BrakeTech - AxisIron full floater: 298mm Honda RS125, NSF250R & other - 100% Billet machined and Cryogenic treated, Ea., RH
The exclusive BrakeTech AXIS™ series Ductile Iron full-floaters provides a higher coefficient of friction over stainless, with more feel
and feedback at the brake lever. The patented AXIS Design floating
system is many times stronger than conventional semi-floating brake
rotors. The heart of this leading edge system has the floater buttons
controlling radial and axial float only, they are non load-bearing. All
of the considerable braking forces are channeled through the
architecture, comprising over an 800% increase in surface area load
transfer as compared to conventional floating brake rotors...simply far
superior by design!
- Patented AXIS Design - featuring Direct-Link™ load transfer system
- U.S. Patent No. 6,957,726
- 50% greater Tensile Strength and Fatigue Strength: Ductile Iron vs Gray Iron
- CNC machined from billet (continuous cast bar) - not porosity prone gravity cast molds
- CRYOGENIC treatment for improved wear resistance
- Greater thermal transfer capability than stainless steel
- Reduced wear from shear forces - longer rotor life
- Carriers CNC machined from premium grade billet aluminum bar - not stamped plate
- Hard-anodized to military grade specifications
- Made in the U.S.A.
Sintered Metal Brake Pads on Iron?
does indeed exist a universal prohibition against the use of sintered
metal pads on generic cast iron rotors, we have the same warning. But
this caveat is more specifically targeted to old-school gray cast iron
and particularly of the individual molding, gravity feed casting type.
That combination was and is inherently problematic with a propensity
towards suffering from thermal stress induced fracturing. Not good.AXIS/Iron Black GunKote:
This is a rust inhibiting coating which is thermally bonded on to
minimize corrosion. It must be cleared from the pad sweep area before
the rotors become fully functional. Please click here for the one page

The AXIS/Iron on
the other hand is a significantly different animal. Firstly, it is CNC
machined from American made high grade nodular ductile iron, not gray
iron. Secondly, it's a genuine billet part, sawed from continuous cast
bar (which eliminates porosity and the problems associated with that).
Thirdly, it is an inherently stronger material with tensile strength
more akin to steel than gray iron. Plus, besides traditional
heat-treat, we also Cryogenically process them to improve their abrasion
resistance and reduce wear. But bear in mind, they are still "softer"
than stainless steel, which simply stated means you cannot run any pad
you want without the potential for problems developing...
extensively with virtually all the Ferodo sintered metal pads to assure
compatibility with our ductile iron rotors, which is why we can
recommend the Ferodo SinterGrip ST, XRAC and ZRAC pads for this
application. Though along with virtually all other sintered metal
formulations, they will likely result in a somewhat shortened rotor life
compared to the organic alternative. For those with a nagging concern
regarding the wear issue, we recommend the new Carbon/ceramic CP1race
pads. They are a brilliant performer on stainless, and even better on
iron and as such, are more than worthy of your consideration for race
use on all iron rotors.
