1992 Other GMC Models V8 Four Wheel Drive Automatic 140000 miles
Within the last 2 days, both the ABS and Brake indicator lights have turned on and remained on when I am driving the vehicle. The brake pedal has also become very soft (spongy) and travels towards the floor a lot more than usual. The vehicle stops but not as quickly as before. I can't seem to find any fluid leaks (yet). Any advice on troubleshooting?
