Well, today I'm pulling out my drive way to go pass by John's house(LS1fever) to go pick up a valve cover for my car and while im in reverse I slow down by pushing in the brake pedal(duh)...and next thing i know, i get tossed around in my car cause my brakes locked up...its almost as if i pulled the e-brake up hard/fast as hell...So I trying moving back forward and nothing...car wont move...almost as if i have the e-brake on...i give it a few mins...and wam, i can move forward and reverse again, but as soon as i tap the brake pedal....yup, you guessed it...freaking brakes lock up like if I were about to engage a head on collision or something...Any ideas as to what this might be guys???

also, everytime i push in the clutch pedal it makes this weird, not that quiet "woosh" sound....
