Reduces the difficulty of manually adjusting the brake calipers by quickly equalizing the gaps between the left and right brake pads. Helps prevent abnormal brake pad rubbing by aligning the disc brake pads precisely, improving braking consistency and reducing noise. Made from stainless steel, offering strong, durable performance and resistance to damage even after prolonged use. Specifically designed for disc brake gap indicators; the pad inserts tightly and resists slipping for reliable operation. Applications After replacing brake pads on a disc brake system, quickly equalize the left and right pad gaps to ensure symmetric braking. During workshop maintenance to prevent pad rubbing when installing rotors or adjusting calipers. For routine setup to maintain consistent pad clearance across multiple wheels.
