1986 Ford F-150 w/175,000 miles. The brakes have recently started making a noise like air escaping. Any time you depress the brake pedal, a hissing moise is heard. It continues for as long as your foot is depressing the pedal (until you depress the pedal as far as it will go). The master cylinder level is good and there are no obvious fluid leaks anywhere.
