MPA Electrical NM52541 Brake Master Cylinder

Brake Master Cylinder for OE-Style Replacement

MPA Electrical NM52541 is a new brake master cylinder built for standard replacement service on vehicles with front disc brakes. It is engineered to restore hydraulic braking performance with an aluminum body, integrated reservoir, and a 0.9375-inch bore for consistent pedal response.

For buyers searching for a brake master cylinder for front disc brake applications, NM52541 is a direct-fit style hydraulic component built to OE specifications and tested against strict protocols before release.

Detailed Description

MPA Electrical NM52541 is a brake master cylinder intended for hydraulic brake system restoration where front disc brakes are used. The aluminum housing helps keep weight down while maintaining the rigidity needed for stable brake pressure delivery. With a 0.9375-inch bore, this unit is sized to match the hydraulic requirements of the application and support predictable pedal feel.

MPA Electrical uses OE sample data and testing protocols to verify each master cylinder against original specifications, helping ensure consistent braking performance out of the box. The included reservoir, cap, and seal simplify replacement of the hydraulic core, while the standard replacement design makes NM52541 a practical choice for service work on vehicles such as Honda Civic and Toyota Corolla applications where the correct master cylinder specification is critical. This part number, NM52541, is also a useful search term when sourcing a brake master cylinder for front disc brake vehicles.

What It Helps Address

• Low or inconsistent brake pedal response
• Internal hydraulic leakage in the master cylinder
• Brake fluid loss at the cylinder body or seal area
• Reduced braking performance from worn hydraulic components
• Restoration needs on front disc brake brake systems

Installation Notes and Tips

Before installation, confirm bore size, mounting hole spacing, and reservoir style match the original unit. Bench bleeding is recommended before connecting brake lines to reduce trapped air in the hydraulic system. Use clean DOT 3 brake fluid only, and inspect the brake booster, lines, and wheel circuits for contamination or leaks before returning the vehicle to service. Because mounting hardware and push rod are not included, reuse or source those components separately as required by the vehicle.

Quality Assurance

Each MPA Electrical master cylinder is tested against OE specifications using controlled inspection and validation processes. That approach supports consistent hydraulic performance and dimensional accuracy for replacement service. If you are cross-shopping NM52541, verify the application details carefully before ordering; this part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
