1997 Ford F150 V8 Four Wheel Drive Automatic 158000 miles
The brake light on the dash stays on. The emergency brake is not engaged, and I've checked the pedal to make sure it wasn't slightly depressed. It did go out for a short period of time while driving, but came back on after applying the brakes to stop. What could be the cause of this?
Indicates a possibkle loss of pressure in system. Check wheels for brake fluid leak and the master cyl.
If no leaks found then piston seals in M/cyl are losssing seal allowing pressure loss. Low fliud level may be causing light to come on.
