1. Servicing Precautions
Bleeding (removing air from hydraulic lines)
may be done exactly the same as a non-ABS equipped vehicle
or may have specific bleeding procedures
when disconnecting brake lines, accumulator pressure may have to be relieved – can be up to 2800 PSI!
read manufacturer's instructions carefully before beginning repairs!
ABS problem: always begin with a thorough inspection of the base brake system (non-ABS portion) first
brake warning light indicates a problem in the base braking system – not the ABS
ABS warning lamp indicates a problem within the ABS

2. Warning Lights
both brake warning lights should come on when the ignition is turned on
this confirms that the warning circuit is operational

3. Service Tips check wheel speed sensors for debris build-up
check tone rings for damage/debris
check sensor wiring & connectors
mismatched tire sizes confuses EBCM

4. Service Tips
do NOT push caliper pistons in without loosening bleeder screw
this prevents dirt from being pushed out of the caliper & into the modulator
regular brake fluid flushes (every 2 years) will minimize modulator & solenoid problems & extend their life span
