Antilock Brake System Bleeding
For brake fluid type. Refer to CAPACITIES AND RECOMMENDED FLUIDS, SPECIFICATIONS .
The base brake's hydraulic system must be bled anytime air enters the hydraulic system. The Antilock Brake System (ABS) must always be bled anytime it is suspected that the Hydraulic Control Unit (HCU) has ingested air.
Brake systems with ABS must be bled as two independent braking systems. The non-ABS portion of the brake system with ABS is to be bled the same as any non-ABS system.
The ABS portion of the brake system must be bled separately. Use the following procedure to properly bleed the brake hydraulic system including the ABS.
During the brake bleeding procedure, be sure the brake fluid level remains close to the FULL level in the master cylinder fluid reservoir. Check the fluid level periodically during the bleeding procedure and add brake fluid as required.
