I read about your investigation into the 2010 prius braking difficulties when going over potholes or uneven road surfaces. I have a 2003 Camry and have been having the same exact problem for years. I actually took the car into the dealership and they replaced the sensors on the abs, but this did not fix the problem and they said there was nothing else they could do. Anyway I just thought you would like to know that this problem is not limited to the prius in 2010.
I have experienced braking problems similar to those prompting the prius recall since approximately October, 2009. If the brake is engaged on rough pavement (bumpy, potholes,etc), it shudders and does not engage for several seconds even when the pedal is depressed completely to the floor. I have had the rotors and pads replaced within the last six months and have had the abs sensors cleaned and lines inspected with no improvement. The problem occurs on both wet and dry pavement.
