Detailed Description

URO GMC235 is a brake master cylinder engineered for hydraulic brake systems that require stable pressure generation and consistent pedal feel. Its precision manufacturing helps maintain the clearances needed for proper brake system operation, while the seal material is selected for compatibility with standard glycol-based brake fluid. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

  • Brake fluid leaks at the master cylinder
  • Soft or inconsistent brake pedal feel
  • Loss of hydraulic pressure in the brake system
  • Fluid contamination of carpeting or under-dash areas
  • Brake performance issues caused by internal seal wear

Installation Notes and Tips

Before installation, inspect the brake lines, reservoir, and surrounding hydraulic components for contamination or damage. Bench bleeding the master cylinder before final installation helps remove trapped air and supports proper brake pedal operation after service. Verify the vehicle application by part number and brake system configuration before ordering. Compatible With BMW 3 Series and BMW 5 Series brake hydraulic service applications.
