bleed all 4

x2
bleed everything starting from the rear pass side.

[Culpable04]

I personally bleed 3 out of the 4 and I really hope my friend didn't forgot the bleed the other size all 5 times, but I'll give that a try again and see.

The brake pressure difference between these calipers should not be all that different... I mean... most big brake kits use the stock master cylinder, so I highly doubt you're lacking pressure. I think there's something else wrong.

if you have any ideas of what else I should check, please tell me so, I ran out of ideas, at the beginning I though maybe the cylinder is bad, so I replace it with a new one, and everything on the front is basically new, the rear are untouched, I'm gonna bleed everything again as suggested, so if there is anything else I should check please let me know guys.

Well after august i'm planning on doing the front 7th gen big brake conversion--thiknin about getting slotted/drilled rotors and brembo calipers, and also planning on changing out the rear brakes to st205. I think I read somewhere that it would fit, or was that for the ST version only.
My concern is, with a big brake kit in the front and oem rear st205 brakes in the back. Will there be an uneven distribution of braking power, will it cause the front to wear more sooner?
Also, I tihnk there were big brake kits available for the st205 is that correct? So theoretically, the big brake kit for the st205 in the rear will fit on the ST (GT is possible).
Will this fix that uneven braking problem?

So did you end up finding out the issue?

[Culpable04]

Brakes fixed

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.

pics stevenson. I want to see how much bigger they look compared to our stocks.

I know the pads and rotors are different but you replaced both the caliper and the torque plate right (caliper holder) ? Or just the caliper ?

start with the farthest away and work your way around.

the torque plate has to be replace as well in order to fit the bigger rotors, but I had to use the bolts from the ST ( from torque plate to hub ) as the bolts that came with the GTS set were too long and were going to hit the back of the rotors.

I'll take pictures tomorrow, it was cold and I'm still a little bit sick so I didn't wanna stay out for picture taking but I'll do it tomorrow for sure.

The difference is size with the stock ST is ~ 1-1.5 inches, I don't know if this would be consider an upgrade for teh GT guys ( or if they fit ) but for the ST is definitely worthy, I had new brake pads installed last summer and the brake felt nice, but the difference with this set-up is night / day. I know is not fair to compare since I also have SS brake lines, and fresh fluid, but I don't even have to press the pedal much to get the car to stop.

Glad you got them working!
Id like to see how they compare to stock GT brakes.

[bccentaur3]

Same here. If there is even a tiny bit of gain for the GT I might just get these since they are hella cheaper than a bbk up grade.

[Culpable04]

pictures are taken, when I get home I'll upload them for you guys, I don't wanna get the IT department mad again, they don't like unkown activities on the server especially if they can't track them lol

[fanboy95]

i want to see this too. i've been looking at all the options for brake upgrades and not sure which to do.

[Culpable04]

these are the pics I have right now, if you guys want / need anty specific shot let me know and I'll take it.

[Daftboy]

You know I was thinking...and did some research a Pontiac Vibe 03-04 may fit as well since the vibe is a Toyota in reality and i think they use the same brakes as well...not sure thou.

[Culpable04]

pontiac vibe
toyota matrix
7th gen celica
scion TC
and some corollas have the same caliper, but the rotor may not be the same due to off set differences.

vibe has same offset

this needs to be added to the other parts that fit our celica topic...

[Kwanza26]

As I may have already mentioned, this would be a good mod only for the ST guys. The size and performance difference between 7th gen brakes and 6th gen GT's are insignificant. However, for the entire community as a whole, this does say 7th gen Big Brake kits will probably be bolt-ons... =D
