• Aluminum master cylinder construction
• Uses DOT 3 brake fluid

Detailed Description

MPA Electrical M3089 is a remanufactured brake master cylinder engineered for front disc brake vehicles that need reliable hydraulic pressure at the pedal. It is compatible with 1999-2002 Chevrolet Silverado 1500, 2000-2002 Chevrolet Tahoe, 2000-2002 GMC Yukon, and other listed Cadillac, Chevrolet, and GMC models with front disc brakes. The aluminum body, 1.338-inch bore, and OE-based remanufacturing process support consistent brake system operation after installation.

This part cross-references GM OE part numbers 18040252 and 18048538 for the same application. If you are replacing a worn or leaking master cylinder on a 2002 Cadillac Escalade, 2002 Chevrolet Avalanche 1500, or 2001-2002 GMC Sierra 1500 HD, M3089 provides the correct hydraulic foundation for the brake system.

What It Helps Fix

• Low or sinking brake pedal feel
• Brake fluid leakage at the master cylinder
• Uneven or inconsistent hydraulic brake pressure
• Brake warning symptoms caused by master cylinder wear
• Reduced braking response in front disc brake systems

Installation Notes and Tips

Before installation, verify the vehicle uses front disc brakes and matches the listed fitment. This master cylinder does not include the reservoir, cap, push rod, brake booster, mounting hardware, gasket, seal, sensor, or brake pressure switch. Bench bleeding the master cylinder before installation and flushing the system with fresh DOT 3 fluid helps reduce trapped air and supports proper pedal feel.

Quality Assurance

MPA Electrical remanufactures brake master cylinders using OE sample references and testing procedures that check each unit against OE specifications. That process is used to deliver consistent braking performance out of the box for the listed Cadillac Escalade, Chevrolet Silverado 1500, and GMC Sierra 1500 applications.
