how to: Mr2 to GT brakes at a reasonable price, Bolt on Caliper Change. Options

[Culpable04]

I have to take some time and calculate the ST205 stock Bias, and then install the rear ST205s on my car, depending on how it performs I may need an adjustable proportioning valve, but time will tell.

for now I can say, that this is a great setup for someone who doesn't want to get too complicated and on a budget, it changes your brake bias to improve braking without having to actually play with proportioning valves an such, at a very low cost.

Great Job Norberto !

Someone forgot to mention SS-II non superstrut has the same 2pot as SS-III 2pot, Right Rusty?

Only SS-I has the same 1pot as USDM GT.


Mr2 is a way lighter car than Celica so doesn't need as strong brakes.

acutally ss-III and g limited both came with 4th gen 3sge and the mr2 actually weighs 1220kg about the same as the celica, if not a little more if I remember correctly

ughh so sad what a 300 pound weight advantage can do

Superstrut SS-II and SS-III have Twin Pot front brakes. (And I think the SS-II superstrut brakes were bigger than the SS-III, larger rotor)

SS-II has the Single pot front brakes


But as I pointed out....

The single piston caliper specs (SS-II):
Piston Diameter: 57mm
Piston Count: 1
Total Piston Area: 2551.76mm² (25.5176cm²)

The twin piston caliper specs (SS-III):
Piston Diameter: 40.4mm
Piston Count: 2
Total Piston Area: 2563.79mm² (25.6379cm²)


It's only an increase of 12.03mm² (3.47mm x 3.47mm)

[delusionz]

I thought when we compared brakes (when I had SS-III) that you said yours looked identical?

[Rusty]

Don't think so, im pretty sure that was you

Regarding the SS-II having single piston calipers, I have something to add...

My ST202 cut is from a non-superstrut SS-II



Yet it has twin piston calipers:





Here I've used a torch to show the non-superstrut suspension:



And a couple more pics showing the markings:





I'm not a Celica expert, but I'm pretty sure what I have here is a non-superstrut SS-II with twin piston calipers.

Thoughts?

[njccmd2002]

yes!!!! you are a lucky man!!!!

[BonzaiCelica]

wow interesting. And for the love of god re size your pics its so annoying when members do that!!

[Rusty]

Yes you do

From Discussion thread about LSD's in the ST202 SS-2's & SS-3's

then after 97

the SS-2(beams) & SS-3(non & beams) run the same TRD pads, so they should run the same twin pot front brakes
(check Japanese TRD website)...and on Toyodiy (however slight difference in part numbers)

They (ST202 SS-II [BEAMS] & SS-III [BEAMS]) both run "twin pot brakes"... However the part numbers are different, it could mean nothing, or a difference between the two, which is why I didn't add it ....and I sort of forgot
(example : 1998's SS-II & SS-III)


Would be good if you have time to take measurements so we can compare.

[S8S8]

No worries. What measurements are you after?

[Rusty]

the same above measurements so...

The twin piston caliper specs (SS-II BEAMS):
Piston Diameter:
Piston Count: 2
Total Piston Area: mm2 (cm2)


and rotor specs

circumference
diameter
width

this Sticky thread is useless without pictures!!! norberto jump on it.

Which brings me to another topic, hey S8S8 can you give us that answer. We are curious to know whether SS-II Beams and SS-III Superstrut Twin Piston Brake Calipers are the same size???

Dude, you are so needy, just like andrew, are you sure you two are not brothers.

ya i know right sorry man. Did you change to flickr. Must be an age thing....

I'll be changing the pads soon and will run the measurements then.

[BonzaiCelica]

measurements of the twin piston calipers on SS-II Mcpherson Beams Celica???

[urbandork]

Out of curiosity... what is your interest in bigger brakes... what are the current symptoms that you curing with a 2 pot caliper?


Those look like Calipers from a ST165, no? Probably not as they allegedly bolt up without issue.

if this is true someone over on alltrac.net did a write up on how to use tacoma brakes on a st 165/185

i have a set of front gt st204 calipers and i think a set of st185 calipers... perhaps ill measure them when i get a chance.... i also have access to st205 front calipers. maybe ill see what i come up with.

[BonzaiCelica]

is fensport correct??

if you see this link you see that they mention the ST202 Superstrut Celica, AE111 Corolla Superstrut, MR2 Rev 3 N/A and MR2 Rev 3sgte all use the same brake pads http://www.fensport.co.uk/Parts/Model_14/Category_11/2672

but if you take a looky here on toydiy you can see that the pads from 1999 Celica SS-III Superstrut only share common part numbers with carinna and corona cars. http://www.toyodiy.com/parts/xref?v=J_1999...mp;s=0446520230

Here is the ST202 Mcpherson SS-II twin pot pads. http://www.toyodiy.com/parts/xref?v=J_1998...mp;s=0446520470

here is 1990-1995 SW20 3sgte MR2 http://www.toyodiy.com/parts/s?v=U_1993_TO...1%E2%80%9117160
brake pad : 04491‑17160

for some reason I can't find any part numbers for the Corolla AE111 brake pads. toydiy does not list part #'s

ST202 SS-II Beams Mcpherson brake pads : Part 04465‑20470
ST202 SS-III Beams Superstrut brake pads : Part 04465‑20230

or so I think damn I'm so confused.
