Bench bleeding the master cylinder before final installation helps remove trapped air from the hydraulic circuit. Because mounting hardware is not included, reuse or source the required hardware separately if needed. After installation, bleed the brake system thoroughly and confirm a firm pedal before returning the vehicle to service.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eThis Dorman brake master cylinder is precision-engineered to match original design and performance requirements for the listed applications.
