RX330:brakelights in dash doesn't go off

i have a toyota harrier 2003, just like lexus RX330. I recently replaced the JOINT ASSES at the front. Since i replaced those,the ABS and handbrake light in the dashboard are on when you drive..Normally it must go off, when the car has start, but it stays on..Or often it goes off, but while you drive it goes on...So my question is: What must i do to repair this problem?????
