Brembo Radial Calipers on eBay

$400 doesn't seem too bad.

 

....of course, you'll need new forks, an "adapter of some sort", or new fork caps to use them.

 

 

Just an interesting aside, from simply looking at the photo, these seem to basically be built the same as the higher performance "axial mount(normal)" 4 pad Brembos, with the exception of the new radial mounting design.

 

As shown in this thread, these are the 4 pad calipers to which I refer:

Does anyone know if these radial calipers are really technically any different than the "axial' 4 pad calipers, again, other than simply being radially mounted?

 

Just curious from a technical standpoint, as I don't plan to retrofit my forks with new end caps.

Umm, pardon my ignorance, but what's the difference between axial and radial mount?

Radial - The mounting bolts of the caliper align along a radius from the axle(not perfectly, but in general). This is the latest design you see on most "high performance" bikes.

 

Axial(traditional) - The mounting bolts of the caliper are parallel with the axle. This is the standard mounting arrangement you have seen on bikes for decades. What's funny, I don't think anyone bothered to call this design "axial" per se, before we had "radial" versions to differentiate the two

 

 

Example:

 

Radial

 

 

 

 

 

Axial(traditional)

.... I'd post a picture of them installed, but all you have to do is walk out to the garage and look at your front calipers

 

 

When it is all said and done, the radial calipers are said to stop better and provide improved "feel" in that the radial mounting is more rigid. At least that is what the marketing says

 

 

Hope that helps.

Its fashion hype.

 

A properly designed, rigid mount will feel the same regardless of the bolt placement.

 

Maybe the designers feel that by making a "radial" mount they can get the same rigidity with less metal, and hence reduce unsprung weight. IMHO that would be a sensible argument for it if true. All this talk of better feel and better braking is just bullshit.

Brembo make a kit which enables you to retrofit radial calipers but its bloody expensive.

And pointless since there is an intermediate bracket that picks up on a non-radial fork bottom, effectively converting the caliper into a less stiff and heavier version of the conventional non-radial type!

And if you have the right make of forks, Ohlins for example... as mentioned in my first post, they do make replacement fork ends for changing out the brake caliper mounts.

 

These too are "bloody expensive" though, not even taking into account the labor required to actually make the change as well.

 

 

I agree though, that mounting an "adapter" is a waste of time, unless one is simply going for "bling" factor

Hi Al,

 

Actually, the Ohlins forks that come stock on some Guzzis don't have removable fork ends. That's why Paul sold me his forks. He needed different Ohlins forks to have radial calipers.

 

BTW, upgrading to a radial brake master cylinder makes a big difference in braking feel. I would believe that doing that would be a much better upgrade that to radial calipers and it's a whole lot cheaper. As a bonus, you get an infinitely adjustable handle.

thanks for the info.

I can see perimeter brakes being referred to as radial, but I don't see how these are. Maybe we should come up with tangential brakes. hmmm, then again maybe that refers to drums...

We can tell it is a non sense to fit radial calipers without a radial master cylinder.

On missing Mss Dayto it was a Brembo BILLET 19/20 & this little expensive part have an incredible braking power changes.

 

Even if i only made 35 km with it before disapearing

Al/All,

 

I can get them (GuzziTech.com) for $222(USD)/ea brand new (same exact price as the 4-pad axial mounts); http://www.guzzitech.com/Brembo-4padcal-Todd_E.html

 

I ship Worldwide.

 

I also sell the radial m/c. Sold one to KenM above and he's stated they work really well, even as the only mod. My entire upgrade parade summary here; http://www.guzzitech.com/Brembo-Upgrades-Todd_E.html

 

Let me know if I can be of help for anyone,

Todd
