Detailed Description

MPA Electrical NM52473 is a brake master cylinder for front disc brake vehicles that need a direct replacement hydraulic component. Using OE sample references and testing protocols against OE specifications, this unit is built to restore braking performance and deliver consistent operation after installation. It is a direct-fit choice for 1989-1990 Chevrolet Tracker, 1989-1990 Geo Tracker, 1989-1990 GMC Tracker, and 1989-1990 Suzuki Sidekick models with front disc brakes. This part cross-references 5110060A30 and 96058714 for the same application.

What It Helps Fix

  • Low or inconsistent brake pedal feel
  • Internal master cylinder seal wear
  • Brake fluid leakage at the master cylinder
  • Reduced hydraulic pressure to the brake system
  • Brake performance loss on front disc brake vehicles

Installation Notes and Tips

Verify the bore diameter, mounting hole layout, and reservoir configuration before installation. Use DOT 3 brake fluid only, and bleed the hydraulic system thoroughly after replacement to remove trapped air. Confirm that the vehicle is equipped with front disc brakes and match the application to the listed Tracker and Sidekick fitment before final assembly.

Quality Assurance

MPA Electrical tests each brake master cylinder against OE specifications using controlled processes and strict inspection protocols to support consistent braking performance out of the box.
