Product Details and Specifications

This brake master cylinder features a 1.250 inch (31.75 mm) straight bore diameter, which is critical for maintaining correct brake fluid pressure. The aluminum construction provides durability and resistance to corrosion, while the included plastic single reservoir holds brake fluid securely. The unit comes with a master cylinder cap but does not include mounting hardware, push rod, brake booster, or bleeder hoses. It has three ports with inverted flare types: a primary outlet thread size of 7/16"-24 and a secondary outlet thread size of 9/16"-18, ensuring compatibility with factory brake lines. The part requires one brake pressure switch for proper brake system function, which is not included.

Common Applications and Problem Resolution

• Restores brake hydraulic pressure in Ford Expedition, F-150, and Lincoln Navigator

Installation Notes and Tips

Ensure the brake pressure switch is installed separately as it is required but not included.
