THE NEW COBRAMX OFFROAD RACE ROTORS ARE HERE

The new CobraMX Billet Iron rear race rotor kits are like nothing you’ve seen before! This ground breaking technology for top level Offroad Racing and MX heralds from our years of extensive background in roadracing. Unlike the gray cast iron brake rotors in your car or truck which are individually molded, the BrakeTech billet iron series is machined from U.S. spec nodular iron billet (aka ductile iron). Ductile iron has a substantially higher tensile strength than gray iron which in combination with its higher yield strengths is similar to AISI 1040 steel. Also features a microstructure that resists thermal stress induced fracturing well beyond the limits of gray iron. Combine this with its inherent Thermal Conductivity advantage (see attached comparison chart) and the compatible Ferodo SinterGrip SG rear race pads and you end up with a premium rear brake system the provides the following and more:

The modern OE rear brake calipers found on nearly all offroad and motocross bikes have come a long way in since the drum rear brakes days of the mid 80’s. Far more performance loaded with greater control, ease of changing out brake pads with a wide variety of compounds and quite effective in the overall. However, for serious enduro and desert racers, rear brake fluid boil can be a potential spoiler in races with lots of technical down hill sections and areas requiring heavy rear brake usage.

BrakeTech is now addressing this with specially engineered ventilated stainless steel pistons of proprietary material that all but eliminates those shortcoming. Our engineering solution incorporates an innovative fluid maximizer that increases the total fluid volume in the brake system:

These new race pistons should also aid in keeping the pedal from going soft during the heat of battle on the track. The proprietary design of the BrakeTech Caliper Racing Pistons increases of the total volume of fluid within the system further improving thermal stability.

The new ventilated racing pistons are manufactured in the U.S. from American made stainless to provide greater thermal stability for racing applications.  This translates into much more consistent braking under extreme conditions.  No more losing the rear brake in the second half of the race, suffering the effects of fluid boil.  The difference between the OE cast steel pistons and our new ventilated Caliper Racing Pistons can provide the critical difference in winning or losing a race.
