My braking power assist fails occasionally when I am making a hard turn (as when parking), either right or left , but recovers when I straighten out my steering wheel. This began after I replaced my front wheel rotors and brake pads at around120,000 miles. My power assist unit failed completely around 138. 000 miles, so I had it and my master brake unit replaced. I continue to experience the same braking problem as before.
