Installation Notes and Tips

Before installation, inspect the brake booster, lines, and fluid condition to confirm the rest of the system is clean and serviceable. This master cylinder does not include a reservoir, cap, push rod, brake booster, sensor, dust boot, or mounting hardware, so verify all related components are transferred or sourced separately as needed. Bench bleeding is recommended before final installation, followed by a complete brake system bleed to remove trapped air.
