Just got home from grabbing a couple drinks at the store - as I was parking my brakes went absolutely solid (the pedal wouldn't go down even while I pushed / tried to pump) and it felt like the ABS was on. I was doing this while backing up and ended up backing up straight into a Cavalier with my Silverado!!!
Anyone have any idea what sort of problem I'm looking at - this happened once in a while usually when the engine is cold but never THAT bad. Any ideas anyone?
