S2R 800 -> S2R 1000 brake conversion

yeah that was a lot of reading... I know the theory of brakes and how they work, but the interchangability of parts is what gets me.  Seems like it's all smoke and mirrors from the mfg...

going back a post or three...

What is your caliper setup?

If you have a single front caliper, you can get a 16x18 Brembo Radial Front Master
If you have two front calipers, you can get either a 19x18 or 19x20 Brembo Radial Front Master. There is a new series from Brembo out now that allows you to order one caliper and choose whether you are in a x18 or a x20 mood. The difference is "feel" and abruptness of braking action.

i'm on a 04 620 with 2 calipers on the front.  So you're saying I could get a radial master with either of those stroke measurements, bolt it on, run new lines to the calipers and I'd be done?  well, throw reservoirs in there.

Well, if you've got single piston calipers, then investing in a upgrade would probably be worthwhile. The price of a cast "GP" radial master or a take-off 749/999 (eBay) radial master is low enough that its worth a try to see if you like the feel. The parts are all resell-able (though if you put fluid through it, not returnable).

I don't see why it wouldn't work, but I haven't done it myself to give you a confirmed "yes" answer.

You can measure and order your own lines and fittings directly from Spiegler and they are great to work with. They also vend some non-peecup reservoirs as an alternative to Rizoma, and they have all the appropriate fittings. Whenever I have a question about what I need/want, I give them a call. Very fast and helpful.

The bore x stroke was my first stumbling block.  Someone said "look on the bottom and find the number, then get masters that match."  Well, try as I might I couldn't find it on the bottom of my masters.

I have the 65mm axial mount dual front calipers.  I did have a guy once tell me "those are nice brakes" when I first got my bike but i was (and still am) pretty ignorant to the subtleties of ducati part sourcing.  They're the gold colored brembos, but other than that.. /shrug.

I always figured a radial master would only work with radial brakes.  again, my own ignorance.

Andy, can you post a picture of your brakes?
If you have an S2R800, and the calipers are GOLD, it sounds like someone already did a brake upgrade on your bike.
Chances are it now has the GOLDline brakes... which include 65mm axial mount GOLD calipers up front, each with FOUR pistons, TWO pads. Also would include 320mm rotors with a Gold snowflake looking center. And probably a larger bore coffin-style master.

The STOCK S2R800 brakes have coffin masters, 300mm silver rotors, and 65mm axial mount BLACK calipers up front, each with only TWO pistons and TWO pads.

A pic would help confirm what exactly you have.

But from the sounds of it, you already have upgraded brakes compared to the stock S2R800 setup.

The only difference between the goldlines that i THINK you have, and the S2R1000 brake setup, is the color.

Lastly is the rotor's bolt setup: 5 vs. 6 bolts. All the Duc's I've come across are 6 bolt, but that doesn't mean that there's a line out there that I didn't notice came equipped with something different.

749, 999, and 848 have 5-bolt

[junior varsity]

Ah, same for 1098?

[corey]

Not sure.

andy, i now see you weren't the original poster, and are on a 620, not an S2R800.
from what i understand, however, some of the EARLY 620's DID come with goldline brakes, rather than the crappy 2piston/300mm setup up front.
plz post pics so we can confirm...

up to early '05, the 620s had the 4 pot brakes (and metal tank), it was apparently a running change through that MY.

i lucked out, as mine was an early build 05

yeah, its really hard to make a hardline generalization about a particular model and what came with it. They are parts-bin specials. My M900 has an aluminum swingarm, 3-way adjustable showa forks from the S model, but the really horrendous boge-sachs shock. Its an "S" without all the parts, so they labeled it a standard M900, and I lucked out.

Its not too unusual for others to report getting something better than normal by luck on their bike.

so I've had time to look into this some more.  I'd still like to upgrade my master cylinders to get more lever and handlebar options.
when I look in the techincal manual I see this:

Code Select Expand

Brake caliper     Make                      Brembo
                  Type                      PF 2x28 - 2 pistons
                  Caliper cylinder diameter 30 mm - 34 mm
                  Pads friction material    FERIT I/D 450-FF
Brake master      Type                      PS 15
cylinder          Master cylinder diameter  15 mm

and here's what the front looks like: (thumbs)


I feel dumb asking all this, but I can't seem to get 2 and 2 to make 4. 

[teddy037.2]

you've got the same brake setup as mine... 4 piston calipers, coffin masters.

I got these master cyls, which did seem (to me) to give better braking performance... not like substantial, but noticable difference.

which, looking at specs, the 996 master has a 1mm larger piston than the monster coffins.


radial masters will still be the 'best' choice, but swapping out for the goldlines did make a difference. and I didn't need to swap lines, either, so it's still the cheaper, 'bolt on' option

[junior varsity]

My M900 came with those goldline masters shown in Teddy's post.

They are 'good'. There's notable advantages to that setup over the coffins.

You could go ape shit, as I did, and opt for some radial masters. The cast model of the Brembo 'GP' radial 19x18 or 19x20 isn't that expensive. I'm not sure the pricing on the new RCS line, but I imagine its more than the cast 19x18, which is a real bargain.

Here's the issue, you'll face: They don't make an inexpensive cast clutch master. They only make a billet. So to have 'matching'-ish masters (both radial) you'll be forced to shell out some REAL dough. And then you'd still have a cast and a billet, so not a perfect match. (I quit caring about matching right about now). To 'fully' match, you'd have to go billet and billet and that's damn near a fortune.

What's a similar option, uses the goodness of used parts, and the classifieds/eBay is the SBK 'radial' setups. I think they are very good, almost as good as the 'GP' Brembo lineup, and they can be had for relatively inexpensive off crashed bikes or other parted out rides on eBay or in the classifieds. Sooooo, be on the lookout for the 999 and newer series brakes as well.

Another advantage to going with OEM equipped masters, is the fancy lever companies will make aftermarket squeezers for your paws. No such luck with the 'GP' lineup. You have black, or you have folding black, but if you want bling, you are going to have to do some thing else.

I know an advantage of switching to gold-lines from coffins is not having to change brake lines but, its worth mentioning that going to a Spiegler braided line setup is inexpensive, improves lever feel (by not flexing or expanding as tired factory lines may do), and can look however you like it to. If your bike is a little older, it may have a 'manifold' in the middle of your triple setup, to split the lines down to the front calipers. This is pre T-junctions in brake lines, or if not, its leftover parts from then. Either way, it sucks nuts. I've used Spiegler numerous times (I know there are other available fancy lines out there) and have always had a great experience. See also: a bajillion color options.

yeah that's what I was hoping to do, but I wasn't sure what would just bolt on without needing new lines, new calipers, blahblahblah.


thanks everyone.

in the way of radial masters....
you can pick-up a new or used Yamaha R1 MC ...its a Brembo!

[Privateer]

sorry to revive an old thread, but I didn't want to have to explain too much back story

I've been keeping my eye out for some new MCs to swap out my coffins and I came across these today http://cgi.ebay.com/ebaymotors/Brembo-pump-for-Ducati-999R-clutch-and-brake_W0QQitemZ120521275420QQcmdZViewItemQQptZMotorcycles_Parts_Accessories?hash=item1c0fa0b81c


Anyone know if that, or something like it, would go onto my 620 without too much grief?


Thanks
Andy
