Additional Notes

  • Across all listed configurations of the Mercedes-Benz GLA-Class X156, the hydraulic brake system holds a capacity of 0.5 liter, which represents the total fluid volume for a service fill of the brake reservoir rather than a full system overhaul figure.
  • The 24-month change interval applies under normal use conditions for every variant in the specifications, meaning the interval is tied to calendar time rather than mileage accumulation.
  • The GLA 250 (156.944) and GLA 250 4MATIC (156.946) share identical brake fluid capacity and change interval specifications across their 2014-2020 production span.
  • The GLA 45 AMG 4MATIC (156.952) appears under two separate year ranges, 2014-2015 and 2015-2020, yet both entries carry the same 0.5 liter capacity and 24-month service interval under normal use conditions.
  • The 0.5 liter capacity figure is consistent across both the standard GLA 250 variants and the higher-performance GLA 45 AMG 4MATIC, indicating no difference in reservoir volume between those configurations.
