"BIG Brake" Upgrade

Hi everyone,
So, my discs and pads called for a replacement and i decided to go a little bigger, the money difference being not that huge.
I started with the back, from 330mm i went to 358mm and to reposition and fit the calipers i used some stainless steel spacers, locally made, and some longer bolts from Panamera and Cayenne i believe. I also painted the dust shilelds using some hi temp spray. Next i will powdercoat the calipers.



Then, i proceded with the fronts, from 330mm discs i went to 350mm and sourced some 18Z brake calipers which were in a very good shape but poorly spray painted. I powder coated them, new Brembo logo and then powder
coated again with a clear coat.



In the end, i bleeded the sistem using ATE SL.6 brake fluid.
I didnt't had time to properly bed them yet but i dont expect a huge improvement over stock, stock being more that anyone could ask for, but better cooling, maybe a better pedal feel and "the most important", visual (+50 Hp, because they are red :D ). After a few hundrets Km, i will update this thread.

Looks like a well done conversion. Whats the diameter of your rim and how's the clearance And assuming you kept the same master cylinder, do you notice a difference in pedal travel

Have you uprated the brake hoses?

If not, you should.

The rims are 20 inches. The clearance is tight, around 5-7mm, but i know for sure that using stock wheels clearance is not an issue. Pedal is still "soft", i think i may have some air trapped and i will adress that issue soon.
Stock calipers:


Brembo 18Z calipers:

Thanks for the ideea, now i'm planning to upgrade them with HEL VW-4-460. I've heard stainless steel hoses makes a big difference.

I assume that fitting the 18Z's you went from 4 spot to 6 spot (pistons).

Have you thought about the need to change the brake module coding to tell the vehicle you are now running a different brake set to what your Touareg was factory coded for as your braking efficiency would be different now to the original?

@groundskeeperwilly , I've seen your topic here and youtube video a while back. Nice color :)
@seafarer28 , yes, from 4 to 6. I haven't really tested it yet but as far as i read, many people coded the brake module and many didn't. Those who did eventualy returned to stock coding. For now i'll stick to stock coding.
Over here, I am cheaping out on buying legit OEM replacements.... you guys are just throwing your money away on "upgrades"...... maybe I need to immigrate "back". :eek:

"Legit?" The 18z's were fitted to the V10. And no, no need to re-code.

Yes, I run el cheapo parts.... not even OEM... this is CAD

.... and you guys don't have V10s so I'm not sure why you're mentioning that..... are you suggesting the V10s could outbrake the rest of us? :unsure:

Hmmmm. Too bad you weren't in the room with the Porsche/VW engineers when they were designing the braking system for the Touareg and Cayenne. "Hey guys, we don't need those fancy 6pot calipers and larger rotors. It's all for show anyway. Look at this cheap crap we can buy from Canada. Think of all the money we'll save!"

But hey, if mediocrity is your thing, who am I to criticize?
Too bad you don't spend any time reading the many available tech, engineering, physics, economics, marketing articles that are available for free instead of choosing to be a sheep.....

Just think of the knowledge you could absorb to understand physics, heat dissipation, friction, etc....

I'll keep driving without brakes over here because I didn't spend a few $K on better parts.

But the improved performance!!!!!!!!……

I like them..Plan to do this myself eventually and for no practical reason at all. 6 piston calipers look cool and are worth all the street cred😎

Take your OEM setup and stand on the brakes from whatever speed you typically need to slow down from.... If your wheels lock up or ABS kicks in, spend your coin on wider, sticker tires.... When you can no longer lock up, start upgrading your binders and rotors...

For cool points, I'd do Urus brakes. Hard to beat those!

That Urus is a bad mofo! And based on the same platform as the Touareg/Cayenne/Q7.

Hi @SaVAGeSoot,
Anyway i needed to replace the front/rear rotors and pads and the rotors were 40 Euros more, per set, and the pads around 25 Euros more. I also had a 40% discount on parts. For the calipers i paid ~200Eur, 80 Eur powder coating and the labour was done by myself.
At first i wanted Brembo 19Z (newer Cayenne) and 368mm rotors, but the whole setup was too heavy, too much unsprung weight.
Immigrate back? :D Where were you born? If its somewhere around Central/Eastern Europe you already know we have cheap prices, good beer and pretty girls.
Cheers 🍻
Born in Bucuresti.... raised in Bucuresti & Constanta.... came over here in '90 after Ceausescu got it....... I know all about your hood ;)

For anyone who's "on the fence" about Big Brake Kits for "gains", here's some entertainment. (once again, if you're doing it for looks or because you can, or because you have a track Touareg, this doesn't apply to you.... @volkswagens-for-life )
