Installation Notes and Tips
Verify vehicle fitment by year, model, and front disc brake configuration before installation. This master cylinder does not include mounting hardware, push rod, brake booster, or seals, so inspect related components and transfer only serviceable parts as needed. Bench bleeding the master cylinder before installation helps reduce trapped air in the hydraulic system and supports proper pedal feel after bleeding the brakes with DOT 3 fluid.
