  • ATE part number 020003 for direct catalog identification

Product Details

This ATE drum brake wheel cylinder is engineered for the hydraulic side of a drum brake system, where internal sealing and bore condition affect brake response. The aluminum body helps limit corrosion in the presence of moisture and brake fluid, supporting consistent operation over time. If you are servicing Volkswagen or Audi rear drum brake components, ATE 020003 provides a focused replacement option for brake hydraulic maintenance. This part cross-references 8AW 355 531-261 for the same application.

Common Problems It Can Address

  • Brake fluid seepage at the wheel cylinder
  • Corrosion inside the drum brake hydraulic assembly
  • Uneven rear brake performance from a worn cylinder
  • Soft or inconsistent brake pedal feel caused by hydraulic wear
  • Brake service needs on drum brake rear systems

Installation Notes and Tips

Inspect the brake shoes, drums, and hydraulic lines before installation. Clean the backing plate area, verify the cylinder seats correctly, and bleed the brake system after replacement to remove air from the hydraulic circuit. Mounting hardware is not included.

Quality Assurance
