My son has a 2004 Toyota Tundra with 40,000 miles on it. A Toyota dealer in Los Angeles convinced him that he needed to have new front brake pads and the rotors turned (which might be true). The dealer also sold him a "BRAKE SYSTEM FLUSH" for an additional $150.00. The Toyota factory recommended maintenance schedule says nothing about such a service.
I've heard of bleeding the brakes on older cars if they get air in the lines, but a "brake system flush" seems to be nothing more than BLEEDING THE CUSTOMER! Would anyone care to comment on what possible justification there is for this other than dealer service sales revenue enhancement?
