Hyundai Bayon, BC3 (EU)
Brake fluid capacity & service interval
Hyundai Bayon, BC3 (EU) uses brake fluid with a capacity between min and max. Service intervals include checks at 15000 km or 12 months and changes at 30000 km or 24 months. The data covers 2 configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.
| Type | Specifications |
|---|---|
| Bayon 1.0 T-GDI (74 kW) 48V-Hybrid (2020- ) |
|
| Bayon 1.0 T-GDI (88 kW) 48V-Hybrid (2020-2024) |

Additional Notes
- The brake fluid capacity for both the 74 kW and 88 kW 48V-Hybrid variants of the Hyundai Bayon BC3 is expressed as a range rather than a fixed volume, with the correct level falling between the reservoir's minimum and maximum marks. A level expressed this way reflects a service fill reference rather than a measured overhaul quantity.
- The check interval for the hydraulic brake system is set at 15,000 km or 12 months under normal use conditions, whichever comes first. An annual check interval is common for brake fluid because the fluid absorbs moisture over time, which lowers its boiling point and can affect braking performance.
- The change interval is specified at 30,000 km or 24 months under normal use conditions. The 24-month ceiling reflects the hygroscopic nature of brake fluid, where moisture absorption accumulates regardless of mileage driven.
- Both the 74 kW and 88 kW 48V-Hybrid configurations share identical check and change intervals, as well as the same level-based capacity specification, indicating no differentiation in brake fluid servicing between the two power outputs.
- The check interval of 15,000 km or 12 months and the change interval of 30,000 km or 24 months follow a consistent 2:1 ratio in both distance and time, meaning one fluid change is expected for every two inspection points in a standard service cycle.
