Description
xAA Ignition’s Replacement Brake Master Cylinder is designed to restore the hydraulic heart of your braking system. When you press the pedal, a rod actuates pistons inside the master cylinder, creating hydraulic pressure that pushes brake fluid through the lines. This flow helps the calipers grip the rotors, delivering controlled stopping power you can feel at the pedal and through the wheels.
Compatibility matters. This unit fits a range of GM trucks and SUVs from the 1999–2002 era, including Silverado 1500, Sierra 1500, Suburban 1500, Blazer, Tahoe, Yukon, and Escalade variants, across multiple model years. It replaces several OEM numbers, offering a direct replacement that mirrors the factory geometry and mounting points.
What you get with this replacement
- OEM-style fit and direct replacement to factory mounting and port locations
- Replaces part numbers M630031, 18040252, 18048538, 18060789, 19209249

The part is designed to be located beneath the brake fluid reservoir and near the top of the braking system, simplifying inspection and replacement. Its installation supports the same hydraulic pathway as the original, helping to restore predictable pedal feel when driving under typical conditions.
Quality and performance notes. While this part is intended as a direct replacement, outcomes depend on the overall condition of the braking system, including hoses, lines, and calipers. Regular maintenance remains important. The unit is engineered to withstand everyday driving pressures and to deliver stable hydraulic flow through the life of the brake system when properly installed.
