Hi All.
Well after going through all the previous threads I was wondering if anyone has done the following to solve some of the bleeding problems associated with the S2R underslung brake.
Or can answer my questions.....
1/ Has anyone there moved or modifed the rear caliper bracket to mount the caliper up top? IE above the axle.
2/ If no-one has tried this, does anyone think it would be an issue, re handling when braking?
3/ Can the bleeder and banjo fittings be swapped over...I don't feel like pulling mine apart to find out.
Cheers people, look forward to your input.

1) Haven't seen it done, but that doesn't mean it hasn't.
2) I don't think it would make any functional difference to how the brake performed.
3) Pretty sure the threads are different.
is there something wrong with it?
Thanks Speed Dog and Brad.
Nothing really wrong with brake, although has picked up some more free travel.
I really just wanted to satify my curiousity as why top mounting wasn't an option.
Cheers.

I've seen a couple of the OEM masters on S2R and 620 go bad, they were the black ones, '05 and '06 vintage.
I had to bleed my back brake when I first got the bike, but I just had to do it once and it's been fine ever since. I'm guessing you have some sort of a recurring problem, though. Is this a common thing? I can't see why air would get in just because the caliper is upside down, but I can imagine it getting trapped there during assembly.
Either way, it sounds like an awful lot of trouble to those mounting points.
the rear brake setup sucks. just ignore it.
I've bled mine, replaced the master (this worked for a couple months), adjusted the linkage, and done pretty much anything else I could think of.
The rear brakes suck. The mounting sucks. I hate to be so negative, but the engineers must have been out to lunch on this one...
That said, I'm continuing to try. The Gilles Tooling rearsets I just ordered seem to move the master, so maybe that combined with a new reservoir (Rizoma bling) and fresh fluid will finally give me some rear brakes that work for more than a few weeks.

HAhahahheheeh. That wins.
Actually, imho, if you use the rear brake gently when approaching every stop, it might be something other than a heat/noise generator later on in life...
About those threads: I have seen calipers where the bleeder and banjo are the same threads. If the bleeder has huge threads, then yes, probably the same.

i've found my rear brake to work pretty well, despite the suckiness of the setup.
yes, it gets air in it, but it seems to be a consistently minimal amount that i'm willing to deal with.
