Details on Centric Premium Brake Master Cylinders

The Centric Premium Brake Master Cylinders product line focuses on delivering precise hydraulic control and durability for brake systems. This line uses high-quality cast iron for the master cylinder body, providing strength and resistance to wear. The removable plastic reservoir design allows for easier maintenance and fluid replacement. The 130.34102 part number represents a master cylinder tailored to meet the specifications required by BMW 3 Series models such as the 325e and 325i, ensuring proper fitment and function within the brake hydraulic system.

Technical Description and Specifications

This brake master cylinder features a straight bore type with a bore diameter of 0.813 inches (20.638 mm), which is critical for maintaining consistent hydraulic pressure. It includes two outlet ports, both with M10-1.00 thread size and bubble flare type fittings, suitable for connecting brake lines securely. The master cylinder is constructed from cast iron, enhancing its structural integrity under braking stress. While the plastic reservoir is removable, it is not included with this part, and neither are mounting hardware, push rod, brake booster, or bleeder hoses. The unit comes with a gasket or seal to ensure a proper fluid-tight connection during installation.

Common Applications and Problem Solving

  • Replacement for worn or leaking master cylinders in BMW 325e, 325es, 325i, and 325is
  • Restores proper brake fluid pressure and pedal feel
  • Addresses brake fluid leaks caused by damaged seals or bore wear
  • Improves brake system reliability and safety
  • Suitable for brake system rebuilds requiring OEM-spec master cylinder

Installation Notes and Tips

Installation requires removal of the old master cylinder and careful alignment of the two mounting holes. Since mounting hardware is not included, ensure you have the correct bolts and tools on hand. The plastic reservoir must be sourced separately if needed. Proper bleeding of the brake system after installation is essential to remove air and ensure optimal brake performance. Verify that the outlet ports are connected with compatible M10-1.00 bubble flare fittings to prevent leaks.

Quality Assurance and Warranty

Centric Premium Brake Master Cylinders are manufactured to meet or exceed OEM specifications for fit and function. The cast iron construction and included gasket contribute to long-term durability and leak prevention. While specific warranty details are not provided here, Centric products typically come with a limited warranty against defects in materials and workmanship. Always consult product documentation or supplier information for exact warranty terms.
