But if you start to notice it regularly, or if you notice a burnt smell during normal driving conditions, you have a bigger problem. It might be a caliper has seized, which causes the brake pad to drag against the rotor. It might also be a parking brake is still being applied, or you leave your foot lightly on the brakes, and it continues to drag. Brakes overheat when constant pressure is applied between the brake pads, calipers, and rotors. The more pressure, the greater the chance of problems developing over time.
This means as soon as you discover overheating, your best course of action is to cool your brakes down quickly. Overheated brakes can cool down simply by not using the brakes.
Try to do this for five minutes or so, to give your brakes a chance to cool. This will keep the pads and rotors from warping because of the concentrated heat. Applying this to this discussion on brakes, one could assume that if brakes heat and smoke, then they must be able to catch fire as well. Brakes can catch fire for a variety of reasons. It can be from improper car maintenance. Or from careless driving. They often brake too hard, keep their foot attached to the brake pedal, and pound on the brakes on a regular basis.
The friction it causes between the brake pads, calipers, and discs is a continual process. Eventually, that heat has nowhere else to go, and it catches fire. In some cases, the parts that make up the braking system no longer fit well together. When pressure is placed on parts in the wrong manner, that pressure can cause sparks, which leads to fire. There are a number of brake pads out there and most require a bedding-in process specific to that manufacturer. Bedding-in your brakes requires quite a bit of accelerating and quick decelerating.
The film is the brake material transferred onto the rotor. The blue tint is a sign that the rotor reached an appropriate break-in temperature. If you put on new brake pads but still have old rotors, you may need to complete a second bed-in cycle. There are a few other issues that may cause your new brakes to smell or smoke. Here are a couple of other possibilities:. New rotors are generally coated with a rust inhibitor, so if you installed new pads and rotors, this could be the problem.
The rust inhibitor burns off the first few times you use the brakes. This can cause smoke, which also might smell. The easiest way to avoid this issue is to wash your new rotors with soap and water before you install them to remove the coating. You can also just use brake cleaner to remove the coating. A stuck caliper could be the cause of your brakes smoking.
This generally only happens with older brakes but is worth looking at in the rare case it may be the cause. Let me start by explaining what a caliper does. A caliper pushes against the rotor and causes friction, which slows the wheel down. Dirt or corrosion can cause a caliper to stick. A stuck caliper will cause your brake pad to overheat severely, causing smoke. A good sign that you have a stuck caliper besides smoke is if one side of your brakes is worn far more than the other side. Finally, after driving for half a mile around 25mph there was no smell and no smoking.
Also, when the wheels do smoke, it is only immediately after braking not all the time. Once I got to work today, I saw that some of the anti-seize that I applied oozed down the side of the outer brake pads a little I might have used a little too much. The car also brakes in a straight line consistently, I have no brake pedal pulsations, and the pedal feels great. If my memory serves me correctly, those C-Max pads have a special surface on them designed to bed them in quickly.
It is very aggressive, and as a result heats up fast. I do not believe you are supposed to do any aggressive stopping with it to bed them in, just put them on, and drive normally. I think, until they have worn through that coating on the pads, that they are going to run a bit hot, and probably smell, and maybe even smoke a bit. I can occasionally smell the pads still, but no smoking. Hopefully the issue is solved.
We had very similar results with those pads on my mothers Caravan. Overall, I do like the way those pads work, nice confident stopping with them. The smell may also be part of this. In truth, you should wash new rotors with soap and water before installation to remove this coating and prevent it from contaminating the new brake pads.
