R-Line Wheel Cylinder Cup, Raybestos, WCC2502, Fits: 1963 American Motors American Front

Drum Brake Wheel Cylinder Cup is a precision-engineered replacement component designed to restore and maintain the integrity of your vehicle’s hydraulic drum brake system. Crafted from high-quality, durable materials, this cup provides a reliable seal within the wheel cylinder, ensuring optimal hydraulic pressure and smooth piston movement for consistent braking performance.

• OE‑matched design: The cup is designed to reflect original‑equipment geometry, meaning correct dimensions, shape, and rubber hardness and durability.
• High‑quality sealing material: The rubber cup (seal) inside should resist brake fluid, heat, moisture, and corrosion  to maintain integrity under operating conditions.
• Durability and longevity: Because the cup is the seal keeping high‑pressure hydraulic fluid contained, it must resist wear, deformation, and aging over many cycles.
• Corrosion and contamination resistance: Given that drums, wheels, and brake assemblies are exposed to water, salt, dust, and varying temperatures.
