Brake Pressure Application Testing (W/JL4): Notes
IMPORTANT:
Before performing the following tests, perform all of the isolation valve tests described in the wheel isolation test procedure. A malfunctioning isolation valve may cause pressure to be applied to multiple wheels, instead of to just one wheel as commanded.
If the brake being tested fails to apply, does not hold for the full 9 second period, or releases slowly after the 9 second hold, the TC Isolation Valve Test has failed.
