Brake Master Cylinder Reservoir Cap

Brake Master Cylinder Reservoir Cap

This brake master cylinder reservoir cap is designed to seal the brake fluid reservoir and help maintain a clean, closed brake system. It prevents contamination, moisture intrusion, and fluid loss, which are critical for preserving proper brake pressure and reliable pedal feel.

While this reservoir cap is compatible with many older Honda vehicles, it is known to fit most 1996–2000 Honda Civic and 1994–2001 Acura Integra applications. However, due to variations in brake reservoir designs across years and trims, there is a possibility it may not fit every Civic or Integra without verifying the specific reservoir configuration. Confirm fitment with your exact model and brake assembly before installation.
