EBC Ultimax 2 brake pads are designed to match the exact dimensions of original equipment with extremely tight tolerances to ensure proper fit, even wear, and absence of rattles and squeaks. A patented low-metallic aramid compound uses DuPont Twaron composite to reduce the amount of steel wool necessary, so these pads cause far less abrasive wear on rotors without compromising brake pad efficiency or longevity. In government R90 tests of replacement brake components, EBC pads have shown to deliver equivalent performance, bedding, cold temperature operation, and speed sensitivity when compared to original manufacturer parts. EBC's aramid material also ensures the pads are soft enough to avoid brake squeal, but not so soft that pad longevity becomes compromised. EBC Ultimax 2 brake pads also feature a red top layer coating designed to scour glaze and hot spots off worn brake rotors during the break-in process. The coating also serves to provide a higher level of grip to counteract low friction levels that exist before bedding is complete. Built-in shims ensure any high-frequency vibration is absorbed rather than transferred as squealing noise, even under the most extreme weather conditions.
