Replying to: sedmund (Nov 18, 2008 7:41 pm) This just got done on my 09 GT 6s and it has indeed addressed the problem. There are 6 different parts that needed to be replaced as part of this SB and my dealership had to order them first. But finally this annoying noise is gone and in fact now the engine "sounds" smoother when starting from idle

Hi All! I bought my Black 09 Mazda 6i Touring just over a year ago. Still in love with it! I am just shy of 21,000 miles (how did that happen so fast?!). I have a question for those of you who are more mechanically inclined. When I am driving at a low speed (in a parking lot or going up my driveway) and step on the brake to come to a complete stop, I hear a noise. It's metallic, seems to be coming from the front end and sounds like a "clank" or "clunk". Kind of like two metal plates coming into contact. It doesn't do it every time I stop, and it never does it at highway speeds or in street traffic. I've asked the service guys to check the brakes and investigate this noise a couple of times. They say everything looks fine. Last week when I was in for an oil change, I asked the service manager to check it again. Without hearing the noise, he said it was being caused by a "pad shift." Something about a gap between the brake pads and whatever they come into contact with (I can't remember exactly what part he said). He also said it's completely normal and after checking the brake system, he said everything is just fine. My boyfriend (who is enough of a mechanic to work on his own car) says he's never heard of it and he doesn't believe the service guy. Are any of you 09 Mazda 6 drivers experiencing this noise? Does anyone know what "pad shift" is? Did he just make this up? Thanks!

Replying to: weathergirl (Nov 08, 2009 6:13 pm) Interesting name! I worked for a local weather team at our ABC affiliate for a while - big weather nerd here! Regarding pad-shift, I'm actually familiar with what the dealer was talking about. I have an '06 Accord, and my dad had an '03 and an '05 (all are basically the same design). When backing up, I hear a metallic "click" or "pop" noise when applying the brake. When applying the brake once moving forward again, you hear it "click" back into place. My dealer explained to me that this is a "floating caliper" design. While I don't understand the purpose, I do understand the method of how this works. Its almost like the adjustable wrench, that you can slide one way or another to make it open wider. Once it "pops" forward or backward, it doesn't do it again until you apply the brake while moving the other direction. I've got 53k miles on my '06 and have never had an issue with the brakes, despite the consistent "pop" in situations I've described. Odd, but never problematic; I have the original pads and rotors, and have never experienced problems when panic braking (using Anti-Lock and all). Don't worry too much about this; I'm not a Mazda guy, but I don't believe that the dealer is leading you astray - they just don't know how to describe it well; I doubt I made a whole lot of sense either! Hope you continue liking your 6; my girlfriend wants one in Sangria Red!

Replying to: thegraduate (Nov 08, 2009 8:28 pm) Thank you so much for your explanation of Pad Shift! I am relieved to hear that other cars do actually do this and that your brakes continued to work normally. I will be sure to pass along your description to my also-skeptical boyfriend and do some follow up research on the topic. I'll also try not to squint suspiciously at the service manager anymore. I hope your girlfriend gets her dream car! I have no regrets with mine. Thanks again!

600 miles on it. 2 days after delivery, driving on Rt1 40 mph in 4,5,or even 6th gear, light foot on pedal as in traffic. Engine will occasionally hesitate,skip a little. not a full sputter just enough hesitation to feel it in car. Also seems to happen more when cold and sometimes when cresting or entering a hill. I think it's either defect or design flaw in drive by wire/throttle. Mazda tech admits it's there but says it's within normal specs. Anyone else w/manual notice this or have issue?. another mazda owner had pedal replaced & noticed 95% improvement. So far dealer & mazda not offering to fix or even admit it's problem. Ruins a great driving car. & I've had 2 prior mazdas both w/ manuals - lasted 10+ each & over 115K miles on them so I'm used to clutch etc.

Replying to: 626gt (Nov 12, 2009 10:15 am) Just a thought. I'd try it with and without A/C on; see if it stops when the A/C isn't running. With a GT model I'm assuming you have Automatic Climate Control, which if like Honda, runs the A/C whether or not cool air is needed. I hope this is what you're feeling! TheGrad |

I occasionally have the same problem. When it happens it occurs only once per day in the morning during the first 3 minutes of operation as I slowly accelerate. It would definetly bother me also if it happened all the time. There are so few manual transmission cars out there a tsb may be slow in coming and I hope your dealer figures it out. When you get an answer please post it.Good luck.

Replying to: 626gt (Nov 12, 2009 10:15 am) 35-50 mph. It is random and unpredictable. So far I have not been able to demonstrate it to the dealer- but they haven't really been trying very hard to find it either. I have put the car in the hands of an independent car-care professional so that I can get a verification that the problem exists. Add me to the list in case anyone figures this one out.
