Disc Brake Gap Regulator and Caliper Alignment Tool Easy and accurate caliper alignment: reduces the difficulty of manually adjusting the brake caliper, quickly equalizes the gap between the left and right brake pads, and helps prevent abnormal pad rubbing. Clamp/caliper positioning: designed for hiking (mountain), road, city and other bicycle rotor disc brakes. Adjusts the brake caliper position to avoid scratching the rotor during setup. and durable: made of quality stainless steel for reliable longterm use; resistant to damage with extended use. Portable and lightweight: compact size and light weight make it easy to carry on road trips, commuting, or daily rides. Compatibility and performance: a practical tool for disc brake systems to maintain proper pad spacing and caliper alignment, helping maintain smooth braking. Use scenarios Routine maintenance on a ride or at home: quickly set equal pad gaps and ensure the caliper is aligned to prevent rotor rub. During pad or rotor replacement: align the caliper and pad positions to avoid rotor contact and ensure consistent braking performance. On long trips or tours: keep brakes properly aligned in variable conditions, reducing the chance of pad rubbing and rotor scoring.
