that costs as much as it does, I'd rather have engineers explain how a rear drum is better, instead of "it cost less".

 

Cool, I´m out before something bad happens.

 

Which is compensated for in the engineering design with the retraction springs. It makes for an elegant solution frankly, requiring less force/energy to activate.

Your statements are illogical and untrue. If drum brakes had any higher potential to lockup they would not be in service on consumer vehicles.

What other reason of disk superiority do you have?
