Functional Test

If determined that difficulty is in the Sure Track Brake System, engine idle speed, vacuum level and standard brake system must be verified to be within limits of service specifications before proceeding with standard testing.

The following test of anti-skid control and hydraulic system will determine if system is operating and should be made after repairs, to verify correct system operation.

1. Turn ignition key ON. Listen for solenoid click and actuator cycling sound.
2. Position vehicle on hoist and raise rear wheels to clear floor. Start engine and warm up until normal operating temperature is reached.
3. Place transmission in DRIVE, and accelerate to approximately 25-30 MPH.
4. Apply brakes quickly and firmly and observe rear wheels. If Sure Track Brake System is functioning properly, it will cycle 5 or 6 times or until brake pedal is released.
