Bleeding the ABS System

WARNING: This page is about a different car, the 2003 Pontiac Grand Prix. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: Refer to BRAKE FLUID IRRITANT CAUTION .

Perform a manual or pressure bleeding procedure. Refer to MANUAL BLEEDING or PRESSURE BLEEDING . If the desired brake pedal height results are not achieved, perform the automated bleed procedure below.

The procedure cycles the system valves and runs the pump in order to purge the air from the secondary circuits normally closed off during normal base brake operation and bleeding. The automated bleed procedure is recommended when air ingestion is suspected in the secondary circuits, or when the BPMV has been replaced.
