- Fully floating 2-piece rotor that allows outer ring to expand freely in response to heat. This reduces stress which in turn extends rotor life and reduces the tendency for rotor cracking during extreme use.
- Drive bobbins machined from a single piece of stainless steel giving maximum strength and corrosion resistance. Stainless bobbins reduce the requirement for regular disc maintenance and ensures the outer ring continues to float freely even when used on the public road with corrosive salts and other road grime.
- Each bobbin assembly features an anti-rattle spring clip ensuring silent operation when driving on the public highway
- Rotor rings feature 48 directional internal curved vanes for improved rotor coolin
- Friction rings are cast from high carbon G3500 alloy giving excellent wear properties and improved thermal capacity. All EBC disc rings are cast using the ‘centre split’ casting method, ensuring a balanced casting that will not distort under high heat, an issue common with cheaper ‘moulded out’ castings.
- Unique Swept Groove slot design for effective evacuation of braking dust and gasses whilst ensuring good initial ‘bite’ on brake apply
- Replacement disc rings for EBC floating rotors are significantly less expensive than our major competitors.
Brakes are the most safety critical part of any moving vehicle and in the case of cars and motorcycles quite often when brakes are used in anger, standard is just not good enough. The sport street use or trackday and race use of motor vehicles and motorcycles has led to a need for higher performance brakes such as disc brake pads and brake rotors or discs.
So what does high performance mean and how do we measure this performance ? Brake pads which are made of blends of petro chemical resins and other ingredients are made to a budget by car builders and are one of the first thing to be changed on a vehicles brakes when users are involved in sport or race use. A high performance brake pad will be one which has good friction level and pedal feel on first application and can hold this level of performance throughout the whole braking cycles. Brakes must not “Fade” or fall on in performance under the heat of braking. Not only must high performance brakes work effectively under heat and load they must have good durability. Additives such a copper or coke are blended into pads used on high performance brake systems to enhance durability.
Brake fluids are also tested in high performance brakes and because most fluids are hygroscopic meaning they absorb moisture a higher specification fluid is needed and even that will need regular changing and flushing to keep brakes up to par with the target usage.
Finally the brake rotors themselves must be of a decent quality G3000 Grey iron or better and if possible made from virgin alloy ingot rather than reprocessed irons which are common in 99% of aftermarket brakes. Years ago rotor castings used for automobile brakes were annealed or atmosphere aged to allow the castings to settle after being made. No longer does this happen due to cost restraints on brakes particularly by car builders and so the duty of care falls upon the brake pad to work effectively but not to cause damage to the brake rotor by overheat.
By virtue of the physics involved, brakes work by exchanging kinetic energy or momentum into one of three other energy forms, these being heat light or sound. There are no others. Therefore as it is desirous not to have immense noise from brakes and light would only be obtained by massive over heating of the brake rotor, heat is the method by which the energy exchange in brakes occurs.
This means that brakes can glow orange in high performance use, pads can overheat and fade and rotors could even develop cracks if the brake system is not designed correctly.
In automobile applications cooling of the components within the brakes is usually aided by the ducting of cool air which involves scoops in the front vehicles body work directing cool air as the car is driven onto the brake components. This can reduce overheating of the brakes by 30-40% and prevent caliper seal damage as well as rotor over heat and pad fade.
