I a 2002 Silverado when I step on the brakes they sometimes freeze up so Icant press down to stop
Maybe a problem with your anti-lock system. Do you have any dash lights on?
yes ABS light is on would that make my brake pedal get real hard where I cant push down on my brake pedal /
The ABS light is on to warn of a problem. Have the ABS codes read to know what is going on.
