08 and 09 Brake Master Cylinders???

Hey folks,

I just wanted to ask if anyone with the 09 versys has noticed a difference with the updated front brake master cylinder unit.

I have put stainless lines on my 08 both of which run straight from the master to the calipers. I have bled the hell out of it several times. Ride, bleed, ride bleed, etc and still spongey. I had stainless lines on my old bandit 1200 and those were MUCH firmer than this. It makes me wonder if the 08 Versys Master cyls actually displaced too little fluid for the two calipers. The 09's look a little longer and may be a little better. I squeezed the levers of a coulpe 09 Versys (Versi?) in showrooms and it feel better than my 08 with lines and relentless bleeding.

Can anyone confirm this? I'm thinking they must have changed the master cyliner unit for some reason ?

Thanks!

I can't confirm it, but I can say the 09 frt brakes are "just ok" stock. teflon lines made them feel much better. I use a single line w/a crossover. have you tried banging on the calipers/cyl w/ a piece of wood while bleeding to dislodge any sneaky bubbles of air?

They are definitely different master cylinders. The chamber is shaped differently, the 09 has a pushrod and the lever is different. The calipers are the same. Installing SS lines made the brakes on my 08 much firmer.

Sounds like a challenge to me!

I'm with CrazyCarl. I installed Gafer SS lines, speed bleeders, and fresh Castrol GT LMA synthetic brake fluid two weeks ago. While it is much better, it's nowhere near what I want. Aside from a Brembo radial master, I would love to see what the piston size on the OEM 09 Versys is for a possible upgrade. That and DP brake pads....

I'd be willing to try the change and see how it goes. Question is, will the master cylinder from the 650R work? Hmmmmm....

I had a bad master cylinder on my Gixxer and I could never get a firm lever. Perhaps you could find a performance shop to bleed it? If they can't get it firm either, I'd try another m/c.

Isn't that kind of like asking someone else to cook your meat at your own BBQ?

For the price of asking a shop to do it for me I could go ahead and try a new m/cyl and report the findings. Worse comes to worse, I install the old one and live with the brakes the way they are, which isn't bad but I'm just picky.

After a little bit of research it looks like there are a couple bikes out there which use the same type of caliper. The older Bandit 600/1200's, VStrom DL650/1000 and of course the ER6 and Ninja 650R.

If anyone out there has any direct experience with these models and/or can help me confirm the caliper match... it would be GREATLY appreciated.

I had the same problem when I replaced my front brake levers and master cylinder with Beringer units. (Hated the stockers) I had to resort to using a turkey baster. I filled the baster with brake fluid and attached a rubber hose between the tip and the bleeder value. Pushing the baster plunger in slowly pushes fluid from the baster UP into the master cylinder. This method always works for me.

I never realized how handy turkey basters are...brake bleeding, oil measurement, setting fork oil height, impregnating people and animals.....

Get a Mityvav. It's $30 at Sears and will make filling/bleeding fresh lines a total breeze, trust me.

I have a 96 Bandit and it has Nissin calipers, not Tokicos. They both appear to be twin pot calipers, but I don't think there are many other similarities. Someone with more in depth knowledge might be able to tell you more.

I thought the Bandit's brakes lacked some initial bite, which was easily remedied with new pads. (EBC?) Even now I have no complaints from the brakes that still wear the original lines.
The Versys, however, is terrible. It lacks initial bite. It has zero feedback in the rear and feels wooden up front. I haven't locked the front yet, but have locked the rear a few times and didn't know it until after I heard the squeal and the back end stepped out. Two fingered braking finds my last two fingers squashed between the lever and grip for anything more than light braking. Moderate to hard braking has some feel, but that feel is like something coarse is grinding.

Let me know what you discover. Brake mods have moved to the top of my future farkle list.
