The specification for brake hardware on Harley-Davidson motorcycles, particularly the size of the 12-point fasteners used in their brake systems, is not a single, universally applicable dimension. Different models, production years, and specific locations within the brake assembly (caliper mounting, rotor attachment, etc.) necessitate varying sizes of these specialized bolts. Identifying the precise measurement requires detailed knowledge of the motorcycles year and model, alongside the specific component being addressed. For instance, a bolt used to secure a brake caliper on a 2018 Softail might differ in size from a similar bolt on a 2023 Touring model.
Accurate specification is crucial for ensuring brake system integrity and safety. Incorrectly sized fasteners can lead to insufficient clamping force, potentially causing component failure and hazardous riding conditions. Furthermore, using the correct tool size is vital to prevent damage to the bolt head, which could lead to difficulty in future maintenance or repairs. Historical context reveals a gradual shift towards standardized sizing within specific model families, but variations persist due to design changes and performance enhancements throughout Harley-Davidson’s history.
