The braking system of your vehicle is one of the most delicate and complex of all parts. It is made up of a lot of components and parts that even a single failure could lead to the collapse of the whole braking system. Since you’re going to be using the brakes every single time you drive, you need to ensure that the braking system is in good condition. Keeping the brake parts healthy will be a good sign for your car, as you will feel confident knowing that everything is well with your car. There have been many instances where people feel nervous because their brakes don’t work too well.
If you take good care of the brake parts, then you will definitely feel more confident driving the car. This confidence might be involuntary, but you will still definitely feel better knowing that you’re driving a very safe car which won’t disappoint you while braking. Since there are so many parts in the braking system, it is a good idea to have all of them checked at a mechanic so that you will know for sure that everything is alright. This way, you can keep the entire braking system in a good condition.
Some brake pads have shims built into them in order to deliberately make a grinding noise when they wear out, or sometimes a squeaking noise.
This is then designed to alert the driver to the problem so that they get their brake pads replaced. If the brake pads continue to grind then the calipers might connect directly with the brake rotors and this can cause them to cut out a groove in the rotor meaning that the rotor needs to be either replaced or turned around. You might also need to readjust the calipers or add a lubricant.
While there are other brake parts it is the brake pads and brake rotors that control most of their function. Ensure at all times that your brake pads and brake rotors are in good condition. If you think that your brake pads are wearing down, or that your brake rotors might be warped then you should look into getting those brake parts repaired. Look out for your brakes becoming less responsive, for them becoming uneven, or for vibrations being felt in the wheel.
Brake pads are originally made from organic materials such as carbon and asbestos which was held in place by a resin. The use of asbestos however was banned in most territories though some non-metallic brake pads are still sold (though only vehicles that are designed for them can use them). Recently Kevlar (the material used in bullet proof vests) is more commonly used and most brake pads today are semi metallic though the exact formulas are often secret. They will often however use copper, steel wool shavings, brass and more and are again held together by a resin.
As brake pads are mostly metallic they can now last over thousands of miles though they are noisier than their organic predecessors. This noise is caused by the shavings rubbing against the steel rotors every time they go around. Some brake shoes however are marketed as being quieter than others.
Brake pads are located along the top of the front wheel, and this means that you can see them work. However here it is not the calipers themselves which squeeze the top of the wheel, but rather the two rubber pieces. These can also be called rubber shoes and this is why sometimes brake pads can be known as brake shoes. This is the exact same as brake shoes in a car, but is slightly different in that the brake pads in a car will grip the brake rotors rather than the tire itself (as in the case of a bike).
The pressure between the brake shoes and the brake rotors is what eventually slows down and stops the wheels in a disc brake system. Eventually over time however the brake pads will wear down and this compromises the safety of the driver – this then being when the driver needs to get replacement auto parts.
Brake pads are equally crucial auto parts that are necessary for the brake's function. Brake pads are the auto parts that take the brunt of the force necessary to stop the car. In a disc brake system the pedal will activate a hydraulic line which will squeeze calipers against the brake rotors. Brake pads are positioned between the calipers and the rotors so that the calipers are not gripping directly onto the brake rotors. These are also important to be able to absorb that amount of energy and heat and thus stop the car.
If you have a multi-gear bicycle then this can help you to understand how brake pads work. Here the grip on the handles is the equivalent of the brake pedals and when you squeeze the grip, the two calipers are squeezed together over the bike tire.
Brake rotors can become damaged in several ways. One problem is excess rust which is common for iron brake rotors. It is normal for small amounts rust to be found on brake rotors, but as this grows it becomes more of a problem and means that the brake rotors should be replaced. To try and avoid this from occurring you can avoid leaving your vehicle outdoors where it will be more vulnerable to the weather. A temporary solution meanwhile is to try removing rust from the brake rotors by wiping them down.
Another common problem is warping and this occurs as mentioned as a result of heat. Here excessive heat that comes from friction can cause the expansion of the braking surface of the brake rotors and generally results in the brake rotors becoming malformed. You might notice that your brake rotors have become warped if you notice vibration in the steering wheel or elsewhere when braking.
To repair this you can replace the brake rotors by finding a store to buy new auto parts.
Alternatively the brake rotors can be removed from the car and then put through a machining tool which will once again level the brake rotors' surfaces. Another way in which brake rotors can become damaged is if the brake pads are damaged, or if something should get trapped between them. Driving fast over gravel for instance can cause gravel to get kicked up and caught between the brake pads and the brake rotors. This then means that when you brake it will press stones against the rotors and cause damage or extra wearing. If you have a stone caught between your brake pads and your brake rotors then you make hear a crunching or squeaking noise when you drive (even without braking) and will likely find that they are not as effective as they should be. If the brake pads have become worn, you may again notice a slight squeaking noise when braking.
Other less common problems can be cracking on the blade rotors that have cross drilling or scoring.
