Product Details

MPA Electrical’s New with front disc brakes product line focuses on direct-fit brake hydraulic replacement parts for vehicles that require the correct OE-style configuration. NM55585 is engineered to restore braking performance by matching OE specifications through tested manufacturing processes and controlled inspection protocols. This brake master cylinder is intended for Mercedes-Benz platforms where a 1.0-inch bore and aluminum construction are required for proper hydraulic operation.

This part cross-references Mercedes-Benz OE numbers 0064301301 and 0064301701 for the same application.

What It Helps Fix

• Low or inconsistent brake pedal feel
• Internal master cylinder seal wear
• Brake fluid bypass inside the hydraulic system
• Reduced braking response from a failing hydraulic unit
• Brake warning symptoms tied to master cylinder performance

Installation Notes

Reservoir, cap, push rod, brake booster, mounting bracket, mounting hardware, sensor, and brake pressure switch are not included. Verify bore diameter, mounting hole size, and vehicle brake configuration before installation. Proper bleeding of the brake system is required after replacement, and all hydraulic connections should be inspected for leaks.

Quality Assurance

Each NM55585 master cylinder is tested against OE specifications using MPA Electrical’s proprietary processes and strict inspection protocols to help ensure consistent braking performance out of the box.
