Hello all Prado120 drivers. I have a Prado with a similar problem The traction conrol light is on ABS also, the buzzer runs permananently. Brake power assitant has failed so the brakes will function but only with very hard pedal pressure. Has anyone had this ? Today, Totota Service centre quoted me $4,500 to repair it. Has anyone had this and if so can you adise me of the repair cost. This vehicle has done less than 100,000km and the roughest driving is going over suburban speed humps. hardly anything rough LOL I am curious to know of the expereince of others. Regards Rodoz
