Discs
 

Hi
Is there any way of removing the front discs on my Strada from the disc centres. The reason for this is to repaint the centres as it they have some rust spots on them, and as the discs are hardly worn I didnt want to buy new discs.

Cheers

You can drill out the bobbins and then replace the bobbins with full floating items.

Floating Discs
 

Speaking about floating discs anyone know if there should be ..any/none....free/play in the direction of rotation?

TIA

In principle NO. However, I have been running the "S" on track all season with a small amount of radial float. Intention was to junk the discs at the end of the season. Unfortunately it's the carrier that wears so there's nothing you can do about it.

Numpty question...what advantage do fully floatings discs give you?

My standard disc set up on the ST gives me phenomenal stoppers especially now that they're grabbed by P34 calipers.

I need to sort the sponginess of the brakes on my 888, but that's more to do with the master cylinder. Once that's sorted and with some Bendix pads in the calipers I should think they'll be damn near as good.

Can't quite see the need for full floaters, but if anyone can enlighten me?

Basically it stops them warping when they get extremely hot,this is because there is room for the disc to expand on the bobbins.If there was no space at all to expand they would warp immediately.All discs are semi-floating,just that fully floating allows more expansion.

Hmmm… thanks for that Yeti, I will have to have a closer inspection I’m sure I can make 2 or 3 mm back/forth movement in line with the discs rotational direction.

Jasper, where can I get new bobbins?

I got mine from Nelly at Cornerspeed - genuine Brembo ones.

How easy are they to fit?

EASY!!Just a circlip,washer and the Bobbin.Get them from nelly.

Basic advise :

Don't foget a drop of glue or silicon to avoid eventual bad surprises.

Original Brembo floating disks are provided with ...

floating rotors definitely help with heat build up, but the main reason for use is to reduce rolling resistance, the brake pads get knocked off the rotors slightly after an application of the brakes which allows the wheel to turn more freely, as well as allowing both the rotor and pad to cool more effectively.

Plus that make that really cool jingling noise when you move the bike about....;)

Absobloodylutely :sing:

I never heard of that explanation before, for sure one of the –‘s in the extra clearance created by floating discs knocking the pistons back is not good, makes for loose feed back at the brake lever.

Thanks for the fully floating explanation guys. It seems to me that they offer a few advantages under extreme use, but I don't think I'm ever likely to need full floaters at the pace I ride at

Jools,you do-'cos they make that rattling sound!!
