Brakes fixed smile.gif

it was exactly what you guys said, I bleed them again in the order you guys told me to and that was it.


so far I love this upgrade, the brake are more responsive, and have a better grab and the best thing they don't fade after a fun drive thru some turns.

Ok.
So I read up on this.

It seems like a reasonable upgrade from stock for us ST guys.

So I have a line up in parts that I want.

Rotora drilled and slotted front rotors for the 7th Gen GTS: $205
Rotora pads for the 7th Gen GTS $60

Those are supposed to be OEM upgrades.

As for the 7th Gen GTS calipers...
How much?
And where can I pick a set up?

What else do I need?

I got my set from newcelica.org smile.gif and don't forget to grab some SS brake lines so it's a complete upgraded system.

Do 7th Gen GTS rotors fit on stock 6th Gen ST calipers?
SemperFiMarine

Damn.

So where can I find a set of 7th Gen calipers for a good price?

Definitely not the dealership.

try newcelica.org or any 7th gen forum

I went to new celica.org...
I couldn't find the link where to purchase parts.

so, if 7th gen front brakes are a big upgrade for ST's, but would probably not be an upgrade for GT's, then wouldn't just putting 6th gen GT front calipers, rotors, and pads give the exact same benefit to ST guys as 7th gen brakes (assuming that 7th gen brakes are not an upgrade for GT's)


really off topic, but I noticed in the picture that you have hankook ventus HRII tires. I was wondering how you like them?

there is no link where to buy rolleyes.gif , you have to make a WTB post

I'm not sure about your comparison, you might be right, but I don't know it lol

about the tires, they are the best for the money, I paid US$220.00 for a brand new set, traction is great on dry, not so great on rain / snow, but it's drivable. Remember I have a ST smile.gif so keep that in mind.

Would these fit with stock rims?

No 15's will not fit. I had a 7th gen gts and tried to fit 15's for winter, but won't clear the calipers.

I know that the uprgade to disks all around is good, but besides disks all around what are the pros and cons to this swap??

Its obvious in this case bigger is better. Since our braking power is used more up front having bigger rotors and disk gives us better stopping power. Of course all wheel disk break will make a difference too. Especially for you ST guys.

I'd say that if you have an ST, upgrading the rear drums to rear discs, AND then upgrading the fronts to 7th gen GTS/6th gen GT (if they work, but I don't see why they wouldn't), you'd have about the same as a stock 6th gen GT, but it would be a huge improvment over a stock 6th gen ST.

Well when the 3s gets running I'll definately need some bigger brakes... I dont drive fast but i like the look. And its always nice to be able to stop fast when its needed.

either way its always nice to know there are other options out there for our celicas.

they 'are' an upgrade for GTs (assuming they fit the same was as on an ST), but not the same kinda difference you would get from an actual bbk. i'm sure the 7th GT-S brake assembly is bigger than the 6th gen GT disc brake assembly.
once i find someone local parting out a 7th gen GT-S, i will try this myself!

Kwanza posted the specs of the disc, they are about the same size, the only way this would be an upgrade from GT is if the caliper and pads are bigger, probably GTs can just swap the caliper instead of having to get new disc like us ST drivers

well, if they do in fact need 16's to clear the caliper on this car (i know you do for 7th gens, but maybe our's is mounted slightly closer or something, I dunno) then it would be bigger then stock 6th gen GTs which can use 15" rims.

if somebody had the measurements on the diameter of the caliper piston on 7th gen and 6th gen GT brakes, that would tell you right away if it would be an improvement.

lubu also posted a chart of rotor sizes.. and the 7th gen GT-S and 6th gen GT have identical rotor dimensions but the 7th gen is 3mm thinner.

my assumption is if the 6th gen GT calipers and axle carriers are the same as the STs (which i'll verify when i get home today), then the 7th gen GT-S calipers will mount to the 6th gen axle carriers and won't need to have 7th gen GT rotors (if the 3mm thicker rotors from the 6th gen doesn't affect the 7th gen calipers' performance). but all this is pointless, if the piston diameters of both calipers are the same.

3 mm thicker will make a difference, that means swaping the caliper to the GT and keeping the stock rotors will not work, the piston will travel a different distance in order to compress the pads, a thiner rotor will means that the piston will not travel enough to apply the required pressure.

Can't somebody who has part numbers confirm if the brake parts used are the same from ST to GT? Just a thought.

but that's not the case. the piston moves closer to the disc as the pads wear out, and when you release the brakes, it moves back only a very small amount. for example, when your pads aren worn, the piston sits closer to the disc, this is why you push the piston back in when you put new pads in. then after a brake job you pump the brakes to get the piston to the proper position. the thinner rotor may or may not cause problems for other reasons, but the distance the piston needs to travel is not a problem. the only problem I could see with it is that when the pads get extremely worn, the piston may extend too far to the point where it'll blow the seals in the caliper.

^ that, and also the possibility that with 7th gen calipers, new (thick) brake pads and the thicker 6th gen rotors, the extra 3mm rotor thickness might be too much...

anyway, i just checked the ST and GT brakes... they have the same caliper mounting bolt distances, same steering knuckles and same hubs.. i don't see why it wouldn't work on a GT. we just need to get this confirmed now.. any takers?

the 6th gen GT rotor is 3mm thinner than 7th gen rotors, not thicker. there shouldn't be an issue with the rotors/pads being too thick to fit in the caliper.

I'll put them on and test them out if somebody wants to give me the calipers tongue.gif
