Detailed Description

MPA Electrical NM55298 is a brake master cylinder designed to restore hydraulic braking performance on 2003-2008 Toyota Corolla, Toyota Matrix, and Pontiac Vibe models equipped with front disc brakes. It is manufactured as a new standard replacement unit and tested against OE specifications using sample-based validation and controlled inspection processes. The aluminum master cylinder body, 0.8125 bore diameter, and included plastic reservoir support consistent brake pressure delivery and fluid management for the listed applications.

This part cross-references Toyota and related OE numbers such as 472011A360 and 4720102240 for the same application. If you are replacing a worn or leaking master cylinder on a Toyota Corolla, Matrix, or Pontiac Vibe, NM55298 provides the core hydraulic components needed for a proper brake system repair.

Common Issues This Part Can Address

• Low or sinking brake pedal feel
• Brake fluid leakage at the master cylinder
• Uneven or inconsistent hydraulic pressure
• Internal seal wear causing reduced braking response
• Brake warning symptoms tied to master cylinder failure

Installation Notes and Tips

• Verify vehicle fitment by year, make, model, and front disc brake configuration before installation.
• Bench bleed the master cylinder before connecting brake lines to reduce trapped air in the system.
• Use only DOT 3 brake fluid as specified.
• Mounting hardware, brake booster, push rod, sensor, and pressure switch are not included.
• Inspect brake lines, fittings, and the booster condition during replacement to avoid repeat hydraulic issues.

Quality Assurance

MPA Electrical uses an OE sample library and proprietary test procedures to check each unit against original equipment specifications. That process helps ensure the NM55298 brake master cylinder is ready for consistent braking performance after installation.
