Additional Notes
- The Caterpillar 825C (serial prefix 86X) and 826C (serial prefix 87X) soil compactors both carry a brake fluid capacity of 2.6 liters, applying to the hydraulic brake system under normal use conditions.
- A 2.6-liter capacity in a hydraulic brake system of this class reflects the volume required to fill the master cylinder reservoir, brake lines, and actuating components throughout the circuit.
- The serial prefix designations 86X and 87X serve as production identifiers, confirming that the 2.6-liter specification applies across units built within the 1978-1995 model range for each respective machine.
- Both the 825C and 826C share an identical 2.6-liter brake fluid capacity, indicating that despite being distinct compactor models, the hydraulic brake circuit architecture between the two was dimensionally equivalent during the covered production period.
