Carbon brakes and floating discs
Discussion
I'm keen to upgrade my brakes and wanted to A look at carbon brakes. And B look at steel floating discs
B is most likely due to costs but seeing as there will not be a kit for either option for my noble just wondered we're people would go for either options if at all?
The reason for the uprgrade is current setup builds heat in disc and alloy bell which I believe expand at different rate and thus get brake jabber on track with potential warped discs... I don't think larger discs are really needed so would like to explore full floating setup or better still carbon as weight reduction has been a key part of the modifications to my noble.

Dont know about carbon, but Bob BG Developments can certainly sort the floating aspect.
It will require new discs/bells though.
Or give Alyn at AS Performance a shout, as he could likely do the same.
Are your discs an OEM fitment, or totally custom ? ie, would there be an off the shelf replacement likely ?
As there are companies who make floating disc arrangements to replace some standard car discs too.
I think I would prefer a disc setup where the float occurs in the bell region. My original AP setup via Bob, and then replacements via Alyn and Performance Friction, both to suit the original bells Bob made have the float within the disc mounts itself.
There is little provision to prevent rattle, and the disc and bobbin wears, which then rattles even more.
More modern stuff have better floating designs, and springs to eliminate any rattles ( annoying at slow speeds on some road surfaces when the system has worn a little )

They can also do carbon.There is an off the shelf custom item available, but it's a much larger disc and semi floating, so comes with a large weight penalty, my car is 1050kgs full of fuel and has 320mm discs as std, I don't really think I need larger and would rather get floating.
I would need bells and discs, I've seen the anti rattle versions on Ashton's etc so will investigate these recomendedvcompanies... Cheers :-)

I posted some pictures of some of the work BGD did for me on this thread

Here are the bells they made for me...
Rear disc bell/hub
Front disc/bell. This is a floating set up.
Cheers,
Mick.

Yes, what look like bolts are bobbins. Here´s a link to AP web page... http://www.apracing.com/Info.aspx?InfoID=65&Pr...
You can also have float in the bell set up, as opposed to float in the disk.

Bobbins arent that expensive.
Bells arent that expensive.
Discs are bloody expensive.
I'd certainly be wanting the float to occur anywhere but the disc. The bobbins are a wear item and can be replaced. Yes discs wear too, but when the friction surface is fine and they need replaced because the floating aspect is worn, it is quite annoying.

So the float is in the disc.... Im going into hopeful mode here, but Is this AP trying to market for the people who already have bells and need new discs but would like to go to floating.You can also have float in the bell set up, as opposed to float in the disk.
Ie can these be fitted to my existing bells?

My kit is several years old and floats in the disc. That was the norm then.Ie can these be fitted to my existing bells?
If there is a disc with the correct bolt number and PCD, then it would be straight forward to switch to floating.
Although you may need to move the centreline of the caliper slightly so the caliper runs in the middle of the "float" if you get what I mean. As the disc centreline would move slightly.
Although the actual amount of float really isnt huge.
For reference, pinched from google images.
Float in bell
Strap drive float. Seen Performance Friction and AP offer this with OEM replacement discs. I like this.
I would imagine with custom bells and normal discs, if you could buy the straps, this should be able to be applied to any disc really.
Float in disc. Special bobbins are required for the bolts.
