Caterpillar Articulated dump trucks
Brake fluid capacity & service interval
Caterpillar Articulated dump trucks utilize brake fluid with a capacity range of 1,2 to 10 liters. The data covers 3 configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.
| Type | Specifications |
|---|---|
| D400D, 8TF (1993-1996) |
|
| D250B, 5WD |
|
| D400, 1MD |

Additional Notes
- The Caterpillar D250B (5WD) hydraulic brake system carries a capacity range of 2.55 to 3.83 liters under normal use conditions, which indicates a variable fill volume likely dependent on the specific circuit or component being serviced.
- The D400 (1MD) hydraulic brake system holds a notably larger capacity of 10 liters under normal use conditions, reflecting the scale of braking infrastructure typical in heavier articulated dump truck configurations.
- The D400D (8TF), covering the 1993-1996 model years, lists a front hydraulic brake system capacity of 1.2 liters under normal use conditions, representing only the front circuit rather than the full system volume.
- The front-only designation on the D400D (8TF) specification suggests the braking system is divided into discrete circuits, with the 1.2-liter figure applying exclusively to the front portion of the hydraulic brake system.
- A capacity range such as the 2.55 to 3.83 liters on the D250B (5WD) is commonly associated with service fills where the exact volume depends on how much residual fluid remains in the system, rather than a fixed overhaul capacity.
- The 10-liter capacity recorded for the D400 (1MD) stands as the largest brake fluid volume across the three configurations listed, pointing to a substantially more extensive hydraulic brake circuit in that truck variant.
