Additional Notes

  • The JCB Fastrac 125 Series carries a brake fluid capacity of 0.75 liter in each hydraulic brake circuit, with separate front and rear systems each holding that same volume.
  • The front and rear hydraulic brake systems are specified independently, meaning each circuit holds its own 0.75 liter fill rather than sharing a combined reservoir across both axles.
  • A check interval of 10 hours applies to both the front and rear hydraulic brake systems, reflecting the demanding operating environment typical of agricultural machinery where fluid condition and level can shift rapidly under load.
  • The change interval is set at 2000 hours or 24 months, whichever comes first, and applies equally to the front and rear brake circuits across both serial number ranges covered by the 1991-1997 production span.
  • Two distinct serial number ranges are covered in the specifications: units up to serial number 636.000 and units from serial number 636.001 onward, though both ranges share identical capacity and interval figures for the brake fluid system.
