1997 Honda Accord (front) wheels wobbles when I apply the b

I had a problem with coolant hose at around the start of the year (see my previous post) and the car was parked in the cold (two snow storms) for about two month (only got driven twice during that time for very short period of time)
Ater I replaced the hose and started to drive it again there is this new problem, the wheels shake badly when I apply the brake, the higher the speed the
worse they shake

I went to pepboy and the mechanic say the brakes are in good condition, any guess what caused the wheels to shake?
