What is the maximum free stroke length for 15" disc brakes?

The maximum free stroke length for 15" disc brakes is set at 3/4 inch, as this specification is critical for ensuring proper brake function and safety. Free stroke refers to the distance the brake lever or pedal travels before it begins to engage the braking mechanism. This distance is important because it impacts the responsiveness of the brakes; too much free stroke can indicate potential issues such as worn components or misalignments.

In the context of 15" disc brakes, maintaining the maximum free stroke length at 3/4 inch helps to provide a balance between performance and safety, ensuring that the brakes can engage effectively without excessive play. This specification aligns with industry standards, as manufacturers typically define the optimal free stroke length to enhance the braking system's efficiency and reliability.

Understanding these specifications is essential for anyone involved in vehicle maintenance or repair, as adhering to them ensures that the braking system performs as intended, providing adequate stopping power when needed.
