Conversion to the 295mm Avensis brake on the Celica [photo story]

CRX_Fan · Jul 22, 2012

Hi guys!

I´ve made a little brake modification, which works Plug&Play.
Perhaps it is of interest to you, so I took some photos.

Content:
Here in Europe, the pre-facelift 99-02 Celica GT has a front brake disc diameter of 255mm.
Then we have in Europe the Toyota Avensis (called Avensis T25 with 1AZ-FSE engine) with a
front brake disc diameter of 295mm.

The mounting specifications of the Avensis disc are identical to the Celica disc. 5x100mm circle, 55mm center diameter.
The bigger Avensis brake caliper and the holder fit exactly on the axle leg of the Celica.

The only thing is that the disc brake dust cover must be modified a little bit (bend over a bit so that the disc is not grinding on the disc dust cover).

Now, here are a few pics of my modification:

Here is the difference in size between Avensis vs. Celica:

A first fitting test without pads:

The dust cover must be modified:

It is very close, but it fits:

Here a little video, with the disc in motion

Then I was sandblasting and priming the brake calipers:

Now, I replaced the piston gasket, the dust boots, greased the sliding pins
and painted the calipers:

Then, I build the new brake. All Plug&Play. Here are the final pics:

Here, a few months later, with performance discs:

The brake is working perfectly. Very good braking performance compared to the original brake.
Much better than before, but not too aggressive, it can be regulated well - just perfect!

I hope you liked my little photo story!

Best regards from Germany,
Ben

Very nice

Zero · Jul 22, 2012

I like that it's plug-n-play and that it's a bigger kit overall compared to OEM Celica parts.
Very convenient compared to the ST205 GT-4 brake conversion.

DUDE! CRX_fan I freaking love you man! Your work is seriously some of the best for the Celica community! Please keep it up :thumbup:

Also quick question are the Avensis calipers single or dual piston?

Soo__Fuego · Jul 22, 2012

Nice job.

Quit playing. Nvm, you're serious huh, I'll answer your question with a question.

How many piston(s) do you see in the new caliper?

WOW - thank you, guys, for the compliments :crazy2:

The calipers are single piston! 57mm like the OEM Celica calipers.
But the brake pads are much bigger! :AF:

How about rear brakes? Would the Avensis rears be plug and play?

trdproven · Jul 23, 2012

i dont think i saw it but what method did you use to mod the brake cover, just extend and weld?

CRX_Fan · Jul 24, 2012

I only bent it over a little bit with a plier!

When I look at the specifications of the Avensis and Celica disc, it seems like that its possible!

Here:

Only the hole for the wheel nuts is a little bit bigger!

I only have to knew, if the caliper fits to the axle leg of the Celica...

Really nice work as always, but damn those GT brakes was small compared to the euro GTS =D

Oh yeah....

Our GTS have 275mm brakes. And the GT Facelift 02-05 the same 275mm.
Only our GT Pre-Facelift have brakes, which are smaller than the discs from a Honda Fit (Jazz) :AF:

kaizer_soze · Jul 23, 2012

Again, great idea and work. And the rear interests me too

brianv3ntura · Jul 24, 2012

In4sub. I want...

R911Celica · Jul 25, 2012

Would this work for a gt disc brake conversion?
Parts off non celicas are always cheaper even oem
Well here in Canada I would assume the same with all of you.
Sully in demand haha.

R911Celica · Jul 25, 2012

Euro gt's have rear disk?
Or am I correct to assume his car is a GTS?

CRX_Fan · Jul 25, 2012

Hi 911!

My Celica is also only a GT 1ZZ

So it works perfect!

To the rear brakes:
In Germany all Celicas have disc brakes on the rear! GT and GTS.
(I think its because of the fact, that we have no speed limits on german Highways :gap: )

Regards, Ben

mrfunny107 · Jul 25, 2012

thats sick But will someone find a good 2 pot rear caliper that work!!!!!!!!!!! and not $1000

R911Celica · Jul 25, 2012

Fair enough, I'll be looking into swapping my drums out for this cars rear, and if I can find all the parts swap the front disks too

monkeyb01 · Jul 25, 2012

Holy crap I want. Where can we find those calipers in the united states?

Soo__Fuego · Jul 26, 2012

These are 295mm and stock GTS are 275mm. The size difference is minimal and imo not worth the price and hassle of getting the calipers, rotors and pads to do this. I'd be wiser to save up for a Wilwood upgrade from Fastbrakes.

CRX_Fan · Jul 26, 2012

But I have the smaller 255mm GT brakes. :roflno:

And the difference to the 295mm brakes with the bigger pads is noticeable.

And all parts complete costs about $240

Celica59 · Aug 18, 2012

This is absolutely amazing! Will this work on an 05 GT?

nikmoretto · Aug 20, 2012

looks good

TRD01GT · Aug 21, 2012

Nice find, that's a very clean celica too, I'm getting my parts to go back to stock body, I miss it!

Bitter · Aug 21, 2012

At first I was pretty excited, but then I realized that he had the tiny brakes. 20mm larger diameter isn't too much for us US GTS's, but I am curious about the brake caliper. More pad area is always good, same amount of friction going on but over a larger area means lower pad temps. What US car would use that caliper/bracket and would it bolt on like with his Celica? Let's ask RockAuto and ToyoDIY!

Not having much luck.

If you really want to try something better, see the post from oolineooo that uses brembo calipers from R34 and 320 mm disks. He says he used no spacers and works great.
Currently I am looking for the same setup for the rears checking for R34 parts

DevinPickering · Aug 21, 2012

If the rear caliper and mounting would adapt to a 00 GT with drums (I'm in the US), I would pay GOOD money for the OP to ship me a pair of them.

Great Job Ben...Car looks awesome..Did u change wheels?..I liked the ones u had in those pics..Just drop it a little lower and u will be $$$

Thx!

Yes I change my wheels, now I have these:

Sadly, I cant drop the car lower. Because in germany we dont have good complete suspension kits at first. Only china trash. And secondly the streets in my town are not the best, deep potholes over all - the city council spend the money for other shit. And an other fact is, that we have strong regulations for the lowness of cars! :-( THATS Germany....

Italiano · Aug 21, 2012

Yea those are the wheels I like,I was confused by your signature...dont like those as much...

CRX_Fan · Aug 21, 2012

Correct, these wheels I had the last years:

17"

Italiano · Aug 21, 2012

New wheels much Better...
