Additional Notes

  • The Jeep Wrangler / CJ-7 / CJ-8, YJ brake fluid capacity of 0.4 liter for the CJ-7 / CJ-8 (USA) across 1985-1987 reflects a service fill volume, representing the amount of fluid held within the hydraulic brake system under normal operating conditions.
  • The 0.4 liter figure is specific to the hydraulic brake system, which encompasses the master cylinder reservoir along with the lines, calipers, and wheel cylinders that together form the complete brake circuit.
  • A capacity as modest as 0.4 liter is consistent with what is typically found in compact hydraulic brake circuits of that era, where reservoir volume was kept small relative to the overall system demand.
