Brake upgrades (RS4)

Thanks TT!
So, I should stick with the genuine VW brake fluid. :sad1:
If I was to consider a higher boiling point fluid - what would you recommend. Ideally something VW approved and does not mess up the ABS/ESP units.
Cheers once again... :happy2:

You will ruin your ABS/ESP unit - and get a nasty bill for £1500. Flush it out and put the proper spec VW fluid in.

Hi TT,
Are you saying that we should stick with VW spec brake fluid. I was thinking about putting dot 4.1 oil (or something like that).
Please provide a detailed run through...
Thanks in advance. :jumpmove:

No problem whatsoever putting in Motul RB600F fluid.

Huh, how can you say that? That fluid does NOT comply with the required VW standard! Or are you going to cough up everyone elses bills when it toasts their ESP unit? :stupid:

I've used this in all of my high performance and track car's in the past and currently run this in my Ed30 which has seen a full monty use at Combe in July. Works very well in conjunction with EBC Yellow's too!!

I'm NOT doubting its 'motorsport' credentials! However, I bet that 99.9% of all 'big brake' or brake upgraders on this forum still use their car on the road, and still have the OEM ABS/ESP unit fitted. But the Motul RBF is specifically designed for motorsport applications, where ABS/ESP is banned - so the viscosity is not an issue. Furthermore, the Motul RBF isn't that much better than the standard VW OEM fluid, which itself is an exceedingly high quality fluid, and out performs many 'so-called' 5.1 fluids
Motul RBF 600: wet boil: 216degC
VW fluid: wet boil: 172degC - which is way better than many specialist products, including Mintex, Vavloline, AP Racing (at a shocking 151degC)
But if you genuinely want a top notch motorsport fluid, then you really should be using Castrol SRF, which has a stonking 270degC wet boil. :wink:

Is that without VAT?
Are they a 2 piece set up?
Seems very cheap :confused:

Huh, you lost me on that?

Never had an issue with Motul RB600F...more than capable over the OE stuff.
Most of the people I know racing in the National Windcreen champ are using it and is used elsewhere in Msport.
Certainly a viable upgrade that won't harm your braking efficiency.

Just stick with VW fluid. Like I said, the VW fluid out-performs many of the so called high performance fluids. Don't forget, it is good enough in my RS4 with ceramic brakes, or the mighty 2½ tonne RS6, or the even mightyer Bugatti Veyron! :P

The issue with RBF isn't anything to do with it being 'capable' or not, nor is it questioned about it's motorsport credentials. What is very highly questionable - is simply that it will fcuk up the ESP unit! Hence why I keep batting on about road cars - with their 'delicate' ESP units, which must ONLY be fed with genuine VW fluid. :indifferent:

I've run Motul RB600F in my previous MKIV,RS4,VR6, MK2 16v Slick 50 race car....never an issue on the ESP and it's certainly of a the adequate viscosity to be reliable.
Mr Brockbank over at Badger 5 on Seatcupra net also swears by it. We've both been around the track and race scene for years and used it with good effect. I take it that the VW fluid has been upgraded in the last few years as the old VW fluid was a DOT 4 then went 5.1
As you comment SRF does the biz and retails for alot more but you can't discount Motul.
