Ok,
I've heard that the V6 brakes are bigger, but have also heard they use the same brake pads :nuts: , so i'm really confused. So if the V6 brakes are bigger:
I have a 4 cylinder, i wanna know if the V6 brakes will fit my car without any trouble (just a straight swap). I'm talking about the rotors etc. everything i'd need.

From my undestanding it is the abs pack that brings bigger/better brakes, as you get twin piston front calipers and vented rear discs
Hope this helps

Here's a bit more detail.
TR,TS 4cyl (Excuding Elite) Front 256mm vented. TR, TS 4 Cyl + V6 Non ABS Rear 251mm solids. TR TS 4cyl Elite and all V6s Front 276mm vented. ABS also run a twin pot caliper on the front. ABS V6 Sedan rear 266mm vented. ABS V6 Wagon Rear 284mm vented

That's good to hear, so in theory with V6 brakes on my 4 cylinder, they'll be better? So what would i need to convert my brakes to V6 brakes instead of the 4 cylinder ones? thanks.

I would say fromm what philsTH has said you would need everything from the non abs V6. front disks, pads and calipers. rear disks, pads and calipers and the master cylinder and vacuum booster if it's different

Seriously though, why bother? you plan on reachin that high speeds to waste your money on something thats about 5% better?

I'm with Gerard here, the standard 4cyl brakes are sufficient for the weight. I drive some pretty step and long hills that will easily overheat the brakes in most cars. A 4cyl TR magna is about the same as a VL Turbo for brake life before overheating and for brake performance at high speeds, both were driven with Asbestos pads.
Brake fade isn't an issue in 4cyl TR/S Magnas unless your trying to go down 6km long 30deg declines like I do.

all i can say is that i have the abs v6 wagon brakes and have changed the front to cross drill and ventilated disk and it will stop on a dime , my 2 censt
i would say that you could change the parts , i would recomend bying the crossed drill front disks they should be able to fit straight on , and i think the twin calipor one should go straight on , you may not need to change the master cylinder

norm

Well no offence at all to tr-envy, but Nicem8 your car is pretty much classified as a show car. So having upgraded brakes including cross drilled and ventilated are something you'd find on a show car.

Unless your planning to make your car look mean (with crossed drilled which look niice) OR you have a fast car that requires better braking system. Or drive regularly in areas that require constant braking etc... having V6 brakes is really.. unessecary :)

But hey, If its cheap and your really up for the idea, it couldnt hurt.


On the topic of brakes:
Did you know some people actually drill in their own holes/slots into the rotors. As a cheapo home job for upgraded brakes :nuts:
how dangerous is that, risk of cracking etc

The best value for money upgrade for the 4cyl is to fit slotted rotors and some good pads all round. I have DBA slots and QFM Comp3(track) pads on the TS and how hard it brakes scares most people. Drawbacks with the pads are the brake dust, bit noisy when cold and that they only last a max 20,000 kms, but it stops awesome!

As above, slotteds will get rid of brake fade. As for master cylinder/booster? will find out bore sizes .

Not sure wether this would work or not, but I know that the 2nd gen shares the same bolt pattern and AFAIK the same offset as the 3rd gens.

"IF" this is the same then "maybe" the 3rd gen brakes may be interchangeable with the 2nd gens brakes??? By default the 3rd gen runs 278mmm rotors upfront with a single spot caliper which would still be better than an upgraded 2nd gen brake setup.

As stated, not totally sure if this would work, but might be worth considering as a budget idea, especially if you got at a wrecked 3rd gen somewhere? :confused:

It's funny I was having this conversation with a group of guys, one of whom was responsible for the TR's brakes. He now works for a F1 team. The jist was that he felt they "were'nt my best effort".

Personally I don't agree. Add some GOOD pads (Bendix advance at least) and some DBA rotors (slotted if you need them) and get the fulids changed.

Makes the world of difference.

I just ask because they have been fading and overheating, not alot, only when i'm going down hills or around twistys, which i dont often do, but when i do i just wanted to know if the V6 brakes will last longer. Also with stop start driving all around city when i go cruising they can get fairly overheated, i've heard from a couple of 4 cylinder TR drivers that it's a problem.

The 3rd gen fronts are exactly the same as a TR, the rears, however aren't. They're deeper in the handbrake drum hub bit thingo lol

And the pads are the same, I have SARRAS's stock TJ front brakes on my TR right now.

With the setup on my TS they won't fade driving hard down down the twisty bits(eg. Maqurie pass) but the pads don't last long so it can get exspensive. I'm pretty sure the V6 callipers run bigger pads so they may last longer.

If you want to go through the trouble of upgrading the calipers consider something like the Ralliart upgraded fronts from somewhere like RPW. Or if ya wanna go crazy talk to tooSlow about getting something like his Brembos(now they are awesome!!!).

It all comes down to the $$$ you wanna tip into the car.

On the way to tafe today they faded very quickly (on the highway in not even peak hour stop start traffic!) I hardly used them at all! Had to use the hand brake :(. Could there be anything wrong that causes brakes to overheat? back pads are fairly new and the fronts got done about 3 weeks ago.

Sounds like **** pads to me, the first time i had the pads changed in mine i had the same experience. Did you let the pads bed in for a while? Sometimes that can make a difference. What pads did they use?

Ok, as I have done these conversions I can tell you guys exactly what fits what on a second gen

First of all, the v6 rotors will bolt straight on, the backing dust plate needs a little "tweak" at the top, about 3mm push back and that is it.

The V6 and 4cyl caliper is identical as is the single pot third gen. It is the bracket that is different to allow for the larget v6 rotor.

On Lethals car, we fitted V6 lower control arms, Slotted V6 rotors and twin pot abs calipers. The brake hose is slightly different, all you need to do is ge ABS to make new lower sections to cater for the different fitting.

The Booster and Master cylinder is the same on both 4 & 6

For the "why bother"s here, when driving our cars hard through the spurs or anywhere else for that matter, you need all you can get to avoid brake fade.

KB has been in my car and knows what the car stops like with the twin fronts, it is un believeable. Driving skill has a lot to do with brake fade and over heating, as a few of the vic boys have found out of vic cruises in the past.

I'll vouch for that stopping power, I drove it...**** it was awesome.

Hence why Im doing the same thing.

perhaps I should change my sig to "Fastest stopping 2nd Gen in OZ lol"
