Fully floating 2-piece brake disc rotors allow the 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. They use a 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 its competitors.
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. Rotor rings feature 48 directional internal curved vanes for improved rotor cooling.
Fully floating rotors use stainless-steel drive bobbins, minimising rotor stress under even the most severe braking. Drive bobbins are machined from a single piece of stainless steel, giving maximum strength and corrosion resistance. Stainless bobbins reduce the requirement for regular disc maintenance and ensure 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.
EBC’s 2-piece rotors have been quality tested in accordance with the recently introduced R90 brake rotor test routine. This test is the harshest and most rigorous test for brake rotors in the world and is purposely designed to attempt to cause brake rotors to fail. The EBC disc passed the test with ease, completing the full 150 test cycles without so much as exhibiting minor surface crazing, a true testament to the exceptional quality of EBC’s UK made 2-piece rotors.
