Hi all, just got back from weekend trip to the ring. Been a few times but first time in the rs6.
Really good time exept when i managed to boil the brake fluid and lost all brakes for the last few corners!! scary but luckely managed to keep it on track. think i was i bit heavy on brakes.
Anybody using uprated brake fluid in there cars? other than price whats the disadvantges of using race brake fluid?

Hi Gig

Ive recently come back from there too.

A trip like that makes you fall in love with the 6 all over again

I use ATE Super blue on mine, and just before i went i changed the front pads as well.
I had no problems what so ever and i have even used pads from euro car parts which were only £100 and i can vouch that they are as good as OEM's.

Im also looking at goodridge braded lines as well to give the pedal a bit more of a feel.
I dont track the 6 in the UK, i just visit the ring once a year so can i justify braided lines................I think any enthusiast would

I think there has been some discussion about super blue on here recently so it may be a good idea to do a quick search.

Cheers

I now use ATE Super Blue (racing brake fluid) along with the Phaeton brake cooling ducts. I learnt the had way after boiling my fluid at Mallory.

The stock pads aren't really up to heavy track abuse however. Also depends on how long it's been in the system of course, flush before tracking and you should be fine.

ATE Super is £16 a litre, so no where near as expensive as Castrol SRF (£50). I would flush the ATE every 2 years (at the least) and before every track session, SRF requires more frequent changes

How many laps can a standard 6 manage before overheating the brakes/fluid and such?

[jd_hants]

This may seem a thick question but when you say flush do you mean bleed each brake in turn until the new fluid comes through or is there more to it??? Is 1 Litre enough for the whole system?

[bazza]

If its the ring then 1 lap at a time. As for shorter tracks..........maybe Grant could comment but i think it would depend on the track.

I managed 5 laps round Mallory (1.35 miles each) stock, with OEM fluid in it. Truth is I didn't know when the fluid had been changed , but the pads were smoking anyway. I was a track newbie.

I did 8 laps round the GT circuit of Bedford (3.7miles each) without any fade or boiling (with cooling ducts and ATE fluid). All in all I went out 5 times in a pm session with no problems other than needing something like DS2500 pads (and more petrol!). I also decided to do another flush when I got back from Bedford and checked the brakes thoroughly.

When I first did the fluid change I bought 2 litres and only used 1. The super blue is good (in that it is blue!) so you can see when the fresh fluid gets to the calipers.

As for the flush itself I get as much of the old fluid out of the reservoir first, then attach the container/pump and bleed each brake in the usual sequence.

Actually, I felt that the PS2s were too hard for track use... I will be trying different rubber when they are up for replacement.

[Gig_Georg]

Sounds like ATE blue is the way forward. I cooked the fluid after only 2 laps on ring, with a 5 min break between the two.I did have 4 people in car for first lap, soa lot of weight to slow down.
I'm using ferrodo track pads(ds..something ) they seem fine, std discs nicely cooked but also fine.

I use ATe Sb too, its the nuts, I have the u20 BB upgrade and ducts, and I have had no issues with stopping whatsoever, even after "moochie driving".......

[paulm846]

when i did a ring trip in my last rs6 i did the 1 lap and the heat expanded the fluid so much it boiled over and promptly set alight. no fire extinguishers handy so a bottle of fanta (orange) did the trick
moral of story, after each lap go for a short calm drive to cool the brakes and a fire extinguisher is handy also

[stumpyrs4]

You know when you've been tango'd...

[Cornishmoocher]

This was after some moochie driving, as you can see, they still work ok..... http://www.youtube.com/watch?v=dIh32Jhpy2w
