Detailed Description

This brake master cylinder is engineered for Mazda RX-7 braking systems that require a remanufactured hydraulic replacement with front disc brakes. The cast iron construction and 0.875-inch bore support proper brake pressure generation, while the standard replacement design helps return the system to normal pedal operation. If you are servicing a 1986, 1987, or 1988 Mazda RX-7, M52216 provides a direct-fit hydraulic component for the brake system.

This part cross-references Monroe Shocks & Struts (e.g., FB0843400C) for the same application.

What It Helps Fix

• Low or inconsistent brake pedal feel
• Brake fluid pressure loss in the hydraulic system
• Internal master cylinder wear affecting braking response
• Brake performance issues on front disc brake RX-7 applications
• Replacement needs after master cylinder leakage or failure

Installation Notes and Tips

Before installation, verify the vehicle is a 1986-1988 Mazda RX-7 with front disc brakes and confirm the bore size and mounting pattern match the original unit. Transfer any required external components from the existing system, since the reservoir, cap, push rod, dust boot, seals, and mounting hardware are not included. Bleed the brake system thoroughly with DOT 3 fluid after installation to remove air and restore firm pedal operation.

Quality Assurance

MPA Electrical remanufactures brake master cylinders using OE sample references and testing protocols aligned to OE specifications. Each unit is checked to support consistent braking performance out of the box.
