Yes. The standard non-radial nissins seem to have this problem. The brakes usually work well but lack feeling and are wooden. I changed mine for a Brembo from a newer -05 R1 and it worked wonders. Lots of feel and power. And much cheaper than buying a full spec brembo master cylinder.

 

My concern is more about the physical effort needed, in other words how much force I need to apply to the lever in order to get the bike stopped before the corner. Bear in mind, this is a track bike and I plan to start racing it at the end of the year.

So did you find that the 05 master cylinder also reduced the amount of force needed to pull the brake lever?

 

Actually no. I would say its probably the same. Its more the feeling of it thats completely different and the power of the brakes that feels incresed. But pulling the lever itself requires more or less the same effort.

I can say though, that I put a CBR1000RR radial master cylinder on my old YZF 750 and that became almost feather light to use. A huge difference in that regard. So perhaps that would be better. I myself preferred the feel of the Brembo.

 

Great, thanks for the input :icon_biggrin:

 

When was the calipers last rebuilt?

 

Calipers are fine, the tech did take a look. Ended up using a 2006 R1 master cylinder. It certainly feels a lot better. Now I just need to get back to the track to see what she stops like

 

That wasn't an answer. If you don't know then assume that it hasn't which means there's 15 years of gunk between the Pistons and body. Do yourself a favor and get them rebuilt. It'll feel even better than just a mc swap.

 

Like I said "the tech did take a look" and he says they are fine and don't need a rebuild. When I say "tech" I mean the guy that works on my bike and he runs on of the top bike workshops in my country.

 

Then wtf are you asking for advice here if you have a famous tech? :lol

 

HA!

Anyway, rebuilding the calipers on mine did the trick for me. It wasn't until I popped the pistons that I saw how bad it was in there.

 

Any thoughts on Brembo RCS 19 MC on a 2000 R1? do track and hard mountain riding. Should i go RCS 15? currently have some crappy brembo definitely not radial.
