Product Details

MPA Electrical NM55026 is engineered as a brake master cylinder replacement for Toyota Celica models from 1990 through 1993 equipped with front disc brakes. The unit is tested against OE specifications using sample-based validation and controlled processes to help restore braking performance and pedal feel. The aluminum master cylinder housing and plastic reservoir are paired with a 1-inch bore for a direct hydraulic replacement in the brake system. This part cross-references Monroe Shocks & Struts (e.g., 4720120730) for the same application.

Common Brake Issues It May Address

• Low or inconsistent brake pedal response
• Internal hydraulic leakage in the master cylinder
• Brake fluid loss at the reservoir or seals
• Soft or spongy pedal feel after master cylinder wear
• Reduced braking performance on a Toyota Celica brake system

Installation Notes and Tips

Verify vehicle fitment by year, model, and front disc brake configuration before installation. Bench bleeding the master cylinder before final assembly helps remove trapped air from the hydraulic circuit. Inspect brake lines, booster condition, and fluid quality during service, and confirm all connections are clean and properly torqued after installation. Mounting hardware, push rod, brake booster, sensor, and brake pressure switch are not included.

Quality Assurance

MPA Electrical tests each brake master cylinder against OE specifications using proprietary procedures and strict protocols to support consistent braking performance out of the box. Part number NM55026 is a new standard replacement brake hydraulic component for Toyota Celica applications.
