Detailed Description

MPA Electrical NM4353 is a brake master cylinder for Cadillac ATS and Cadillac CTS models equipped with front disc brakes. It is built to restore hydraulic pressure transfer from the brake pedal to the brake system, helping maintain firm pedal feel and predictable braking response. The aluminum housing and OE-based testing process support consistent fit and function for the listed applications. This part cross-references 541-01373 and 23198885 for the same application.

Common Brake Issues It Can Address

  • Low or inconsistent brake pedal feel
  • Internal hydraulic leakage in the master cylinder
  • Brake pedal travel that increases over time
  • Reduced braking response from worn hydraulic components
  • Fluid seepage around the master cylinder seals

Installation Notes and Tips

Verify vehicle fitment by year, make, model, and front disc brake configuration before installation. This master cylinder does not include a reservoir, brake booster, push rod, mounting hardware, or cap, so reuse or source those components as needed for the application. Bench bleeding the master cylinder before installation helps reduce trapped air in the hydraulic system, and the brake system should be bled thoroughly after installation with DOT 3 brake fluid.

Quality Assurance

MPA Electrical uses OE sample references and strict testing protocols to verify brake master cylinder performance against OE specifications. NM4353 is a new standard replacement part built for the listed Cadillac ATS and Cadillac CTS applications.
