Raybestos WC37707 Rear Drum Brake Wheel Cylinder

Raybestos WC37707 Rear Drum Brake Wheel Cylinder — part of the Raybestos PG Plus Professional Grade line — is a direct-replacement hydraulic wheel cylinder for rear drum brake systems. This component converts brake fluid pressure into piston force to push the rear brake shoes against the drums, restoring braking response on applicable vehicles. It is specified for Honda Accord model years 1986–1988 with rear drum brakes, representing a common OEM replacement that matches factory fitment. The unit is designed for drum-brake assemblies and works with the backing plate, shoes, springs, and drums to reestablish hydraulic operation under regular driving conditions. Install with the correct brake fluid and torque specs to ensure a proper seal and avoid leaks. The PG Plus designation denotes a professional-grade build intended to deliver reliable performance in daily driving and light-duty service.
