PGO T-Rex

Brake fluid capacity & service interval

PGO T-Rex uses brake fluid with a capacity range of min to max. The service interval is 24 months. The data covers 3 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

TypeSpecifications
T-Rex 125 (2006-2008)
  • Use: Normal
  • Between min and max.
  • Change 24 months
T-Rex 50 (2006- )
  • Use: Normal
  • Between min and max.
  • Change 24 months
T-Rex 150 (2004-2008)
  • Use: Normal
  • Between min and max.
  • Change 24 months

Additional Notes

  • The PGO T-Rex brake fluid reservoir fill level applies to a hydraulic brake system, meaning the fluid operates under pressure to actuate the brakes rather than relying on a mechanical cable linkage.
  • Across the T-Rex 125, T-Rex 150, and T-Rex 50 configurations, the specified fill level is between the minimum and maximum marks on the reservoir, which is a standard service fill indicator rather than a measured volumetric capacity.
  • The T-Rex 150 carries the earliest model year coverage in the data, with specifications beginning in 2004, while the T-Rex 125 and T-Rex 50 both have specifications beginning in 2006.
  • All three configurations share an identical 24-month change interval under normal use conditions, meaning the fluid is due for replacement on a time-based schedule regardless of mileage accumulated within that period.
  • Brake fluid absorbs moisture over time, which lowers its boiling point and can compromise hydraulic performance, making the 24-month interval a reflection of fluid degradation rather than mechanical wear.
