Ok guys, I have had quite a bit of brake issues recently. Not only do I constantly have air in my lines it seems, making the brakes squishy, I had terrible brake fade at my last trackday @ VIR. I just dont think I have near the feel or stopping power I should be getting. It might just be due to air in the lines though. I have upgraded to SS lines, EBC HH pads, cleaned my calipers, replaced the seals, and bled the lines multiple times. So here I am, considering putting a GSXR master cylinder on my 2nd Gen sv650. I have tried to do my research, but I am still a bit hazy on some of the details.

Here are my previous issues threads:

Ok now for the questionings:

1) Can I use my SV Spiegler lines and MC banjo bolt on the GSXR MC, or do I need to get a diff MC banjo bolt and 90* bent banjos

2) What year GSXR MC should I get? From what I read a 06+ GSXR 600 or 750 works best

3) The GSXR MC will fit on my stock sv650 clip-ons, right?

4) Honestly, is this upgrade worth it? Is it too much stopping power for a SV? What if I just got this MC banjo bolt with a bleeder on it from SVRacing Parts instead of completely upgrading the master cylinder?-->http://www.svracingparts.com/products/#ecwid:category=589029&mode=category&offset=0&sort=normal It might take care of my air issue and get my stopping power where it should be.

Any other thoughts, input, details I should know are welcome! Thanks guys! :eek:ccasion14:

-Oh, and I am also replacing my crush washers just in case from here-->http://stores.sportbiketrackgear.com/Detail.bok?no=15602

A year or two ago I was running a GSXR radial with stock SV calipers.

1. I used the thing Sath posted. Works good. The 90 degree mounting difference makes something like that necessary.

2. I think mine is off of a 08 GSXR 600. I'm pretty sure all of the newer ones are 19mm or something but I can't remember for sure. They are a larger bore than the SV and will result in less lever travel.

3. Probably. I was running clipons so I don't know if the stock bars are long enough to fit everything...but I think so.

4. It wasn't a huge difference, but it was an improvement. It's good enough that I have no intention of upgrading to a brembo.

A couple other things...The extra bleeder built into the stock GSXR master is a nice feature and makes a bleeder banjo unnecessary. Also, in case you wondered, the stock brake switch wires will plug right into the GSXR master.

awesome. great input, thanks ineedanap. i think it will be worth it considering just the banjo bolt would cost $20, and getting the gsxr master setup would run approx $70.

Oh and one more question. If I get SS lines for a GSXR MC, but have stock SV calipers, can I just buy GSXR SS lines and the banjos will fit at the sv caliper end? Or do i need custom lines that have GSXR banjos at MC end and SV banjos at caliper end?

I dunno. Not sure what length the stock GSXR stuff is. When I had mine I had regular length Galfer SV650S stainless lines with the HEL 90 degree adapter. It fit fine.

my issue is that the SS lines I currently have are, for whatever reason, too short it seems. The lines are almost, but not quite taut with no weight on the bike. It only became that way after I had GSXR internals thrown in the forks which might have extended the forks a bit? Idk. They were perfectly fine before the fork upgrade. So im a little skeptical using the SS lines I currently have. I mean they work, but just seem 1 inch or so too short. Its weird.

I guess if nothing else, buy the MC and the add on piece to use stock lines and see if it works. $13 bucks is much better than $100. LOL. But then again I dont really wanna cut any corners and get screwed over. haha. I hate it when stuff doesnt work out the right way the first time

The original banjos should work just fine.
There are only two common sizes, and all of the Japanese manufacturers use M10x1.25 banjo bolts.

I was under the impression the stock SV brake calipers were not to great to begin with (2 piston). I would also say the EBC HH pads are terrible compared to many other options (Vesrah, EBC Extreme, etc).

Make sure you are bleeding the brakes completely. It usually takes me a full bottle to do the front end of my GSXR. I have to replace the teflon tape on some of the bleeders every once in a while as I was getting air through one of them.

Stock sv calipers are sufficient enough to stop a SV on a dime. I'm wanting the gsxr master for more feel, adjustability, and better bleeding (stock SV doesn't have a MC bleeder nipple).

I ended up going with a 2011 gsxr 750 MC, Galfer SS lines w/ 90* bend, and putting speed bleeders on. Might get some versah pads, but they aren't cheap. Might just stick with the ebc for now.

I honestly would say the EBC's are utter garbage for racing/TD. Better pads are more $$ but you really really notice it above everything else I think.

The HH's (mine and many others) get glazed or heat soaked so quickly you lose all feel with low track useage. You don't have to get the $$ Vesrah or whatever race pads. I think even the Carbon Lorainne (SP?) or basically anything other than the HH would be better.

Hmmm. might look into that then. Because I did indeed lose a lot of feel my last track day. Especially on my last session out. Seemed like I kept squeezing the lever and it just wouldnt bite!

Ended up going with a 2011 GSXR 750 master cylinder, new Galfer SS lines, RBF 600 fluid, and speed bleeders. The lever is much more firm now and the brakes seem to "bite" harder. The new MC is going to take some getting used to until I find what setting works best for me. Overall it was a great upgrade and I recommend it to anyone!
