I have parking brake light on on vehicle.Also the brake pedal is soft and depressess all the way to floor.I believe brake master cylinder may be leaking internally (Brake fluid seems to be ok between min and max levels) and maybe brakes pads worn out as was making noise.Please advise what problem could be and if I schedule with you to come to my home to serviec, can you do in mississauaga and approx costs and hwo I can pay(Cash,debit etc)
