Genuine VW/Audi 113611053BI Rear Drum Brake Wheel Cylinder

The Genuine VW/Audi 113611053BI Wheel Cylinder is an OEM replacement component designed for drum brake systems on classic Volkswagen and Audi vehicles. This hydraulic brake component ensures reliable stopping power by converting hydraulic pressure into mechanical force.

Key Features:

• Genuine OEM Volkswagen/Audi quality and fitment
• Hydraulic cylinder design pushes brake shoes against drum surface
• Includes pre-installed bleeder screw for brake system bleeding
• Sealed pistons with boots to prevent dirt and debris contamination
• Precision-engineered bore diameter for proper brake shoe actuation
• Direct replacement for worn or leaking wheel cylinders

The wheel cylinder uses hydraulic brake fluid pressure to extend pistons on both sides, pressing the brake shoes against the inside of the brake drum to create the friction needed to slow and stop the wheel. This genuine component is manufactured to Volkswagen/Audi specifications for reliable performance and long service life. Replacement is recommended when experiencing brake fluid leaks, spongy brake pedal feel, or reduced braking effectiveness.
