The brake story: frequent disk warpage

You can certainly install the whole ncp131 rear disc on your existing rear axle but a custom mount must be made for the caliper, behind the hubs. You will need ncp131 rear discs/caliper (09 corolla xrs calipers have been reported to work also..dont take my word for it) and ncp131 ebrake cable, since the ebrake is direct caliper to rotor...no drums.

Mate, THIS is the raw technical information that I was looking for... no drivel about wheel torque or braking technique. Thank you so much for this. A diamond geezer, you are, truly.

Indeed, the mounting location for the rear calipers are different for our drum-type axle, which is why I'm inclined to swap the complete axle assembly-- for direct fit and OEM quality. Going back to my first post: "quality and reliability are absolute; nothing else matters."

Would you reckon anybody here would know the technical details regarding NCP91 vs. NCP131 torsion beam axle mount geometry? I personally don't suspect them being different, but anything could have changed year-over-year thanks to NCAP and NHTSA. Also, where did you find your NCP91 rear axle?

I reckon that your current brake configuration is the dog's bollocks; quite impressive. Do you have pictures? How is the stopping power and bite consistency after abuse?

Wow.... very classy. Keep in mind that you posted here asking questions and looking for help. Maybe next time you post, let people know beforehand that if they don't tell you what you want to hear, you aren't interested. It will probably save you from having to read such drivel again.

Loaded or not, the Yaris does not have inherent issues with brake warping. Yet if I want to, I can easily warp them in less than 15min by lousy "driving technique" (I've done it before). Simply put: It is most likely that your "driving technique" is the cause. Just because your ego doesn't like it, doesn't make it false.

We have yet to warp a brake rotor on the Yaris, and we beat the snot out of them. I suspect you are more likely seeing pad deposits on the rotor, which give the same feeling. Try a different pad next time. Maybe Hawk ceramic for street use, or HPS.

funny enough i got it off ebay, before the seller (elady01) started rising the costs of shipping by double for the axle. You'll see the axles every now and then.









the bite is definately there, and very consistant. I cant say about how the car handles during extreme braking because my car is much much stiffer than stock (aka i dont dip during extreme braking)..I can tell you it has saved the car MANY times since i live where the traffic is rated one of the worse in the country, with one of the worst drivers (rich people that accel hard and brake harder)
