Title: moto-master floating brake disk
Post by: totty on September 24, 2014, 07:56:34 PM
Does anyone have any experience of these? Are they an improvement?

This doesn't make sense.

Floating discs are designed for bikes with fixed calipers, quite how a floating disc with a floating caliper would work I don't know. Unless your caliper has seized of course!

With you on this one Steve. Floating caliper and disc?

A "fixed" caliper has both pads fully floating as the Honda swinging caliper has one part fixed (it can't back away from the disc more than has been set for clearance) and only one true floating pad.

I hadn't given the float a thought, but I'm now wondering if it would be an issue.
I was wondering if anyone had tried one and if it proved more effective as it's probably a different material.

I've got no derict experience of that product.

Thechnically the "float" refers to the disc being not fixed in a rigid fashion to the carrier to prevent a thinner disc braking surface from distorting under heat/load, the non rigid fixing alows this to happen without causing the surface to deform and so keeping the disc more dimensionally stable and tracking straighter as it goes through the caliper.
You may have to play with clearance settings to see if it's needed to deviate from std but I would expect the braking performance to be improved when cold and wet as the thinner disc should come into normal operating temp much easier.
