EBC WATER GROOVED series brake shoes are made using either high pressure Die cast aluminium platforms for most two wheel machines or pressed steel platforms for most ATV’s with bonded brake linings. All shoes are then radius ground and edge trimmed to fit precisely in your brake drum and also feature lead in and lead out chamfers at lining ends and original equipment style brake shoe springs. The multiple angled liner grooves are designed to channel away dirt, dust,water and debris from the braking area to improve braking and extend shoe and drum life. In early years mechanics would “Saw” these grooves into liners which we do not recommend even though ZERO EBC brake shoes contain any dangerous fibres. CAUTION – ALWAYS REPLACE BOTH LEFT AND RIGHT BRAKES AT THE SAME TIME on ATV four wheelers to avoid dangerous side to side brake pull which can cause your vehicle to pull sideways and cause an accident.
