Metelli Rear Wheel Brake Cylinder Bore

Metelli rear drum brake wheel cylinders (also called rear wheel brake cylinders or drum brake slave cylinders) are replacement parts for the rear drum brake assembly. When you press the brake pedal, hydraulic pressure pushes the cylinder's pistons outward. The pistons press the brake shoes against the drum, which slows and stops the vehicle.

Key Features:

• Cast iron cylinder body for durability under repeated brake pressure
• Made as a replacement for the original equipment rear wheel cylinder
• Piston bore diameter is matched to the application, so choose the bore size that matches your original cylinder
• Replaces worn or leaking cylinders to restore consistent rear brake response

Replacing a leaking or sticking wheel cylinder helps keep rear braking even and reliable. Brake shoes and drums are often inspected or replaced at the same time. Bleed the hydraulic system after installation.
