Brake fluid capacity & service interval

Boss Hoss Trike uses brake fluid with a capacity range of min to max. Service intervals include normal use. The data covers 2 configurations.

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

TypeSpecifications
BHC-9 LS2 Trike (2007- )
  • Use: Normal
  • Between min and max.
BHC-9 ZZ4 Trike (2007- )
  • Use: Normal
  • Between min and max.

Additional Notes

  • Both the Boss Hoss BHC-9 LS2 Trike and the BHC-9 ZZ4 Trike share the same brake fluid fill specification: the hydraulic brake system reservoir is to be filled between the minimum and maximum marks.
  • The "between min and max" specification is a level-based fill guideline rather than a fixed volumetric capacity, meaning the correct fill amount is determined by the reservoir's marked indicators rather than a measured quantity in liters or ounces.
  • Both configurations are identified as hydraulic brake systems, which rely on fluid pressure transmitted through lines to actuate the braking components at each wheel or axle end.
  • The LS2 and ZZ4 variants represent two distinct engine configurations within the BHC-9 Trike lineup, yet both share identical brake fluid level specifications under normal use conditions, indicating no engine-driven variation in the brake system fill requirement.
