Big Brake Kit Discovery

Centering the disc should be done by the hub not by bolts. And of course i would never modifiy a brake caliper this way.

Atleast in Europe that kind of engineering is strictly forbidden.

That's a good point. I didn't see that when I first looked. Some rings to center the rotor might be a smart thing to do.

Consided a caliper brake on a bicycle.
You need relatively little caliper pressure on the rim as compared to the pressure you would need if it was close to the hub.
It's just basic physics.

This thread haz revolutions...

Yeah, that's what I posted earlier about the angular velocity compared to the linear at the rotor edge.

I'm sure the OP is wondering what happened to his thread. :-)

lol, atleast it didnt turn into an oil thread.... lol. everyone on YW kept themselves in check.

im excited to see how the new disks work out. maybe even some pics of them mounted. i would be very interested in a set as my rims look naked inside.

Seems like 10" discs brakes front AND back would fix the 2200 lb Yaris nicely...and kit for that?

lol, no not really, its good conversation and some valid points. i know not everyone understands the math behind angular and linear velocity so carry on.

yes i am also glad it hasnt turned into an oil thread yet

i know the hub bores are not the same size and i measured the play in the stud holes and the rotor can only move .003 in any direction and .oo3 off center doesnt bother me.

its been raining here for a few days but ill try to get some more pics tomorrow, they do fill the wheel up nicely.


as for brake function at slower speeds just cruising around town they feel stock, but at higher speeds and pedal effort it stops, it stops very well. i cannot really quantify it or anything but i can say it stops alot faster when you need to, i will still have to see how the next track day goes but as of right now i have to say best upgrade thus far

[ilikerice]

after reading this post, i think i have just been mind raped...

[yaris2010RS]

how much was the kit? and i am more worried about the wheel feeling off balance because of the .003 (inch) give of play

ive had it sitting around, took it off a ctr that we put stock brakes back onto to run smaller wheels, owner didnt want them back.

i was looking around and ive seen used kits for sale on honda forums for $100-$200.

ive already had it on the highway and various speeds up to 90 and no vibrations. so balance doesnt seem to be an issue

If the Calipers mount at the same points or at the same distance from the Axle Center, there is no difference in the braking at all, so nothing changes except the size of the rotors.... That'd be absolutely pointless... Hope the Caliper mounts are away from stock, and SECURE. Just my 2cents...

So what gen civic was the BBK off of?

[Viperoni]

The extra rotor diameter will at least give you more mass to absorb heat and more surface area to sink it away. Useful in racing.

Where's the OP with a final review, how are things holding up so far?

[seth_man]

Sorry for the delay everyone, ive been very busy with work, wedding plans n such.

so ive been to 2 track days since the rotor upgrade and about 2k miles street driving and everything is holding up great, no issues at all, i dont know if you can consider it an issue or not but finding 12.9 hardware to put in place of the stock caliper bracket bolts was not easy. M10x1.25x45 flanged bolts are not easy to find.

The first track day was done on stock pads and i was pretty impressed. there is a very noticeable in stoping power and much less pedal effort to get the desired braking. after the frist track day my new pads finally arrived. stock replaced with hawk pads. second track day was even better with the new pads. it took a little getting used to braking so late for corners i found myself nearly stopping before i got to a corner off a high speed section. it now seems that i can hold off breaking 40ft or so closer to a corner than with the stock pads and rotors. overall this car just became alot more fun.

Sweet!!
