Hello boys, upgraded front calipers to R6R monoblocks, and I'm not sure about keeping the nissin OEM master cylinder. I do mostly street use, and sometimes track days with friends. I'm not fast at all, but I've had sponging problems with the front brake. Will the calipers and a goof bleed be enough to avoid sponging after 5-6 laps? Thanks!

I had spongy brakes and the only fix was a new MC. I went with a Brembo 19 RCS Corsa Corta for the finer adjustability. It was night and day compared to stock.

As far as sponginess due to brake fade, that will be more to do with calipers/rotors/pads. I'm sure others will chime in.

Honestly I think my order of stock brake ugrade would go like this:

SS braided hoses, then pads, then master and then calipers last.

But that's just one opinion (y)

Couldn't agree more. To upgrade (even from the standard stock Tokico which are good calipers IMO) calipers and rotors you need to spend crazy money to achieve an improvement.
Biggest improvement you will see are lines, MC, pads. That's maybe $600 worth of upgrades.

I will once again direct anyone wanting legit, honest, knowledgeable, trustworthy info on all bike related topics to rogue racing.org. Best collection of info on products, upgrades, tech tips, etc all in one place. A member on this site LDH is the author of the articles and is one of the most honest, straight up, helpful, and knowledgeable guys you will find sport bike wise
Man I need to start getting kick backs from Mr 'world's largest Ohlins dealer'!

I used to hang out with the RC51 guys in the early 2000's because there was nobody riding an RC45 on the streets (well besides Larry Lovisone in California but that's another story) and the only place online worthy of the RC51 guys was RC51.org - later rorgue - and since way back when Lord Duck Hunter has provided no-bullshit straight shooting truth.

Yeah I honestly think everyone should read every article on his site before upgrading a single part on their bike. His articles have saved me thousands in worthless upgrades or bad aftermarket part purchases. I can't find a single sentance in any article that I don't fully understand, makes complete sense, and completely agree with.
His crazy amount of experience on and around sport bikes makes his opinions priceless and he's used, rode, tried, and tested almost every part you could think of so it eliminates all the time and money each one of us would individually spend finding the right part for our application.
I can't praise him enough for taking his personal time to write articles for the simple fact of helping others.

Since you mention street riding, just a warning if you are considering ANY of the high end Brembo nickel plated calipers. The nickel finish will flake off and badly corrode if you get the calipers wet. I learned this the hard way with my pair of GP4-RX (recommended by LDH as the least expensive calipers that actually make a difference) that were flaking horribly after just 4 months of being in humid (never got rained on) Houston weather and ended up downgrading to the anodized M4's which according to LDH isn't even much of an improvement over OEM.

The corrosion starts as a little bubble under the nickel finish and it just spreads out from there, which is a tough lesson to learn not all race parts are tolerable for street riding.

I think you got a bad set on plated calipers cuz nickel plating should not flake off under almost any situation unless it was not applied correctly or the metal it was applied to was not cleaned and prepped/treated properly prior. I would contact Brembo especially for what I'm guessing you paid for them

I thought so too, until I went to sell them on eBay and saw another guy selling $3000 "MotoGP" Brembo nickel calipers with the exact same corrosion problem that I experienced. Picture for reference. Already sold them for a hefty loss, but that's the price to pay for street bling.

I'm sure they would be fine if you lived somewhere dry but where I live every morning there's dew on the bike.

Yeah that's crazy. Track racers ride in the rain, mostly in hot areas. Brembo must have had an issue with there nickel plating process, it shouldn't do that.
I could see over time with hot brake dust and heat cycles and pitting from road debri I guess but still for the cost of them I'd expect better longevity.
Stock Tokico calipers on my 06 with 30k plus miles on them didn't have a scratch and gave a higher performance than I can ever push them to on the street
Unless your a fast B or A group rider at the track I wouldn't even bother. Some of the faster guys I have seen were riding a stock bike with mostly stock components and no issues with calipers, rotors, chain and sprockets, stock wheels, stock velocity stacks, air filter. All the crap marketing sucks us into believing we 'need' to be a better, faster rider

100% agree. Would've gone back to OEM if I hadn't foolishly sold them, threw away the caliper spacers, and installed custom ordered ABS brake lines from Galfer to accommodate the different position of the banjo bolt.

Brembo also stopped making rebuild kits available for non-OE calipers so now you're forking out serious cash for "service" since you cannot readily buy the seals and pistons yourself.

Damn that sucks, sorry to hear that. We have all done it though.
All my other bikes prior to my current 2015 I added a few personal touches but never messed with the bike much just rode it. With this one I went down the rabbit hole with carbon fiber crap (don't get me wrong it looks nice but not for the thousands I have in the parts and adds no performance or value whatsoever) and all the typical stuff guys change or 'upgrade'. Luckily in doing some research I stopped before I was buying titanium bolts and carbon fiber wheels and 520 chain conversions with short life aluminum sprockets.
It's an expensive addiction and we all live and learn at the expense of our time and wallets
What I see alot of bike owners in this site and all others doing is not fully understanding the needs of a track only bike VS a street or occasional track day rider. Although it's fundamentally the same, riding a sport bike, the criteria used for modifying or upgrading is completely different.

Well, what I found is that I habe to do some machining work on the calipers to fit them correctly, what I don't understand because stock R6 rotor is 310mm and my 06 RR is 320mm. I thought I would have to make spacers, but it's the opposite.

I've already got an accosato 19x18 MC and it works much better, you guys were wright there. Instead of these R6 caliper, to avoid all the machinning work and everything, I've read here that monoblock tokicos with a good set of pads will work as well or even better than Tha Yamahas. What do you boys think about this option?

Unless you are a club racer or in the A or a fast B group at the track and it will strictly be a track bike I would just save the cash and hassle and stick with the stock calipers.
Even the Honda stock brake pads work very well on the street and for track days. If I were to upgrade I'd look at CL street pads, not the track version

Finally went through it and machined a bit the calipers, the change is awesome. Even though the pads don't push the rotors on all surface, still need to machine the calipers 3mm. Anyway now I have the sensations I was looking for with the front brake, 0% spongy and nice feeling. Thanks
