ST205 Brakes Upgrade Options

[Kiolofunk]

Hi guys,

There have been a lot of threads about this however, mine is somehow unique so i wanted to create my own thread. I have an AE101 Corolla with a 3sge rev3 motor in it and converted to ST202 brakes. I recently purchased a complete ST205 superstrut front and rear brakes from a for dirt cheap and since this is my dream brake setup I'm willing to go through all the trouble just to fit it in.

A couple of things I need to put out here is that I'm from the Philippines so sourcing bits and parts may be a bit hard.

Just for background here's how my suspension are coupled with everything just bolt in (no modifications done):
Front:
- ST202 JDM spec McPherson single pot caliper and rotor, knuckle and AE101 balljoints and brake lines
Rear:
- ST202 JDM spec rear single pot caliper and rotor and brake lines

I cannot get a hold of a Cadillac Catera 2002 rotor. It's just not available in our country.

My questions:
1. To get the caliper bolted in, can i simply thread tap the knuckle and bolt it right in?
2. Will i need 3mm spacers?
3. Do i need to change brake lines? (If yes, that's fine as i would really like to get ss lines on them however, from what car?

Now for the rear i have no idea. If anyone has links that can help me. I have saved Culpable04's posts so i have that for reference however, if anyone else has any more info that would be greatly appreciated!

Thanks 6GC!

if you converted to the ST202 hubs then you should just be able to follow the guide and go about it that way

It's a 14% upgrade if you get the Avalon/Camry/ES300 twin piston calipers. They are direct bolt on to your ST202 brake bracket

Thanks for all your responses.

Thanks for pointing that out. I've read that before and I will give it another go.

What if i am to use an ST205 caliper and rotor from a superstrut? That does make any difference?

I could've gone that path however, I've bitten the ST205 brake set already. No going back! Heh.


I think it would be best for me to take everything apart and see for myself as i really have no clue. Will post soon! Thanks.

[Tigawoods]

the ST205 Caliper and rotors only came on the superstrut so thats what we have all used for our conversions.
You wont be able to use the front rotor from the ST205 on the fronts though

seriously dont waste your money anymore.

Tigawoods has posted a true and accurate way to use the calipers.

st205 rotors have to be reduced in size, and you need a machine shop to do it, and its not cheap. plus the cost of rotor, and difficulty obtaining.

other rotors have been tried, and no such luck. ive bought wrx, and brz, and not good options.

[Tigawoods]

refer to the sticky ST205 Brake Swap thread as we are slowly collecting more info on front rotor options

[Kiolofunk]

After reading through the guide and several forums. You guys are indeed right. Reason i got very confused with the guide as i saw various postings of rotors which at first i have no clue as to why but now the light has came down upon me!

Luckily, machine shops here in the PH are very abundant and having the ST205 rotors machined down to 300mm would be a breeze and will come cheap ($20 a pair i assume).

About the rears. I read that the dust shields need to be trimmed down so that's ok. But what about spacers on the caliper holes? Can someone explain further?

Here they are.






They just look a wee bit sorry and having to inspect them I'm contemplating whether i should do a complete overhaul or just clean em out for now.

[Tigawoods]

the spacers are so that the disk will sit centered in the caliper IIRC

[mkernz22]

It's not a spacer, it's a 0.9mm hub-centric ring.

Any of the non-gt4 celica's have a 54.1mm hub bore on them, however, the GT4 has a 55mm hub bore. Why? no clue.
So you need a 0.9mm ring to make the disk hub-centric.

[njccmd2002]

i did not use a hub centric ring. they fit snugly

thats not what he was talking about. he was talking about the washers that go in between the caliper and the mounting hole

Yes i was talking about the washers that go in between the caliper and mounting holes.

Have not had the chance to install these yet but could well be in place by early November.

I didn't even think the camry would have a twin piston caliber! I'm really going to start looking into these now. do you know if its just the 90's Avalon/Camry/ES300 twin piston or the early 2000's will also work? thanks for all your help with celica's bonzai. i don't think i would have been able to do have the stuff on my celica if it wasn't for you (and batman of course)

[BonzaiCelica]

do you know what stickies are?? check in the suspension/braking section..... the info is there...
