    I wonder if the fluid could be run through a vacuum chamber to "boil" the water vapour off? May need to be warmer than room temperature to work though - just a random thought.
    The brake system isn't actually closed - even when you put the lid on the reservoir, it's not perfectly sealed, and water starts to get into the system.

    The same goes for open bottles of brake fluid - they gradually absorb water into the fluid as well. Always use fresh (sealed) fluid, once the seal inside the lid is broken, the brake fluid is starting to absorb moisture.

    oh im sorry my mate. how many bathurst races have you won again?

    i think it might be called brake modulation.. u press and ease on the release as you enter the turn.. but you sound like the expert please let us know... it would really be foolish to think that guys with actual track experiences with certain equipment might actually know waht they are talking about .... or brake specialists know anything about how pads and calipers perform on the track.. couldnt be a possibility on VW WATERCOOLED FORUM feat lucas_GTI and OSZKO

    Maybe we need to ask Manaz i think hes in a position to make give us a lesson on how to modulate your braking around a track or what the best techniques are.

    Definately didnt expect it to be same as pottering around the city in traffic ... but you let me know OSZKO you sound like you know the best

    As many as you have no doubt. How do the Kinforests perform on the track by the way?

    Like almost all regular road tyres I imagine - they'll get too warm too quickly and will lose all grip and will shed rubber like it's going out of fashion. Even "sporty" tyres like RE003s don't do well on the track. I've done track days on road tyres, you really have to spend time getting them up to temp slowly (1-2 warm-up laps), then a hot lap, then immediate cool-down laps. Otherwise not only does performance at the track suffer, but lifespan suffers if you get significant heat cycles into them.

    Road-legal R-Comps are MUCH better, and can be surprisingly affordable, as can second hand tyres from places like the AE86 series drivers who turn their tyres over regularly, and you can easily get a good couple of track days out of tyres from them). I've found it's best to have separate track and road wheel/tyre combos - carry the track wheels/tyres to the track, change them when you get there, change off them back to the road set when you finish - also handy if something goes wrong and you damage a wheel/tyre to have a set to drive home on...

    EDIT by Manaz: Cut out some extraneous stuff, added some more detail.

    Depends entirely on the pads. Like tyres (as per my previous post), regular road pads get too hot too quickly and the binding agents in the pad break down and they stop gripping and you just chew the **** out of them (even worse on slotted rotors). The "solution" is pads designed for higher temperatures - but the compromise then is that such pads generally don't perform well when cold - something to be aware of on the drive to/from the circuit (if that's how you get your car to/from the circuit - I'd love to be able to trailer the car I use for track days, but I'm not set up for that).

    Quite a few people actually change pads before and after track sessions. Even then, you need to spend 2-3 laps getting the pads up to temp if you do that (and if you're running r-comp or better tyres, getting them up to temp as well).

    Good pads chew rotors too though - it's one of the reasons many people with dedicated track cars (or road cars that they track regularly) run two-piece rotors - replacement rings are generally cheaper than full rotors (and you get other benefits such as lower unsprung mass, less heat transfer into wheel hubs, etc). Be careful doing track days on drilled rotors - drilling doesn't actually help with much (slotted rotors are better in terms of degassing), and drilled spots are weak spots for cracking (more likely if you're doing track days as the heat cycles are more extreme).

    The 380mm stage 3 brakes fit like a glove!

    The 20" Rosario wheels provide plenty of clearance, though you'd probably want to measure/check before going with the 345/355mm options (the 345mm Stage 2 Racingline template didn't fit).

    Harding Performance did me a great deal on some ex-demo stock (from Golf GTI with ~1,500kms) - they even kindly agreed to take some photos during the install for me =)

    So far, they are driving great. No rattles or squeaks, very smooth and responsive braking. They don't have wear sensors, so this has been disabled. I haven't tested them properly yet as I had the old calipers/rotors in the back - but will report back once I do.

    It seems I now have some "unpainted golf R" brakes to sell.

    I'd rather not disclose as it was a one-off deal (ex-demo stock) - HP may be willing to tell you if you contact them directly.

    I was looking at $1,500 for standard OEM replacements anyway and I now have the old calipers etc to sell - which also helps the equation a bit.
