Brake vent

After 10 minutes on the track I wish I would have gone for it and had the RS4 365mm Disks with the 8 piston callipers,

Or how about these 380mm lush puppies - available from your local stealer as an official retro-fit upgrade - for a mere £7,790 - plus VAT! 









Sorry for the thread hijack!  :embarassed:

but this way I can always blame the brakes when people disappear into the distance.

LOL

i'm rather shocked the Brembo GT discs has only lasted 2 track days! But mind you i've never liked drilled discs due to their protential of "cracking" from the holes.

Those Audi Ceramics are monstrous. But you need 19" wheels for those.

I'll settle for the 345mm set up I'm about to have fitted in next 2 months. Much cheaper and should be fine for the GTI.

Sadly, one of the bigest causes of adverse disc failure is soley down to "user error", such as failing to cool them down properly, or keeping the foot on the brake after a heavy stop. 

But mind you i've never liked drilled discs due to their protential of "cracking" from the holes.

So how come all the "serious" OEMs, such as Porsche, AMG Mercedes, quattro GmbH - and the "quality" aftermarket suppliers, such as Brembo routinely use drilled discs without any probs?    The only drilled discs which are prone to failure from cracking radiating from the drilled holes are cheap crap, which don't have the proper chamfering, nor disc tempering.  Look in MaxPower for examples!

But 19s would look nice on a GTI !!

What, OEM R32/S3/LCR spec ones?  I'll be going down that route shortly.

I'm probably wrong but I thought I read somewhere that it wasn't a good idea to create a differential in temperature in either side of the disc.

What a load of tosh. 

Why, then, do road cars have one side of the disc open, in clear view through the alloys, yet the rear side is covered by the splash shields.  Also, why is it that on road car discs (conventional ones, not ceramics or any aftermarket ones), the outer face is connected to the disc "bell", which bolts to the hub, and creates a very postive path for heat conduction, yet the inner face is not, and therefore has no path for heat conduction! 

....Steady on, mate - I did say I was probably wrong and it wasn't me spouting the load of tosh.

Thanks for the rest of your post though - It confirms a few things

Yes TT, I was gonna mention Porsche and some serious top end manufacturers manage to make drilled discs for their cars with no problems re cracking. I think its down to how they drill and when they drill the disc in the process of making it or something. But yeah some cheaper aftermarket ones often crack as they are purely done for cosmetic look reasons (form over function if you will)

Re the 345mm set up:

I've gone for a set off the Leon Cupra, supplied from a Seat dealer, at a stonking price! So still have red calipers.
Was shipped on friday, and should be arriving at my mates tomorrow or tuesday. Then we're gonna do a brake swap (mine onto his car and the 345mm onto mine)

Much cheaper than Brembo/AP's/Alcons and we're saving the fitting cost too.

It should be sufficient for my needs (i do like doing track days too) and cope with the plans i have for the car.

How much did you pay for the lcr brakes chungster?
I bought an r32 front set with 5kmiles on them for £330. Just need to mess about now and get the calipers painted red.
Anyone know if there are any decent aftermarket brake pads that will fit the r32 brake calipers?

Got the whole lot brand new delivered for £550!

Is it me or should TT resize his pics?

I would suggest seperating the calliper from the piston, remove the 4 * bolts pictured below
 
then either clean & spray the calliper or take to powder coaters.heres some pics of mine done, I also coated the calliper clip with heat res silver spray.

Yes TT 100% my fault with the cracked discs, stayed out a few laps to long at Bedford on pads that had seen better days and didn't cool them down properly, an expensive morning.
I'm after Brembo drilled disc replacements for the rear but their seems to be a problem with the main importers going bust I think.
