Austin A55

Brake fluid capacity & service interval

Austin A55 brake fluid capacity ranges between min and max. Service intervals occur every 1500 km. Data covers 3 configurations.

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

Additional Notes

  • The Austin A55 brake fluid level specification is expressed as a range rather than a fixed volume, with the reservoir kept between a minimum and maximum mark rather than filled to a precise capacity figure.
  • A check interval of 1500 km applies to all three A55 variants across the 1957-1961 production span, covering the Cambridge Mk I, Cambridge Mk II, and Countryman body styles.
  • All three variants share an identical service interval of 1500 km under normal use conditions, with no variation between the earlier Cambridge Mk I and the later Mk II or Countryman configurations.
  • The hydraulic brake system noted across all A55 variants means brake fluid serves as the pressure-transmitting medium, making reservoir level a direct indicator of system integrity rather than a routine consumption figure.
  • The min-to-max fill specification is consistent across the Cambridge Mk I covering 1957-1958, the Cambridge Mk II covering 1959-1961, and the Countryman covering 1960-1961, with no variant calling for a different reservoir fill range.
