Having spent the last 3 weeks reading and gathering as much info as possible on this heavy brake dust build up on rear brakes/grooving which I have on the rears rotors I decided to finally go to the dealership with the comments from this forum and get them to look at it.
......anyway I took it in and it turned out the Mazda rep was there at the time too....PERFECT!......they took my car up on the hoist...disassembled the brake assembly and to their surprise found both rear pads with very unusual degradation and pitting....very intensely worn....only 375km too!.....Immediately the rep asked for a digital camera and decided to send pictures off to quality assurance at Mazda for further analysis and also asked straight away for the guys at service to replace all 4 rotors and pads......by the way the service guys are the best in Ontario......!!
I am very happy that they have responded so quick....obviously the rep being there made a big difference but in a way when the rep said he had never seen the problem before I was a little suspicous of this...especially after reading about other owners from ontario with the same problem....at least they now have headstart on the situation and is now on its way to QA....lets hope it gets a service bulletin.....lets see if theres a difference with this new brake assembly......one thing that I noticed as did the service manager.....a lot of salt and grit around the wheel well area.....so dirt and sand could have caused this but I find this hard to accept as my last car...BMW X5 had no such problems...especially in winter with same road salt conditions!..rotors were silky smooth!!....maybe its because its a BMW!
Anyway I want to thank forums like these for making problems like this more aware to others and if it weren't...I can imagine that I would NEVER EVER pay any attention to the rotors...and who knows maybe that would have lead to problems down the road....
Other than the brake problem....I LOVE THE CAR!
