EBC USR Series Slotted Brake Rotors (USR1449)

EBC ‘USR’ brake rotors feature a heavily canted groove profile that provides all the de-gassing and debris evacuation benefits associated with a grooved brake rotor but with slightly reduced ‘bite’ during brake application for a smoother braking action. The shallow angle of the grooves also helps to keep brake rotor noise to a minimum, making USR brake rotors a popular choice among owners of prestige vehicles, who seek the performance benefits and improved aesthetics of a grooved rotor but also whilst keeping brakes quiet.

USR brake rotors are also well suited to off-road use, where the straight-cut grooves allow effective evacuation of sand, dirt and water present at the braking zone. Off-road users report longer pad life and less rotor ribbing when using EBC USR rotors vs. cross-drilled/dimpled rotors and even vs. plain non-grooved brake rotors, where sand/debris can build up at the braking zone and accelerate wear.

EBC USR brake rotors, like all EBC 1pc brake rotors, are cast from a high-carbon G3000 rotor alloy, boasting excellent thermal capacity and high resistance to both warping and cracking, even when driven hard. Unlike some other manufacturers, EBC sees no benefit in offering a ‘lower-performance’ or ‘low-carbon’ brake rotor range, since the use of poorer metallurgy can decrease rotor life and performance yet shaves mere cents off the manufacturing cost.

The outstanding quality of EBC’s brake rotors is evidenced by the fact EBC Brakes is one of the first and only aftermarket rotor manufacturers globally that has both TUV and R90 approvals on their brake rotor range. This is in stark contrast to some other brake rotors available in the marketplace originating from the far-East, which often aren’t approved to TUV, R90 or indeed any other internationally recognised quality standard. EBC’s commitment to product testing means EBC’s brake rotors are fully compliant with ADRs and thus legal for use on public roads in Australia.

Every EBC rotor is machined using a ‘twin-turning’ process which guarantees near-perfect parallelism. This process reduces the likelihood that Rotor Thickness Variation (RTV) could manifest on the vehicle, which could otherwise create brake judder. Machined rotors are then run-out tested to ensure they meet EBC’s strict tolerances. Finally, every finished rotor is first Geomet® coated to protect all surfaces from corrosion, then rotors are additionally sprayed with an advanced anti-corrosion black coating to further protect visible non-contact areas from unsightly rust for an extended period after installation. This double-finishing process gives EBC brake rotors maximum protection from corrosion.
