Ok umm I think we might be getting of point a bit, I know they maybe illeagal etc etc,.......so's getting rid of my rear fender and having blue number plate lights.

What I'm really asking is how they compare for value. I haven't had much luck getting prices locally and I was hoping someone in the know would give me a hell yeah or a steer clear.

Good value for money imho. Slightly less than US$100 would cost about $136 in aussie beer tickets this is good value.

In performance terms, you will be amazed at the difference , in fact you should also replace your brake fluid with DOT5 ( if not already using it), and bung in some better pads as well.

Take care when using braided lines for the first time, until you get used to the greater effect. Otherwise you could easily lose the front end.....

No, and we head OT even further.

IMHO Don't use DOT5 in a street bike unless you're going to change it often. It's not hydroscopic like DOT4 or DOT5.1 moisture does and will get into the system, but instead of being absorbed by the fluid, it pools then causes corrosion, and will boil at 100C where as if you check the spec for wet DOT4 it's boiling point is still well above 100C.

My $0.02c

ADR only for the road, read into what the others have said the answer to me is clear, BTW if you havta ask then steer clear!
For what it is worth pay the extra, come on ffs- really - would you skimp on something that important, especially on a sportsbike

I thought all hydralic brake fluids were hydroscopic, ie absorbed water ?? I know the DOT 5 stuff I use is synthetic ( and you do need to flush out the old fluid completely when using it ).

BTW the best ever brake fluid dispenser I have used is a large 4-litre 'goon', the same deal as a wine cask - it even uses the same 'tap'. As you use fluid, the bladder simply shrinks, and heh presto, no moisture accumulation works great (probably overkill if you are only working on your own bike.....it would take a *few* brake fluid changes to use it all)

Dot 2, 3, 4 & 5.1 are hygroscopic, dot 5 is silicone based and does not absorb water. (assuming i remember my details correctly)

You remember correctly.

excellent!

Mark i would buy them mate, insurance is unlikely to quible if they are made in Aus or not. I paid @$190 for "Tiggrs" from Stamos. No complaints about them once the dickheads at the local Yameeeehaaa (good prices lousy Mechanics) shop fitted the replacement ones properly. Great mod to any sports bike second only to knobs imho.

So Dot 5.1 is ok but Dot5 aint ?. Also is it worth putting a cooler around the resovior. I love a good techie thread.

... Also is it worth putting a cooler around the resovior. I love a good techie thread.

Do you mean one of those fluffy wrist-band thingys you see on race rigs ?? If you do, these are'nt a cooler, they are required by scrutineering to soak up any excess fluid that may leak out of your master cylinder under heavy braking

Never had a problem with boiling brake fluid under *extreme* conditions....during the 2001 season, the brake system was:

(a) - TZ350 master cylinder (1/2" bore - an 'early' one)
(b) - home-made braided lines - 3/8 Teflon. One line to RH caliper, and then 1 short line from RH to LH caliper (often seen on bikes today),
(c) standard calipers (to meet class specifications), with EBC pads (green? ones from memory) - and DOT5 brake fluid.

this system would regularly pull up the 'behemoth' Z from 240 at the end of Oran Park main straight, with all braking taking place after the kink. It was *breathtaking* , but never failed me once. Braided lines are the biz !!!
