Additional Notes

  • The JCB Fastrac 135 Series carries a brake fluid capacity of 0.75 liter for each hydraulic brake circuit, with front and rear systems each holding that same volume as separate fills.
  • Both the front and rear hydraulic brake systems share identical service intervals, requiring a fluid check every 10 hours of operation and a full fluid change at 2000 hours or 24 months, whichever comes first.
  • The 24-month time limit on the change interval runs alongside the 2000-hour threshold, meaning calendar time alone can trigger a fluid change even when hour accumulation has not reached the operational limit.
  • Specifications are divided across two serial number bands: units up to serial number 636.000 and units from serial number 636.001 onward, both covering the 1991-1997 production period.
  • Despite the split between the two serial number bands, the capacity and service interval figures are consistent across all four rows, with 0.75 liter, a 10-hour check, and a 2000-hour or 24-month change applying equally to both bands and both axle positions.
  • The 10-hour check interval is notably short relative to the 2000-hour change interval, reflecting the safety-critical nature of hydraulic brake fluid monitoring in high-use agricultural machinery.
