2009 Mazda5 Brake pedal goes to floor - Intermittent
First time it happened was when I was picking up the car from the Mazda dealer in the evening after they had closed over a year ago. No brake work was done during this service visit. Got in the car and started driving, brake pedal went all the way to the floor numerous times and consistently. Young kid who drove me to the remote lot to get the car also drove it and said it seemed like it didn't have any brake fluid. Left the car at the dealer, they looked at it the following day. The problem resolved itself and they could find nothing wrong. A few months later, it happened again while doing local driving, but only really went to the floor once; then somewhat inconsistent braking and then seemed to resolve. Same thing a few months later.
This past summer it started occurring on a more frequent basis. While doing local driving I would brake and the pedal would travel all the way to the floor. It might repeat a second time or not and then was generally a little inconsistent (in a way that probably only I could tell since I drive the car on a regular basis). I realized when this was happening that there was a whining or wheezing sound when I took my foot off the brake that would start after the occurrence of the first "pedal to the floor". At a red light sitting longer it would be a longer wheezing/whining sound compared to a stop sign which would produce a tiny whine. A few minutes or hours or days later, the whine would go away and the braking would feel normal. Every time I have tried to get it to the dealer while this was happening, it resolved before I got there. Since the pedal to the floor is a one (or on rare occasions two) time event, there is no way for me to get it to the dealer while it's doing it. It seems to currently be doing it on average every 2 weeks.
It is still under warranty (extended warranty). It has been to the Mazda dealer FOUR times for this issue: new Master Cylinder, new power booster and they have kept it and supposedly driven it trying to recreate the problem many days but have not been able to. Mazda has stated they will not cover any more work for this under warranty, since they are unable to re-create the problem.
Any ideas ?? (either mechanical or where to go with the problem with Mazda) ????
