Product Details

The ACDelco 18M2560B is an ACDelco Professional brake master cylinder assembly, engineered as a high-quality replacement for the original equipment brake master cylinder on select GM vehicles. Designed with the same precision and durability expected from an OE supplier, this master cylinder delivers confident, reliable braking performance.

Key Features:

  • Dual-material construction: Utilizes both aluminum and iron castings for strength and reduced weight
  • EPDM and SBR rubber components: Ethylene Propylene (EPDM) and Styrene Butadiene (SBR) seals provide superior resistance to heat, corrosion, and fluid leakage
  • Pressure tested: Each unit is pressure tested prior to packaging to ensure safe, leak-free operation
  • SAE J1153 / J1154 compliant: Meets brake performance requirements of SAE J1153 and J1154 testing standards
  • Ready to install: Arrives pre-filled and ready to bench bleed — no additional assembly required
  • Precise fit: Geometric tolerances ensure the body and plastic reservoir mate correctly for a proper, secure fit

The ACDelco 18M2560B is manufactured to meet OE fit, form, and function requirements, making it a direct replacement that installs without modification. Backed by ACDelco's reputation as a GM-trusted parts supplier, this master cylinder is a dependable choice for restoring full brake system integrity.

Ordered Enkei brand hubcentric rings, company sends Coyote brand hubcentric rings. Will they work, yes but it's a classic bait-n-switch sales tactic. Wish THMotorsports was upfront & honest with their customers.

Easy to locate parts needed, just had issue finding mounting hardware.

I had good experience, received the product as expected, reasonably priced.

Shipped right away and arrived in good condition!
