I've bit the bullet and gone and got myself a 5/8 (16mm) Master Cylinder. I was off a Kwaka ZX9 (98), cost me $60 Aus.

What can i say... The brake feel is 10x better than standard. No matter how hard i try i can not pull the lever in more than 1/3 the way. I love it

If you want to fix the soft feel of your brake lever then go get yourself a 5/8 Nissin master cylinder. You will not regret it.

Thanks Sparti!! :-D Just what i wanted to hear.Had this discussion at the dealer a bit ago.I guess any Nissin 5/8/16mm would do the trick.CBR,RC51,etc. THANKS!!

If it is the same 5/8 Nissin Jack Lilley sells, it looks identical to the stock one. It only has a larger bore and is a direct swap with the stocker. All bolts, brake light switch and lever will work.

The only discernable difference is that it has a 5/8 stamped on it.

Skyking has this:

I ended up getting a radial mount off a GSXR K5 for $100. It's a Nissin so the cap (has the mirror bracket) bolted right on. Only problem is it hits the faring when cocked right. Feels much better but havent had a chance to road test it.

That Skyking kit is what I bought.

I just did the "pushing in the caliper pistons" trick (suggested elsewhere on this forum) and I was shocked at the difference it made. Brake feels awesome now. They reckon this trick only lasts a few weeks though before the problem reappears.

Most people have deduced from this that the problem lies with the caliper seals and it seems as though some dealers are rebuilding calipers as a permanent fix.

It seems interesting to me then that some people are claiming a new master cylinder solves the problem. I seem to remember reading about someone a fair while back that tried a new m/c with only mixed results. Can anyone confirm the problem is still 100% fixed a month or more after having only replaced the m/c? Sparti, can you please report back after 3-4 weeks.

If this is really a m/c problem and not a caliper problem then all I can think of is that perhaps the action of forcing fluid back into the m/c by pushing back the caliper pistons somehow gets the m/c working properly again...temporarily at least.

It's definitely not the size of the m/c that's the problem here as I have just proved with my little piston pushing excercise. It must be an issue with the mechanicals of the particular m/c fitted to the S3.

Sure thing.

FYI though - If you want a longer term evaluation of the 5/8 M/C just ask kuhlka. I believe he's had one on his bike for a number of months now.

Thanks Sparti. Kuhlka has an 03 S3 and from what I've read he's done a lot of mods to his brakes. I'd like to hear from someone with an 05/06 that has only changed the m/c.
