Winter noises
 

Hi! My car is pretty new (30 000 km P5) and I live in Toronto, where its friggin cold right now. Humans were not made to live at -15 degrees celcius with -570 degress celcius windchills, that's just not normal. In fact I think my car wasn't made for this weather eirther.

Anyways, I get these constant squeaking sounds both when break (I imagine it's break rust) and when the car is in motion, at least for the first couple of kms. Does anyone else have squeaking motion and break sounds. Can someone explain them to me.

Otherwise the car is great, I just wish it would heat up faster so that I could switch into second gear, our oil sure travels slow.

Thanks in advance for the help guys.

Hey, I too live in Toronto and have been experiencing in the cold weather the same squaking noise from the brakes. I returned to the dealership for warranty service to look into this matter. The inspected the brakes and said it was not covered warranty but they helped me clean the rotors.

My P5 has 20000km on it now, and the tech said everything is fine, rotors are fine and still alot of pad left. The squeaking noise is caused by a combination of the moisture and maybe salt depositing on the rotors, and the brake pads, made of a high composition of metal freezing up, and as you brake, it makes a metal to metal squeaking sound. I have snow tires on steelies which makes it even harder to get the rotors clean.

I would say nothing to worry about.

And do I friggin hate the stuff they put on the roads here, salt and gravel. YucK!

Do what everybody else does! Take the car out and apply even and steady pressure to the brakes to shine and remove rust formation. ALL ROTORS RUST! THey rust real fast right after you stop the car. Like only hours after, the rust can be noticed. As long as the noise disappears after a couple stops from lets say 50-60kms, then its all good!

Yup, you guys are right the brake squeaking goes away after a couple of stops. But my concern was more with another sound that sound like seagulls (happens when going around 25kms/hr, and is pretty constant) and which also seems to go away after I hit the highway. Do you guys know if it could also be from brake rust, or could it be a belt of some sort. Are there any belts that go around 30 000 kms.

thanks

I drive up to Tremblant from Ottawa a lot. The roads are crazy rutted and often have drifting and/or deep snow mixed with tons of salt. If you know Quebec "highway" 323, you know what I mean.

Needless to say, I've had lots of brake work done on my P5. It seems like every oil change, the dealer says that my rear brake slider pins are rusted, and that the rear wheels don't rotate freely (32k, 37k, 48k). Of courses this work isn't covered by the warranty.

If your slider pins are stuck, the brake pads will rub on the rotor at all times, causing premature/uneven brake pad wear. Your brakes will basically sound like seagulls, the frequency increasing as your speed increases. If you brake, the noise will go away for a few km, but come back.

I think that this should be covered by the dealer/mazda because obviously this brake design doesn't work well in areas with a lot of salt. Apparently this has been fixed with much beefier brakes on the Mazda3 (from the 6?).

-15......

I hope my P5 is a little less rattly when we get back up to that temperature. Wait until you hit -34, then you will hear interesting noises from your car!!

Good advice on the slider pins though for you eastern types with the amount of moisture you get.

It's a dry cold. HA!
