For 1990-2009 cars only

    Notice: Do not use fluid that has a petroleum base. Do not use a container that has been used for petroleum based fluids or is wet with water. Petroleum-based fluids cause swelling and distortion of rubber parts in the hydraulic brake system and water lowers the brake fluid's boiling point. Keep all fluid containers capped to prevent contamination.

  1. Clean the reservoir cover and caps in order to prevent dirt from entering the hydraulic system.
  2. Remove the reservoir caps with diaphragms.
  3. Fill the reservoir to the full mark.
  4. Replace the caps with diaphragms.
