EBC Brakes manufactures many of its rotor ranges in ISO and TÜV approved facilities in the UK or in Italy. We have accredited foundries now on line to ISO and BS5750 standards that we have now carefully selected and visited to replace the UK supplies as we continue our goal to bring only the finest products to our customers. All rotors including GD Sport Rotors are machined and finished in the UK or in the USA.

Quality Castings For An Excellent Product

Where castings or finished rotors have been bought in to complement the range, the strictest quality controls you can imagine ensuring the safety and quality of the parts we sell. EBC adds value to its products by strictest quality controls and specifications and a 100% run out, metallurgy, and dimensional check, plus all USA sport rotors are slotted in housed at either at the Las Vegas facility of the USA operation or in the UK. All sport rotors are then balanced and runout inspected before release.

EBC Brakes produces all of its GD series and USR discs with a long lasting corrosion resistant finish. The coating is either the world-famous thermic black which protects the off-brake areas of the rotor from corrosion such as inside the pad swept area and inside the hub.

Thermic Black & Nitrotherm™
The wide aperture slots in the GD Sport Rotors series have been shown to reduce brake temperatures by up to 100 degrees by drawing cooling air beneath the brake pad under load. The super silent Ultimax USR slotted series also run cooler along with the new bi-directional BSD series.

All designs offer benefits such as:

• Cooler brakes
• Resistance to cracking is possible through drilled rotors
• Water mud and debris are expelled from the brake area by the slot pattern which is fully machined to the edge of the rotor for this reason. (Slots that stop short of the rotor edge can cause pocketing of debris and generate a rib on the rotor outer edge.)
• As the pad and rotor wear the slots maintain a perfectly flat and smooth pad surface and prevent rotor ribbing.
• On a global scale, most EBC rotors are made from high quality G3000 or G3500 high carbon castings and 100% of these are precision machined , balanced and runout inspected in either the UK or the USA.
  

Dimple Drilled Rotor

The dimple drilled rotor was invented by EBC back in the 90’s and has been imitated by many because of its ability to offer pad degassing without “Through Drilling” disc or rotor holes which has been shown to promote rotor cracks. The wide aperture slots on the EBC units actually draw cool air under the brake pad and rotor interface and help cool the temperatures of the pad contact which can shoot up to well over 1000 degrees at the very heart of the brake pad during heavy braking and can cause brake fade or loss of brake effect.

There are four choices of sport rotors, premium non slotted OEM style, GD, USR and BSD designs and as wear occurs all can be skimmed and life extended many times using this on-car brake lathe. A perfectly flat smooth and aligned USED rotor can often be better than a new rotor as the casting matrix settles over time. Many OEJM car builders actually skim rotors on the car from NEW to align them to the car and the cut, which only removes a tiny amount does not render the disc/rotor below minimum thickness if done correctly.
