Car began to shake violently upon highway acceleration at 45 mph and got worse at 55 mph. I immediately proceeded to the mechanic who was only several miles away. Mechanic said that car could not be pushed in neutral to get it on the lift because brake calipers were seized. Upon further inspection by mechanic it was determined that corroded brake line had burst. Mechanic said he has seen this before and that it was most likely due to salt used to treat roads during the wintertime. Calipers, rotors, pads, and brake lines all needed to be replaced. Very strange because I just had new calipers put on the car two years ago.
