The Brake Pedal May Become Soft and/or Lowon Acura TSX

Some vehicles may develop a soft, low brake pedal. Our technicians tell us this condition may be caused by a faulty vehicle stability assist (VSA) modular control unit. If this is the case replacement of the VSA modular control unit would be required.

Pedal goes all the way to the floor and is 'mush'...but I can 'pump it up'. No weird noises or cryptic messages on the dash...no leaky fluid. Fluid reservoir remains full, and I've got good discs...just not working as it should. Still looking for a solution.

This was already fixed on my 2007 tsx a few years ago and I am taking it in again this Thursday for the same problem! The odometer only just turned over 21,000! GRRRRRRRRRRRRR!
