ABS Brake Light on 1995 Ford F-150

My truck was not driven for about three weeks. Now the ABS light and the brake light come on and stay on when I start the truck. I can drive it so the brakes are not locked up.

ABS light and brake light illumination may be as simple as low brake fluid level in the reservoir which may be normal brake pad/brake shoe wear or a sign of a brake fluid leak which should be investigated. Check the fluid level first and top up if required. See if the lights go off. If not the problem may be a speed sensor or other ABS component. If the system uses one rear wheel speed sensor located in the differential it used to be a common Ford failure. Even if the ABS fails electrically the system has a fail safe where it reverts back to standard braking but is worth checking out as a matter of safety.

when I start it up they come on and stay on. then the next time when I start it up it might stay off for a while, but it always comes back on. parking brake cable is not stuck.
The power brake booster went bad and caused the ABS light to flash. The truck (automatic) also will not shift out of park. Does a bad brake booster cause the vehicle not to shift from park?
