Shimano BR-4500 is a caliper brake designed to provide reliable and precise braking for road bicycles. Its adjustable toe-in angle allows for optimized braking performance, ensuring smooth and controlled stops. The use of lock nuts with nylon inserts and sealant on sunken nut threads ensures a secure and durable installation. Shimano recommends using genuine Shimano replacement parts and lubricants for optimal performance and longevity. To maintain proper functionality, it's crucial to regularly check the brake cable for rust or fraying and replace it if necessary.
