Detailed Description
Centric Premium Brake Master Cylinders are engineered to match original equipment parts in quality, configuration, and fitment. This master cylinder uses a cast iron housing, an integral reservoir style, and a 1-1/8 in. bore to support proper hydraulic response in the brake system. The unit includes the reservoir, cap, dust boot, and push rod, while mounting hardware is not included.
Use this brake master cylinder when replacing a worn or leaking hydraulic unit on vehicles that call for the same OE-style layout. The 130.66001 is a direct-fit brake hydraulics replacement for applications including Honda Civic and Toyota Corolla, where correct outlet thread size, bore diameter, and reservoir style are critical for service accuracy. This part cross-references Dorman First Stop M21680 for the same application.
Common Problems This Part Can Help Address
- Low or inconsistent brake pedal pressure
- Brake fluid leakage from the master cylinder body or seals
- Pedal travel that feels excessive or soft
- Hydraulic brake response issues caused by internal wear
- Replacement needs after corrosion or reservoir damage
Installation Notes and Tips
Verify bore diameter, outlet thread size, flare type, and reservoir style before installation. Bench bleed the master cylinder before connecting brake lines to help remove trapped air from the hydraulic circuit. Inspect the brake booster push rod contact point, brake fluid condition, and line fittings during service. Because mounting hardware is not included, reuse or source the correct fasteners as needed.
Quality Assurance
Centric’s brake hydraulic program is built around OE-style replacement standards for quality, configuration, and fitment. The 130.66001 master cylinder is produced to align with original equipment specifications for the listed brake hydraulic application.
