Detailed Description
The MPA Electrical M1398 brake master cylinder is engineered for Cadillac DeVille and Cadillac Fleetwood models from 1968 through 1970 that use front disc brakes. It features an integral reservoir, cast iron body, and 1-inch bore diameter to match the hydraulic requirements of the application. This remanufactured unit is a direct brake hydraulics replacement for drivers servicing a classic Cadillac braking system.
Because the master cylinder is a critical hydraulic component, correct bore size, reservoir configuration, and fluid compatibility matter. M1398 is built for DOT 3 brake fluid and includes the master cylinder cap, while omitting unrelated components such as a booster, push rod, sensor, or mounting bracket.
This part cross-references Monroe Shocks & Struts (e.g., 5463792) for the same application.
What It Helps Solve
- Low or inconsistent brake pedal feel
- Internal hydraulic leakage in the master cylinder
- Brake fluid loss at the master cylinder assembly
- Reduced braking response in front disc brake systems
- Brake service needs on classic Cadillac DeVille and Fleetwood models
Installation Notes and Tips
Before installation, verify the vehicle is equipped with front disc brakes and confirm the bore size and mounting pattern match the original unit. Bench bleeding the master cylinder before final installation helps remove trapped air from the hydraulic circuit. Inspect brake lines, fittings, and the booster interface during service, and fill only with DOT 3 brake fluid.
Quality Assurance
MPA Electrical remanufactures this master cylinder using OE sample references and testing protocols aligned to OE specifications. Each unit is checked to help ensure consistent hydraulic performance out of the box.
