Hi everyone,
I am looking to improve the little gixxer's brakes. I have flushed and replaced brake fluid, new HH pads and have new-ish rotors but no significant improvement in brake performance.
Any ideas for improvement? Is this a known complaint with older GSXR'S?
Is a Brembo or other master cylinder a worthwhile performance upgrade?
Thanks in advance for the help.
Did the bike ever have the brake master recall done? IF not, nothing is going to help until it is replaced.
Hmmm, not sure and didn't know there was a recall on them. Thanks.Quote:

Look for the two circled areas in the results.

Throw in some new steel braided lines too. That with the MC should help.
Like Steve said, recall your MC, and then like Dirk said, throw in some SS braided lines. My experience with my 07 gixxer was that these things will help a bit but as you go faster and brake harder and harder, you will eventually want a better MC (Brembo, Acossatto, etc). Then well, if you know you will keep the bike, you might just as well save you some time (and pain) and get yourself a decent MC for Christmas :).
And different than what many told me when I was going through the same pain you are now, the calipers can be part of the problem too - I felt a big difference once I rebuilt my calipers too - Never needed to change rotors though - The OEM rotors are just fine.
Thanks Steven, Dirk and Marcelo. I do have SS lines on it and appreciate the additional insight. I checked the VIN on the recall site and confirmed it has not been addressed.
Now I have to decide if I just go straight to an upgrade or have the MC fixed through Suzuki. I'll definitely go through the calipers and clean them up too.
Have Suzuki replace the MC first (they will replace it -this is what the recall is about) - But start saving some $$ for the new MC anyway - it's on your future :)Quote:

The new OEM MC is no better than the old version. I have 2 K5 750's, one street, one track. Had the recall done on track bike and it didn't really make a difference. Finally upgraded to Brembo MC and its much better with SS lines and OEM rotors and calipers.
True, the new MC won't perform better unless your old one is already presenting the very same issue the recall is supposed to address. My advice would still be do the recall before anything else, however as I said, the after market MC is on his future regardless.Quote:

If you don't want the recall master, you can go ahead and do it, then give it to me when you put the Brembo (or whichever) on. ;)
Make sure you are using a good fluid that won't boil so quickly like the OEM.
I think most of us are using the Motul 660 which is a High Performance brake fluid with very high dry boiling point of 617°F (325°C) and wet boiling point of 400°F (204°C). For all types of hydraulic brake and clutch... just saying...
Here is the comparison between the 600 and 660 "RBF 660 Factory Line features a dry boiling point of 325°C, higher than RBF 600 Factory Line. ... It maintains a higher dry and wet boiling point of 272°C and 185°C respectively compared to DOT3&4 and DOT 4 brake fluids.
That's a very good point! I had assumed that was cleared already, but I shouldn't assume anything :)Quote:

Getting MC rebuilt under recall this weekend as Steve said and will decide if I go aftermarket once I have a chance to compare.
