Q. The front brakes and pads of my 2010 Toyota RAV4 were replaced 5,000 miles ago and the rears about 10,000 miles ago. Lately I’ve noticed that while braking, the brakes pulsate (I’d guess about once per wheel rotation) which is very annoying and that the problem seems to be getting worse. The Toyota dealer verified the uneven braking and noted that the pads are not worn but recommends replacing brakes and rotors on all four wheels at a cost of about $1,100. My local garage says that the problem is with one of the rotors but can’t determine which one, so nothing should be done at this time. So, what do I do: live with the problem or pay an exorbitant amount for an unnecessary brake job?
