Rear disc brakes?

You beat me to it. Dive is the result of soft front suspension.

If Toyota put discs in the rear people would be bitching about wearing them out faster and “how the old drums would last 150 000 miles and it stopped just as good.”

 

Do those other trucks perform significantly better in controlled braking tests than the Tacoma? No





Has the decision to remain with drum brakes adversely affected sales? No

Again, not as important as some people claim.

 

I called Pedders. Their kit is $1439. They don't recommend a master cylinder change and claimed their kit is tuned to the stock MC. (I'm a little skeptical about that)

All the disc brake haters should check their real world brake testing on the youtube video. The kit reduced stopping distance by nearly 1/3.

Their kit appears to be the similar to the UPI kit, possibly the same. The cost could be reduced dramatically using used parts.

 

Actually, yes they do, not that it matters because there is always room for improvement. Tacoma was second longest to stop empty and longest when loaded, which supports my theory of rears helping more when loaded or towing. Tacoma vs Frontier, Colorado, Canyon, and Ridgeline. Both stopping contests were won by the Frontier.

You have no data to support sales. There isn't an option for disc, and the Tacoma has always been drum, so there is no comparison to run. How many times is it discussed here? Apparently it is important to other people even if not you.

 

You mean the test where it got last and second to last? That's one stop too... discs shine at shedding heat; not one quick stop. The fact is it was done to save costs and no other BS reason that people here come up with. Do they work fine for most people, myself included, yes.

But it took 10% further to stop than the Frontier loaded but only 5% unloaded. Does your own example show the advantage of discs? I'd say that 10% is pretty significant. And yes, I'm bored at work today.

 

Interesting. Regearing would be a good time to make that swap out. That is going to be expensive. Gears f&r, brakes, front locker all seem logical to install at the same time. And on board air if I go ARB over Harrop.


Edit: Does your kit use a standard caliper that you can get pads for at a parts store, or are they manufacturer order item? Looks like that Pedders kit uses a specialty pad.

 

i would rather they got an independent testing facility to measure the brake performance. Anyone who does a test with a vested interest in its result should be questioned. also if it improves the Tacoma braking substantially why arnt the other trucks with rear disks showing that significant of a change in braking performance?

 

They are making the upgrade.

 

Actually, it's the mean average that it would be compared to, not best to worse.

Again, the advantages are minimal for rear disc brakes on a mid sized truck.

 

They are also designing electric Semi trucks. Technology always moves forward, the point is that trillions of tons of cargo have been braked with drums. They’ve been in use for a hundred years because they are cost effective and work well.

 

its 8.9% vs the frontier but also 2.9% compared to the chevy with disks. also having driven the 2016 frontier im shocked it came in first. it had a terrible braking and steering feel. (so bad i still remember walking away thinking thats just not going to be fun to drive)

 

Not really the upfront cost yes drums per axle are around 3k less but some maufactors like pete on some models disks are standard on at least the front axle. Large fleets for example the trash trucks use disks on all axles as they last longer and have less down time when they need to change stuff out. Insurance is also a little bit less and have a had more room for payload as disks weigh less than the drum setup.

 

I said significant performance gain... your data shows it's not. Compare it to the average stopping distance of the disc brake equipped trucks, the difference is negligible

Tacoma still remains the sales leader even after Chevy / GMC, Jeep and now Ford have returned to the mid sized market.

I've owned 5 Toyota trucks since 1986, two for over 12 years each and all came with rear drum brakes. I've replaced plenty of pads and rotors over the years, even a set of calipers once. Never have I had an issue with the rear drums or the ability to stop.

Again, rear discs are not as important as some here seem to think it is.

 

TW likes shiney things

 

With 1000bhp turbo hybrid V6 that gets 50mpg and costs less than $40k

 

The Frontier stops 10%(9.8) quicker. 156.6-142.6=14 /142.6= 9.8%

 

My rear brakes are OEM Toyota parts except for the custom backing plate. I used OEM Toyota pads and rotors rather than the stuff you get at the corner auto parts store because I think the quality is better. In a pinch I should be able to find replacement parts from any auto parts store.

After seeing the Pedders video, I think they are using aftermarket rotors and pads but with the OEM caliper and backing plate. So I think their kit would accept a stock pad and rotor.

 

Yes this! My girl has a 19 T4R and I hate driving it solely because of the brakes. I have to push them so much harder to stop. Now my 17 taco is the right set up

 

Dude, it's 10% better when loaded and the Tacoma is lighter weight than most if not all. That is significant. I have an 81 truck with drums too, that's because it's an old ass truck. Offer it as an option and see what the divide looks like in a year. I would bet money that discs take it. That's like you saying no one needs electric windows or locks. They don't offer ANY performance improvement. How the hell can you defend using drums? The only reason they are there is cost, not performance. The only argument is that you don't want to spend the dollars that it would have cost from the dealer. Other than that, what is the down side of discs?

 

That's cool. My only issue with special pads would be availability in the event of an "emergency" of some kind or the manufacturer goes under or stops production.
