Example complaints

“My brakes started feeling spongy but hard to push when I would try to come to a stop. It felt at times like my car wasn't going to stop. I stopped driving it and the brake booster was replaced. At that time, I lost brakes completely. The brake peddle goes all the way to the floor when pressed. Hopefully the booster is a bad one.”

“2009 Mazda CX-9 - on 5/19/2013 the brakes were fine. The morning of the 20th my wife returned home from work, and said she heard a hissing noise from the brakes. I drove the car to work later that day and noticed the hissing sound. I also noticed that the brake pedal felt normal at first then began to get hard and the car could barley stop.”

“While driving in stop and go traffic/parking lots, etc., I had three separate incidences in which when I depressed the brake pedal I felt no resistance and there was no deceleration. The brake either finally applied itself after I got the pedal almost to the floor or I let off the brake and reapplied the pedal and it functioned normally the second time. It did not result in any accidents but left me unsure about the safety of the vehicle.”
