Additional Notes
- The Mercedes-Benz CLA-Class C117/X117 brake fluid capacity is 0.5 liter across all listed configurations, which is a typical service fill volume for a hydraulic brake system reservoir rather than a full system overhaul quantity.
- Every configuration in the 2013-2018 range carries a 24-month change interval under normal use conditions, meaning the fluid replacement schedule is tied to elapsed time rather than mileage.
- The CLA 250 in both rear-wheel-drive form (117.344/944) and 4MATIC all-wheel-drive form (117.346/351/949/951) shares the same 0.5-liter capacity and 24-month interval, indicating no variation between drivetrain configurations for brake fluid service.
- The CLA 45 AMG 4MATIC (117.352) appears across two overlapping specification entries: one covering 2013-2015 and another covering 2015-2018, with both entries specifying identical values of 0.5 liter and a 24-month change interval.
- The 2015-2018 CLA 45 AMG 4MATIC entry adds chassis code 117.952 alongside 117.352, reflecting the inclusion of an additional variant within the same generation while retaining the same brake fluid specifications.
- The consistent 0.5-liter figure across all four rows suggests the hydraulic brake system reservoir size does not differ between the standard CLA 250 and the higher-performance CLA 45 AMG despite differences in engine output and braking demands.
