Product Details

MPA Electrical NM4194 is built for vehicles equipped with front disc brakes and is listed for 2007-2008 Cadillac Escalade, Escalade ESV, and Escalade EXT; Chevrolet Avalanche, Cheyenne, Silverado 1500, Suburban 1500, and Tahoe; and GMC Sierra 1500, Yukon, and Yukon XL 1500. The master cylinder uses a 1.25-inch bore to support hydraulic brake pressure, while the aluminum housing and plastic reservoir provide a direct replacement format for service work. This part cross-references OE numbers 1943294 and 15821794 for the same application.

What It Helps Fix

  • Low or inconsistent brake pedal response
  • Internal hydraulic leakage in the master cylinder
  • Brake fluid loss at the reservoir or seals
  • Soft pedal feel caused by worn master cylinder components
  • Brake performance decline on front disc brake systems

Installation Notes and Tips

Verify vehicle fitment by year, make, model, and brake configuration before installation. This NM4194 master cylinder is supplied without mounting hardware, brake booster, push rod, sensor, or brake pressure switch. Bench bleeding the master cylinder before installation and using fresh DOT 3 brake fluid helps reduce trapped air in the hydraulic system.

Quality Assurance

MPA Electrical tests each brake master cylinder against OE specifications using controlled procedures and sample-based validation to support consistent braking performance out of the box.
