Tires, suspension, wheel alignment and shocks can affect braking performance
and should be inspected prior to checking the braking system. Some problems and
repairs are listed below:
• Pedal fade is a good indication of leaks in the system. Inspect and
repair leaks.
• Sluggish brake response indicates air has been introduced into the
system. Bleed the brake system.
• Excessive pedal travel or excessive pedal effort relates to booster and
master cylinder.
• Booster doesn't function properly in power or back-up mode. Repair
the booster and pump assembly.
• Booster works only in the back up mode. Repair the booster assembly.
• Booster works only in the power mode. Repair the back-up pump.
• Dragging, grabbing, squealing or pulling brakes require servicing pads
and calipers.
The Hydraulic Antilock Braking System is an electronic wheel speed monitoring
and control system. The Electronic Control Unit (ECU) receives and processes
signals sent from the wheel sensors located on each of the wheels. The ECU will
process the signals and generate the commands to the solenoid control valves
housed in the Modulator Assembly used to control the brake pressure. This process
occurs when the wheels begin to lock. The rapid valve operations may be felt in
the brake pedal.
The ABS indicator light located on the dash will alert the driver to possible
system faults and is used by service personnel to assist in troubleshooting. In the
event the ABS indicator light remains illuminated, normal braking is not affected.
However, the ABS system may not function correctly in a panic stop. It is
recommended to drive with caution and obtain service on the ABS system as soon
as possible.
