Cadillac Lyriq (USA / CAN)

Brake fluid capacity & service interval

Cadillac Lyriq (USA / CAN) requires brake fluid with a capacity range between min and max. The service interval for the fluid is 60 months. The data covers 4 configurations.

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

Additional Notes

  • The Cadillac Lyriq (USA / CAN) brake fluid specifications cover four configurations for the 2023 model year: the 253 kW rear-wheel-drive, the 373 kW rear-wheel-drive, the 253 kW AWD, and the 373 kW AWD variants.
  • All four configurations share an identical service interval of 60 months under normal use conditions, meaning brake fluid replacement is scheduled on a five-year cycle regardless of output level or drivetrain layout.
  • The capacity specification for each configuration is expressed as "between min and max" rather than a fixed volume, which is standard for hydraulic brake systems where the reservoir level is maintained within a marked range rather than filled to a precise measured quantity.
  • A "between min and max" fill specification indicates a top-up or inspection-based service approach, where the fluid level in the reservoir is verified against the minimum and maximum markings on the reservoir body rather than drained and refilled to a set capacity figure.
  • The 253 kW and 373 kW output ratings across both drivetrain layouts do not produce any variation in brake fluid service intervals or fill specifications, as all four rows carry the same 60-month change interval and the same reservoir-level-based capacity guidance.
