ACDelco 174-1268 Rear Drum Brake Wheel Cylinder

The ACDelco 174-1268 is a genuine GM rear drum brake wheel cylinder designed to restore proper braking performance on compatible vehicles. This wheel cylinder is a critical component of the drum brake system, converting hydraulic pressure from the brake master cylinder into mechanical force that pushes the brake shoes against the drum to slow or stop the vehicle.

Key Features:

• Genuine ACDelco OE quality replacement part
• Direct fit wheel cylinder for rear drum brake applications
• Manufactured to GM original equipment specifications
• Includes internal pistons, cups, and seals for complete assembly
• Engineered for reliable hydraulic sealing and consistent brake performance

This wheel cylinder assembly is designed for professional installation and should be installed in pairs (both rear wheels) to maintain balanced braking. Bleeding the brake system is required after installation to remove air and ensure proper brake operation.
