Replying to: wduke (May 24, 2008 3:54 pm) it has something to do with they way the metallics in the pads react to metal rotors.   read this: http://www.trustmymechanic.com/htmlmessage9.html   Replies to this message: destry (May 25, 2008 2:39 am)

Replying to: white_miata06 (May 25, 2008 12:07 am) They fixed mine since I had under 12k miles on it...If anyone else is experiencing RUST on your rotors, take it back to your dealership's service department so they can fix it.
#455 of 529 Squealing Brakes by destry May 25, 2008 (2:44 am)
I just had my disc brakes replaced and they are now squealing. My auto mechanic says this is normal, why did I have to pay for "normal brake squeal?" Is he just blowing me off? Great Site, Glenda T. FANTASTIC AUTO INSURANCE Are You OVERPAYING? Zip Code:   This unfortunately can happen more than you or I want it to. A certain amount of high-pitched brake noise is considered "normal" these days because of the harder semi-metallic brake pads that are used on cars now. In my experience, the smaller cars like Honda and Toyota seem to have the most trouble with this. Squeals heard the first few stops in the morning when the brakes are cold and somewhat damp from dew, and squeals that are heard the last few feet while coming to a stop are usually nothing to worry about.   Semi-metallic brakes are made of bits of metal shavings in place of the asbestos material that has been banned by the U.S. government. These semi-metallic brakes have great stopping power and have a long wear life, but can cause a high-pitched squeal that drives car owners crazy and frustrates mechanics who can't get it to go away to please their customers.   When are squeals not a problem? Some brands of semi-metallic pads are inherently noisier than others because of the ingredients used in the manufacture of the friction material. Think of it this way, the longer life pads or pads that claim to have more stopping power usually contain more metallic material. Yes, they will last longer and could enhance braking but the chance of causing a squeal noise is very high. The squealing noise that might be caused from use of these pads does not affect braking performance and does not indicate a brake problem.   Brake squeal is caused by vibration between the brake pads, rotors, and calipers. Having the brake rotors refinished or trued (machining a small layer of the metal away from the brake rotor to make it smooth and "true" again) and a thin layer of a silicone compound placed on the back of the brake pads are a great way to reduce the squeal if the semi-metallic pads are the culprit of the noise and not due to a worn out brake pad.   Why does this squeal happen anyway? The brake rotor is the round metal object that the brake pads squeeze together like the white part of an Oreo cookie. The rotor is metal and has a smooth slick finish, and the brake pads are made of metal shavings and also have a smooth somewhat slick finish. The more metallic material found in the pad the greater the chance for noise, and vise-versa.   The other type of brake pad is called organic. There is no metallic material used in this kind of brake pad. Organic style brake pads can only be used on vehicles that are specifically designed to use them. Improper use of organic pads on a vehicle designed to use semi-metallic can severely reduce stopping ability. Organic pads are softer than semi metallic and usually do not have a squeal problem. Unfortunately due to shorter life expectancy, inability to stop larger vehicles, and the addition of substances like asbestos in their construction, they are not very widely used.   When are squeals signaling a problem? Sometimes brake squeals are an indication that maintenance is required. Some common conditions that cause brake noise are:       *         Heat cracked or worn "un-true" rotors     *         Rough finish on resurfaced rotors     *         Loose fitting brake pads in the caliper     *         Lack of silicone compound on back of brake pad     *         Missing springs or anti-rattle clips that should be on the caliper or pad     *         Improper tightening sequence of lug nuts or caliper hardware   Most GM cars are equipped with a small thin piece of metal attached to the brake pad to act as a warning indicator when the pad material is getting low and the brake pads should be replaced. This inexpensive warning device can be deceiving though, because this warning noise is present when the brakes are not depressed. When the brakes are applied, the warning noise goes away because the indicator has now been forced against the brake rotor and is not able to vibrate which causes this whistling noise.   If you hear disc brake noises other than a squeal, it could mean your brake pads are worn out and need to be replaced. If your brake pedal feels different than normal or if you've noticed any change in the way your vehicle brakes (pulls to one side when braking or requires more pressure on the brake pedal), have the brake system inspected at once.   What should I do? What can you do as a customer to reduce the chance of squealing brakes? First of all, noisy brakes should always be inspected to make sure there isn't a problem with the braking system. If the pads have worn down to the point where metal-to-metal contact is occurring, your vehicle may not be able to stop safely, and you may damage the brake rotors or drums to the point where they have to be replaced. Sometimes a few harder-than-normal stops can "de-glaze" the brake pads and help reduce the squealing noise for a while.   There are many aftermarket brake pads that claim to be "quiet" or have been "designed" for import and front wheel drive vehicles that you can choose from. Personally, I have had the best luck replacing the brake pads on small vehicles like Honda and Toyota with original equipment pads from the dealership rather than using aftermarket brands. It is usually more expensive to purchase these pads from the dealership, but the quality is much better. I am an independent shop owner and my whole business philosophy is to buy as little as possible from dealerships, but after trying many squealing aftermarket brake pads, I have learned my lesson and pay the extra money.

Replying to: white_miata06 (May 24, 2008 11:12 am) The car is driven everyday. Still have the squeal problem when backing out of the garage. This should not be normal on any vehicle. I have a 2008 Honda Accord sitting next to the 2008 Miata and it does not squeal, even when it hasn't been driven for a couple of days.

Replying to: wduke (May 01, 2008 3:46 pm) I am looking for miata the first dealer I phoned in ny didn't want to sell it to me, sounds like getting further away from the border might work? Have they respected the warranty now you've had it for a few months or are you still just as happy. Thanks Replies to this message: wduke (Jul 17, 2008 10:24 pm) metalsmith (Jul 20, 2008 5:04 am)

Replying to: metalsmith (Jul 17, 2008 3:11 pm) Still Happy, and the dealer that I bought from has given me a call to see how everything is. They are in Southern California, and the saleman said that if I knew of anyone that was looking they would be happy to put a deal together. Seems that the first deal to a Canadian when smooth for them as well and they would do it again. Warranty has not been an issue, haven't had to use it yet. I know that the local dealer will honor it as I've talked with others that I know in the industry and they realize the scope of the imports, as a matter of fact I know of a local ford dealer who is bringing in US cars as well. If you are looking for a Mazda let me know and I will put you in touch. Will need your email so that we can exchange info..let me know. Replies to this message: metalsmith (Jul 20, 2008 5:04 am)

Replying to: wduke (Jul 17, 2008 10:24 pm) Thanks for the encouragement, I found a used car with 750 miles. I am going to go look at it, hoping to buy it and bring it back through customs, doing a road trip up through the eastern sea states and east coast of Canada. It reads that it is possible 30 day temporary permit , and my insurance company doesn't have a problem. The only caution I have seen that the fax gets to US customs, and be prepared to pay the tax and duties. Did you bring your car in yourself? Thanks
#462 of 529 Used car 750 miles by wduke Jul 20, 2008 (2:30 pm)
If the price is right it should be a no brainer if this is what you are looking for. You can have the documentation faxed to the border prior to you arriving 72 hrs before arriving (weekends don't count) Monday to Fri only and I believe between 8am and 3pm is what most of the border crossing allowing for imports. Once you clear US customs then the Canadian side will take your GST and Import Tax (6.1%) on a credit card. Yes I brought the car into Canada myself, it's a piece of cake, just make sure to fax the following to US Customs...Bill of Sale, Original Title (MSO) Manufactors Statement of Origin, and letter of No Recall, from dealer or manufactor. Good luck and hope it all goes well, zoom zoom
