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 trademarked Direct-Link™ architecture, comprising over an 800% increase in surface area load transfer as compared to conventional floating brake rotors...simply far superior by design!

Iron provides a higher coefficient of friction over stainless, with more feel and feedback at the brake lever. But get them wet - they're going to rust. If you're a fair weather rider, then it's a non-event and not an issue. However, if you ride distances where inclement weather is a definite possibility, you're better off with our AXIS/Cobra stainless steel series in the optimized petal design.

Sintered Metal Brake Pads on Iron?

There 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.

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...

We test 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 CP1 race 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.


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 instruction guide:  AXIS/Iron Rotor Clearing instructions

Begun back in the mid-90's, our benchmark Hi-Tech Cryo Treatment is applied to all BrakeTech premium performance rotors.  This -300º below zero computer controlled process is an advanced material enhancement system which alters the matrix composition of the metal at the molecular level.   While improving rotor durability it also maximizes performance on the track with today's high coefficient of friction brake pad compounds.

At BrakeTech, we strive to bring you the best in braking...
