Movie: *Testing* Brake cooling on GTI MK7 (7.5), Second fitted *update*

[fredgroves]

If you can suffer from brake fade on the road then you probably need a speed awareness course and not better brakes ;-)

Lol maybe..

But are not the brakes the first to upgrade?!.

To tune the engine and put on a better chassis you don´t need if you just drive on the streets?!.

1 .Brakes
2 Tires and wheels
3. Chassi
4. Engine

Wrong?!

I think the main point here is - fast road driving is about making progress with a focus on smoothness, reading the road ahead and being safe. Same in a car as on a motorbike. On a  typical B road here in the UK, a fast drive for me in the Peaks involves very little hard braking at all, so brake fade through extreme heat is completely unlikely. Hard and late braking is something racing drivers do as they are either on the throttle or in the brakes, no in-between. So this modification is completely pointless for fast road driving, it may however be appropriate for someone who tracks their car every weekend and has upgraded their brakes and still finds they get brake fade. To put simply, you can't drive hard enough on the public road for brake fade to be an issue in the GTI and if you do, you will soon end up either banned, crashing or dead.

But in that case you don´t need the PP brakes?!. I think one of the good think about the GTI is the handling and the brakes. The power in the GTI you get from a ordinary Volvo today.. 

And not drive on the track with a GTI?!.. Why buy a GTI?!

Did I just bang my head against a brick wall with my last post?!

The GTI is a road car, that's why I drive one. Because I use it to get to work, use it go see clients and use it at weekends for driving around. On the road. If I wanted a car to take on the track, I very much doubt it would be a GTI

No, you're underestimating GTIn, I was amazed that you hung up much more expensive and on paper faster cars . Then I'm going to run with Semi Slicks next time is another story

My friend have a 991 Carrera 4 and that is a litte bit better on track  . But on the Highway it feels like a Golf..

I also have a towbar on my, so this is a complete family car

I found a nice Video, that have the same result as mine!. Think this will save brake pads a lot!

Reading this months VW driver mag the CSS brakes don't like light track work, one owner (& first visits to track) had minor warping & was quoted £1,300 for new discs & pads.....

So got the discs pro lathe cut insitu & new better pads...

HOWEVER it turns out what happened is common on top end Audis also.....the discs have directional internal vanes....but the same disc blank is used for both sides, so one side the vanes rotate in the correct way, the other side they do not!! So on this side the discs get way hotter......& problems...

Very clever VW..NOT....

That didn´t sound so good.. . My worked on a pretty fast track, for probably 30 laps witout any isues. ( 3 push laps, one cooling..)

I think this option is a no brainer then!, if you can save your brakes. This is the cheapest option...

I'll add more info..

Owner or Clubsort S (CSS) had 4500miles road use & one track evening at Bedford autodrome...& did cooling down lap.

Warped front discs was the result

The UK drivers side (your passenger side) appears to be the one with the internal vanes rotating the wrong way as they scoop the air from the outer edge & try force it throught the disc to the hub which is the wrong way...

My ATE 312mm discs have internal vanes (like most vented discs), but NOT directional....so I won't have this problem..
