These flat quadrangular plates help in reducing the wheel rotations by clamping over the wheel disc causing friction. To put it simply, the wheel of your vehicle or the tire is attached to a spinning disc. Before you purchase new brake pad consult the car manual about the exact specifications for your car type.Once the braking unit is fitted, make sure that you have not tinkered with the pressure hose attached to it that carries the brake fluid. Unscrewing the nut at this point will render it loose and you can easily spot the inner brake pads. Brake pads are fitted so that they are almost in contact with wheel disc, and when the brakes are applied, two or more brake pads approximate against each other holding the disc wheel in between.

This is pretty easy, and you will need to engage the car in the largest gear first and, or apply the handbrakes full-on before unbolting.When to Change Brake Pads?There are two ways to ascertain if your brake pads need to be changed. Jacking up is quite easy but make sure that your jack is steady and properly elevated to prevent any mishaps.Now, since you might have used the handbrakes to steady the wheel while unbolting, you will need to release it, else the braking unit will not come off.Most braking units are attached at a single point to adjacent car body, and this is usually at the bottom or the lower side. This is a slow process and depends upon the number of times brakes are applied and the individual braking style.

Very simply, when you start hearing squeaking every time you brake, this is a good indication that you might have to change the brake pads. Engine revolutions cause the disc to spin resulting in wheel rotations.Once the wheel is down, the inner wheel disc is exposed along with the braking unit that can be easily seen disrupting the disc circumference.Why Change Brake Pads?Brake pads decrease wheel speed by causing friction against the wheel disc and hence, over time, get eroded gradually. The braking unit is attached to some other adjacent structure and the only point where it comes in contact with the disc is at the brake pads.Changing Brake PadsTo start with, you need new brake pads, and a simple set of tools that come along with your car tool kit. Eventually, brake pads erode away and expose the steel or metal surface beneath. The car will always stop but this will eventually cause a great damage to the braking unit as well as the wheel disc surface. With squeaking brakes, you will need to change them within a month or sooner to avoid greater damage. Put back the wheel now and you are ready to use your new brake pads..To start with, you will need to know a few basics about brake pads and what they do. Heres your key-What do Brake Pads do?Brake pads are simple, flat metal structures that are fitted inside the braking unit attached on the wheel of a vehicle.The other way is to take off the car wheel, and inspect how much of the brake pad lining is still remaining through certain holes on the braking unit. You will need to repeat the same process for all the wheels but be very sure that you have carefully checked if the brakes are working alright before you take the car out to the roads.Although it may sound a bit technical and complicated, changing brake pads on your vehicle wheels is a very easy do it yourself task that you can learn right away, and with some experience.

They are fitted with metal points that are exposed even before the brake lining is completely eroded. Thus you have some time before you have to change them. All you now need to do is take out worn out pads replace them with fresh ones. The resultant friction causes a drastic reduction in speed. This way whenever you apply the brakes, the wheel disc rubs against the brake metal plates with a shrill squeaking sound.With the jack up, the first thing to do is to knock the wheel cover off, and unbolt the wheel from the car.When you have all the necessary material on your hands, you will need to park your car safely on non woven fabric factory an even surface, like your garage, and jack up the wheels. Putting everything back is very easy should take you not more than a few minutes.
