Some 2004-07 Acura TSX models are prone to producing a pulsation from the brake pedal and/or a vibration through the steering column when the brakes are applied on the open road.
One likely cause, Acura said, is excess thickness variation in the front brake rotors. Overly aggressive brake pad material is the source of the trouble.
Machining the rotors (Acura recommends an on-car brake lathe) and installing new pads with a different friction formulation, part No. 45022-SEC-A00, should eliminate the brake trouble.
