AXIS 320mm / 12.6" Full-Floaters
BIG-BRAKE CONVERSION KITS
Our Big-Brake kits for the Harley big twins is all about performance. Consists of our patented AXIS series 320mm (12.6 inch) full-floaters in either race-spec Ductile Iron or our stylish Cobra series stainless steel in optimized petal design. Add into this robust billet machined caliper adapters in the Black Diamond hard anodize finish to fit the Brembo 4 piston twin-pin calipers, arguably the world standard of performance. The Brembo calipers are not included in any of these kits and must be purchased separately.
This upgrade kit is designed with the very serious, performance oriented enthusiast in mind where aesthetics, though important, take a backseat to those looking for a genuinely big boost in braking!
The advanced design AXIS™ full-floaters offer substantially improved performance in terms of both modulation at the lever and overall braking power. The patented advanced floating system of the AXIS series full-floaters is many times stronger than conventional semi-floating brake rotors. The heart of this patented design 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 a far superior design!
Plus we are the first major brake rotor manufacturer to include hi-tech Cryogenic processing on the entire line of performance rotors as a standard operational component of manufacture. The inclusion of this advanced technologically employing computer controlled, 40 hour deep freezing treatment provides greater thermal stability along with improved wear resistance.
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 like me, 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.
The following details the range of brake pad compound offerings from Ferodo for the Brembo 4-pot / twin-pin calipers:
Although not an ultra high friction compound, the Platinum™ organic pads have the most feel and modulation at the brake lever and is the Number One performing organic road friction material for a broad cross-section of street bikes. Developed from technology gained from Ferodo's World Racing program, the Platinum compound offers excellent all-around braking response with a co-efficient of friction level that is both linear and consistent.For real-world street use with stainless steel or iron rotors, we recommend the high performance Platinum pads as they are remarkably user friendly offering great overall power and modulation for those that do not prefer a high level initial bite. The result is superb feel and feedback at the brake lever with the added benefit of low abrasion which is very kind to brake rotors
The Platinum organic compound is also the dominant material used extensively in both MotoGP and World Superbike as "the" rear brake pad due to its incredible feedback and added control it delivers at the pedal. AHRMA Vintage class roadracing is yet another venue where the Platinum organic provides an optimal blend of power and control for a large cross-section of these classic series race bikes.
• FDB2042P; Platinum organic - Brembo twin-pin
Ferodo SinterGrip ST brake pads represent the very latest in leading edge technology of sintered metal friction design. These new pads provide outstanding performance not only in setting the standard for all-out braking power, but in truly remarkable feel and feedback as well. Designed to be kind to stainless rotors, this advanced composition friction material allows the wheel to spin much more freely in comparison to other HH brand brake pads that create a power robbing and excessive brake drag situation on the rotor. The FERODO SinterGrip pads offer incredible stopping power combined with precision control, minimal brake drag, lower operating temperature and quick bed-in for a significant improvement in overall performance.
• FDB2042ST; SinterGrip HH-rated
The new SinterGrip XRAC series sintered Factory race pads feature the culmination of our ongoing development of sintered metal technology with the Factory Yamaha teams from both sides of the pond. This formulation offers superb power and control with excellent thermal stability. In addition, it features the introduction of our new and trademarked Array Cooling technology to reduce friction material smearing under severe thermal load conditions. Relatively high initial friction with powerful, but user friendly torque characteristics that offer late braking consistency, lap after lap. This compound features special adaptations making it not only compatible on the CMC rotors, but a terrific performer as well.
• FDB2042XRAC; Brembo twin-pin Race
The all new Ferodo ZRAC race pad range does not replace the recently updated XRAC, but rather is a very focused and limited product range that features the trademarked HIT™ (High Initial Torque) technology which simply translates into a higher initial coefficient of friction for more more initial bite than the XRAC. But it doesn't stop there, this is combined with an extremely high peak friction for an amazingly powerful brake system. The intent is to offer more performance options for Pro level racing as well as seasoned club racers who prefer the characteristics of a flatter torque curve. Feel and feedback at the lever is superb providing excellent control during late braking corner entrances while it's thermally stable friction characteristics maintain linear progression to peak power under maximum pressure. As with the XRAC stablemate, the all-new ZRAC also features the trademarked Array Cooling™ technology to reduce interface temperatures under severe thermal load conditions.
• FDB2042ZRAC; Brembo twin-pin Race
Also new is the long awaited and brilliant performing CP1 organic series race pads. This replaces the popular and long standing CP211 carbon/metallic pads with an entirely new friction composition technology incorporating advanced Siloxane polymers into a truly innovative Carbon/ceramic matrix. This is not a case of simply adding ceramic particulates (friction modifiers) to the mix but rather and a new and different approach how organic composition racing brake pads operate. Provides tremendous power and control at the brake lever with a predictable and reassuring rising torque curve for that added power, deep into a corner – whenever you need it, time after time. Performs brilliantly on stainless and even better on our Ductile Iron brake rotors. Plus very low abrasion as well.
