I purchased a new 2003 4 runner from toms river Toyota. All service of the vehicle performed there. Over a year ago we complained low a low brake pedal. Dealer said nothing was defective. Recently dealer recommended rear brake service. Problem still not resolved. On last service visit the dealer advised me that Toyota issued a service bulletin requiring a pad spacer being installed. But now due the mileage being over the 50000 mile warranty, dealer requires >$ 250. Be paid by owner to repair this issue. No such service bulletins were found on this website search.
When braking at any speed the brake pedal goes to the floor, causing extended stopping distance. Dealership was notified, but did not resolve the problem.
