I didn't say fully floating. I said they float…
Fair enough…. When I hear float I understand fully floating
…it's via metallurgy but the effect is similar to a supercar rotor although it's nowhere near as pronounced and they don't clink when you shake them.
I’ve never heard the term metallurgic float and don’t really know what that means…
For me, installing race brakes is not my day job, but AIUI the rotor is either bolted tight to the hat and can’t move or it’s bolted tight but with other hardware in between the ring and hat (like stainless drive bobbins in slots that allow movement movement between the ring and hat or similar hardware).
And I always understood the purpose of fully floating discs was primarily to cater for expansion of the ring so as to reduce rotor stresses and thus rotor cracking under severe application.
I’ve also heard of pad knock back but if fully floating rings resolved such issues then supercar drivers wouldn’t do pre corner brake touches. So I’m not convinced about that but I’ll defer to those members that play on tracks
Whatever the case, such brakes are overkill on public roads. Only in NT can one drive at 130kph? max while other parts of Aus we are limited to 100 or 110 max
Such slow speeds are hardly enough to see rotors explode due to heat stresses as was seen in supercar racing
And if your caught by Police going in hard at every corner, you might find a “driving without due care” or “dangerous driving” charge on thecards. Really, sensible driving on public roads should never see us get close to the capability of fully floating rotors to justify them on performance
The police are confident in the bigger police pack rotor and single cylinder mondo caliper and they punish their cars on the road. But me, I like the Brembo and floating rotor look so I justify them on such a vanity basis… yes vanity drives us all
