I have a 2005 4 runner who needs brakes at 29,600 miles. The toyota dealer that normally services my truck sent me a coupon for a front brake service for $89.95. However when i called to verify the coupon they told me that was without resurfacing the discs or rotors. that it would cost 189.99. Also that if i wouldn't get the discs resurfaced that the new brakes would not be covered if the brakes started to squeal. Is it possible at 29,600 i have to resurface the discs or is that a sales pitch to get more money.
