Product Details

The ACDelco 18M2397B is a Gold-series brake master cylinder assembly engineered as a premium replacement for hydraulic brake systems. Built with both aluminum and iron castings, this master cylinder delivers the structural integrity and dimensional accuracy needed for dependable, long-term braking performance.

ACDelco's Gold line represents high-quality OE-alternative parts designed to meet or exceed original equipment standards for fit, form, and function. This unit arrives pre-assembled and bench-bleed ready — no additional preparation or assembly is required before installation.

Key Features:

  • Aluminum and iron casting construction for strength and durability
  • EPDM (Ethylene Propylene) and SBR (Styrene Butadiene) rubber internal components for superior heat, corrosion, and leak resistance
  • Meets SAE J1153 and J1154 brake performance testing standards
  • Pressure tested to ensure safe and reliable braking
  • Geometrical tolerances ensure proper body-to-reservoir fit
  • Piston assembly and return spring help prevent brake drag and premature pad wear
  • Ready to bench bleed and install — no assembly required
  • OEM cross-reference: 19295627

Backed by ACDelco's 24-Month/Unlimited Mile Limited Warranty, the 18M2397B is a trusted solution for restoring your vehicle's brake hydraulic system to factory specification performance.

I've had nothing but oof experiences doing business with THMotorsports. Best price for spark plugs out of anyone else. Fastest shipping with reasonable rates.
