Installation Notes and Tips

Installation of the StopTech Sport Disc Brake Pad Set 309.07250 requires removal of the existing brake pads and cleaning of the caliper assembly. Use the included mounting hardware and pad shims to ensure correct pad alignment and minimize noise. Since the pads are prepared for a pad wear sensor but do not include one, verify if your vehicle requires a sensor and install separately if needed. Always follow manufacturer torque specifications and perform a brake system test after installation.
