    My 90 k5 brake indicator on the dash is flashing 5 short one long. Anyoe know off hand what that means. My brakes pull hard right when I stop. The front are disc, rear drum.

    You have ABS, specifically rear wheel ABS. Mine gives me an 81 every now and again, something about the cylinders up by the master aren't responding to the brake ECU properly.

    I disconnected the brake ECU.
