EBC's Severe Duty "SV" brake pads are made of a high density sintered copper alloy for longest possible life in utility applications on ATVs, especially in wet, mud, dust and dirt conditions. Designed primarily for ATV use in tough riding conditions, "SV" series pads are a high density version of EBC's "R" pads. Being higher in density these pads last longer than anything else in the EBC family and will stand up against any pad you can buy. They are also very low in rotor abrasion and will not damage your brake rotor.
