Look at your Master cyclinder on the front part where the word Nissin is molded in-
just before the brake line bolts up-there is a number there- on my early '06 Speed Triple it is 4 Nisssin.

On my son's later '06 Sprint STS it is 6 Nissin.

The latest 06 Speedy and the new '07 (Green) Speedy on the dealer's floor is is 8 Nissin.

These numbers are molded in the metal just in front of the word Nissin.
Wonder what they mean?
My brakes '4' are mushy s*****.

My son's brakes "6" are ABS and are less mushy but need pumping up every day.

The new bikes on the floor are "8" and the lever pulls are ROCK SOLID. Feel great!
How do we get the "8" brake master cylinder?? Is that the answer? Looks like it to me.

Our 06 demo has a 6 on the master and have had no probs at all. BTW, comparing S3 brakes with the ST is not much use as the calipers are different.

Early 06 here... 4 with mush. I wonder how hard it would be to get somebody at Nissin to let us in on the numbering scheme in order to determine if this is merely coincidental or whether there are material differences in the versions. I'll see if I can make some headway in this area.

I have a "5". My brakes are about in the middle, not real mushy but don't grab right away either.

I suspect it is just a casting cavity number. Most tools for injection molding and die casting have a cavity number on them so that the quality and maintenance technicians can track defective parts back to the tool that produced them.

That is what I assumed and asked for clarification of that specifically. Additionally, I went to the local Trumpy shop today and the brand spanking new S3 had same casting number as mine (4) but a heap more resistance. Of course, it hasn't been flogged by me for a year either...

It will be interesting to see if they respond. If so, I'll ping them on the sticky bits in the calipers to see if they can shed some light on it.

Hivel, do you have a banjo at your Master Cylinder with a bleeder built-in? I'm thinking if you bleed your lines at the top you'll have a lot less mush and both your son's and your brakes won't need pumping up nearly as much. My GSXR MC has the bleeder built into the MC and it works great. Only a minimal amount of mush and I can bleed the bubbles off with just a baby bottle, an 8mm wrench, and a piece of hose in a few minutes.

I have not found a place to purchase the banjo with the bleeder built in-do you know who has this available?
