Installation Notes and Tips

Verify the bore diameter, mounting hole layout, and fluid type before installation. Bench bleeding the master cylinder before connecting brake lines helps reduce trapped air in the hydraulic system. Confirm the vehicle uses front disc brakes and transfer any required components not supplied with the unit, including mounting hardware and the brake booster if applicable.
