Bremo Brakes..on 6g Options

[lubu]

I found these on eBay, but are they bolt-on or do I need to modify them to fit...btw does the price sounds right??

What would imply they'd be bolt on? For one... you need bigger rotors assuming the calipers do bolt up, which I doubt they will without a custom bracket.

The second one do come with rotors. Hrms, maybe its harder then I thought.

[doGGy]

been there done that... Tryed to fit Evo8 brakes on my ST and on my SSIII.... Not even close without major constructing... Even if you do make spacers, you will need to source brake disks with right ET to fit brake calipers... Too much hastle - honestly, and i would not like to drive a car with somthing thats been modified / and not tested...

For SS suspension people - get GT4 brakes / disks - this is straight forward swap. So Mac users - i think GT4 brakes would requer less modifications to fit then these EVo brembos...

Thanks for the reply doGGy, I figured that it would be harda$$ and potentially dangerous too. 205 caplipers it is.

Tried the ST205 brakes, but went for OEM size Brembo blanks and Ferodo DS2500 brake pads. To much hustle for the ST205 brakes to fit.

But Sthen (from Italy) has used them on his mac suspension. Maybe he can give you some info about it.

Okay I was wondering if anyone on 6gc.net did the 205 conversion brakes on their 204. Coz Im thinking of upgrading but Im unsure abt the procedures. I'll have the calipers and the rotors, I was told that I need some custome brackets made. Any inputs are greatly appreciated and pictures will be splendid.

Try PMíng or E-mail him. Because I dont know anyone else who has done it on a mac suspension.

THanks Kadett, much appreciated. Hope he returns my email.

Great news:

I did a bit of research and I came across these pictures.

According to azian_advanced's measurement the distance from the two ends of the calipers bolt holes is 142 but if you look closely the distance from the centres bolt holes is only 130mm.

Now I've found a fews pics regarding to the 205 calipers' dimensions and susprisingly the distance between the bolt-holes is the same (for the fronts at least).

So no customs brackets need to be made, and thats to me is very good news. I suspect that if you have the full set (rotors+calipers) then its not as hard as it sounds.

Im on to this like fly on ...... !

[Kadett]

I could have told you that the distance between the mounting points are the same. Its a distance used on many Toyota's, f.e. the MR2 has the same distance.

The problem is that the offset does not match and that the caliper wont fit over the brake disc. So you would have to grind down the 315mm disc to lets say 280-290mm to make it work (only using washers to fill the gap for the offset. But I dont think thats a good solution.

The problem then is that you have to extend the caliper with a bracket. But the distance between the mounting points on the hub and where the points would be for the correct fitment is to low. So the distance between the holes would be dangerously close. Or about overlapping each other.

So you have to 'rotate' the ST205 caliper so it goes a bit up and thus having save enough room between the mountingholes on the hub and where the ST205 Caliper should be extended to. Without a spare hub (i dont have any and no Celica's in the junkyard) its impossible to measure from under the car.

found these pics online..




this bracket isn't necessary, just get a longer bolt and mount it in reverse:





and you need to do quite a few things to get the front st205 calipers to fit...
a) longer wheel studs
b) longer brake line
c) shave off 1mm off the caliper mounting locations to bring them out forward (so the disc will clear the bottom ball joint)
d) the disc itself will need a 4mm spacer to center itself with the caliper
e) the discs will need to be machined down to atleast 297mm in diameter
f) longer caliper mounting bolts

for the rears, it should be a direct swap using st205 caliper, discs, and pads.

these are the steps i found that were used on fitting the st205 brakes on an st185.

Thanks for the inputs guys, yeah I was wondering if the steps are the same for 6gc..Oh well guess we'll find out how hard it really is.

BTW no one else on the forum has done this beside Sthen??

@azian_advanced:

Those links and specs are designed for a ST185. SveNRG (fellow Dutch 6th Gen owner) had ST185 discs/and calipers on his AT200. And those were grind down.So if a ST185 owner needs to grind down the ST205 discs to 297mm, a ST202/ST204/AT200 owner would need to grind the 205 discs down about 1-1.5cm further then 297mm.

And for the rears:

They will never fit unless you remove the handbrake assembly, even then I dont know if its bolt on. The ST/GT handbrake assembly (handbrakepads etc etc) is larger then that of a ST205. Difference is about 2 cm's in diameter.

Kadett that sounds logical, but there are two versions of 185 brakes, one is the single piston with larger rotor and the other is twin pistons with smaller rotor... If he installed the larger single piston grinding down the diameter of the rotor makes sense.

EDIT: Acutally ur right both of the 185 use the same rotor diameter (288)..my bad

Here is a list of the diameters and dimensions of some celica rotors:

I had a whole ST205 wreck at my disposal. Still have the front rotors/calipers laying around. So I tested everything I could about swapping the brakes. I would have kept the rear brake parts but didn't want to fuss with a hydraulic handbrake or somesorts.

And my front calipers need total overhauling = 400 Euro in parts alone

I know you've been answed, but looking from the picutres they seem pretty beat up, why not just buy a kit from somewhere a little more reputible? When it comes the brakes its better to be safe then sorry.
