brakes

Yaris brakes are crap.

The problem with the NCP91 Yaris is that the brake disk cannot endure sustained and repeated stops. The Japanese RS and some European RS/TS models were slightly better due to rear disk. The current NCP131 Yaris RS/SE has larger front brakes to address the known issue. I set a personal record in September for the shortest OEM front brake disk life, which was 19 days since new.

I've taken some heat (no pun intended) about something being wrong with my installation or break-in procedure because others have experienced no issues with their brakes during autocross events...
Bullshit.
I'm the one driving my car. Not them. Doing 180 km/h to zero stops repeatedly does wonders to the material limits of our factory braking system.

Your options are to improve cooling or swap in front brakes from the NCP131.

There is a lot of fail happening here.

What kind of event are you doing that has you going from 180 km/h to zero repeatedly?

What kind of crap pads are you using?

Nobody is working Yaris brakes harder than we are, and we have had zero issues with the OE rotors and calipers.

The only time I've ever felt the brakes we're inadequate on the Yaris, were with the stock pads, driving through decker cyn road in Malibu. My rotor temps hit 700 degrees, hot enough where the paint on the brake pads caught on fire. Since I've switched pads, I've never felt the brakes as being lacking.

+1

Agree Jason and the best test bench is always the race track. Always appreciate the info you provide.

As for slotted or drilled rotors.........useless. I spent some time at the track this summer and no one uses them. Drilled/slotted it's all show and no go. SS braided lines at the wheels and top quality pads/shoes.

I beg to differ, you do not know how we all drive, as a group or individually. I did the Richard Petty driving experience at Charlotte and Bristol, and I am more of a short track guy (did better at Bristol), I definitely have been, as Mark Martin described himself, "on the edge of out of control".
I was and still think it odd/crazy/stupid/but fun that at times I drive my personal cars harder than those race cars on a track.
So, understood on your points and thanks.
More specific on my warp is only when I am spirited driving it starts to after repeated use, but not everyday driving, it stays OK, but, I just have borderline run out. Too, looking closely, I do not need to even change my pads, but will soon, wife's Camry needs a tune up, and whatnot first on list.
But, you definitely cannot say you ride harder than any one of us, as you do not know how we drive.
That said, I do agree with you stock Yota set up is great, we just want greater, and spend as little as possible to do so.
To have the Lexus handling type car while spending just a bit more than a Yaris. I love pissing the Lexus owners off when I crack into a corner at a much higher rate of speed than they can and it sticks like glue. (Just need a higher rate of spring and I can take a 90 degree turn at 50 mph with out front tire rub as it currently would do if I did, as I have done twice)

A Richard Petty driving experience, and something that sounds like street racing. You are so overqualified. The fail in this thread continues.

I mentioned the driving experience only to mock myself for how hard I am on the car sometimes, but also to enlighten you and the false statement you had, knowing you drove the hardest of them all, and not really knowing that fer sher



Actually, I started this thread, as there really was no real stickie or good info on other options or any options for that matter and wanted to help myself and others, as to what is available, didn't really start the thread for a bashing by the almighty racing clown, then get bashed again.

I have more than 480 certificates (in multiple manufacturing brands) in automotive, electrical and tires and do not claim to be the know it all, actually try and help, and be helped. I have been working on cars since 83 helpin pa, 84 in school, then on personal or girlfriends cars until 89 then part time until 97 then full time since then, but, dude, I do not claim to be all knowing.
I came here looking for tips and tricks, saving me time and helping others when I can, as much as I can.

There are some good techs on here that we want their advice, what they did on their brakes and what they recommend. I merely also stated what I was doing as well.
Feedback good and bad is good.
Fail troll is not.
So, you are either here to help or to not.
So far though

Lets turn the thread back into what we all can do to have the best brakes and the cheapest way to do it. As well as some pretty ones and some racy ones and plain jane ones. And newer Yaris ones, or older Corolla ones. And so on.

Lotsa good input so far from many thanks.
Hopefully no more bashing from the race clown: barf:

Great post. Is that English?

You can't help those that have made up their mind despite evidence to the contrary. Some guys are just so "street" they can't believe they are doing it wrong. Lol

What you call warp is pad material bedding into the rotor, that only happens when you stand on the brakes when their really hot sitting still. Like I mentioned before I've seen my rotor temps hit 700f, I didn't get the pedal vibration once. I've been to SC not a whole lot of mountains there, so not a whole lot of reasons to be riding the brakes like a $2 hooker.

Cool, thanks for the info.
Yeah, I try n use the gears, rather than stand on em in extreme circumstance, not as often as this thread makes it out to be.

Huh.. I have no idea where you get this info from.. It is possible you had a faulty part from the factory though

Been autocrossing my Yaris since I bought it with 20 miles on the ticker. First autocross with my yaris had only 100 miles on it.. I literally autocross once a month since 2010 when I bought my car. I actually just changed out my brake pads the beginning of this year for Hawk HPS which in my opinion feel just like OEM but Hawk doesnt make HPS+. I still had about 30% life left in my OEM pads with 75k miles on my car....
