Bleeding the ABS System

Print

It is important to note that excessive air in the brake system will cause a soft or spongy feeling brake pedal.

The base brake's hydraulic system must be bled anytime air enters the hydraulic system. The ABS must always be bled anytime the HCU is replaced or it is suspected to have ingested air. Under most circumstances that require the bleeding of the brakes hydraulic system, only the base brake hydraulic system needs to be bled.

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 DOT 3 brake fluid as required.

The 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.

  1. Make sure all hydraulic fluid lines are installed and all fittings properly tightened.
  2.  
  3. Connect the DRB scan tool to the diagnostics connector. The diagnostic connector is located under the lower steering column cover to the left of the steering column.
  4.  
  5. Using the DRB, check to make sure the CAB does not have any fault codes stored. If it does, clear them using the DRB
    WARNING
    High pressure fluid may spray out of the system while bleeding. Wear safety glasses when bleeding the brake system. A clear tube must be attached to the bleeder screws and submerged in a clear container partially filled with clean brake fluid. Direct the flow of brake fluid away from yourself and the painted surfaces of the vehicle.

  6.  
  7. Bleed the base brake system using the standard pressure or manual bleeding procedure.
  8.  
  9. Using the DRB, select ANTILOCK BRAKES, followed by MISCELLANEOUS, then BLEED BRAKES. Follow the instructions displayed. When the scan tool displays TEST COMPLETED, disconnect the scan tool and proceed.
  10.  
  11. Bleed the base brake system a second time, as air from the HCU has been purged to the base brake hydraulics.
    NOTE
    Check brake fluid level in the reservoir periodically to prevent emptying, causing air to enter the hydraulic system.

  12.  
  13. Fill the master cylinder reservoir to the full level.
  14.  
  15. Test drive the vehicle to be sure the brakes are operating correctly and that the brake pedal does not feel spongy.
  16.  

During the brake bleeding procedure, make 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 DOT 3 brake fluid as required.

The ABS must be bled as two independent braking systems. First the base brake (non-ABS portion) of the brake system is bled in the conventional manner. Then the ABS portion of the brake system is bled using a scan tool. Finally the base brake system is re-bled. Use the following procedure to properly bleed the brake hydraulic system including the ABS.


NOTE
Before servicing the vehicle, also refer to the precautions in the beginning of this section.

To bleed the ABS system use the following bleeding sequence to insure complete and adequate bleeding.

  1. Make sure all hydraulic fluid lines are installed and properly torqued.
  2.  
  3. Connect a scan tool to the diagnostics connector. The diagnostic connector is located under the lower steering column cover to the left of the steering column.
