Service procedures

FL and RR Brake Bleed

The Electronic Stability Program (ESP) Hydraulic Control Unit executes the brake fluid flush and bleed process. Active-circuit wheels are Front-Left (FL) and Rear-Right (RR). Use this routine only during fluid flush or bleed with appropriate brake bleeding equipment. The estimated time to complete is five seconds. The ESP Hydraulic Control Unit will run the high pressure pump and control circuit valves to facilitate a prescheduled brake fluid flush or bleed.
