In order to ensure safe driving, it is necessary to keep all parts of the car in good condition. Even the highest quality parts can fail over time, but the owner does not always have the opportunity to seek help from professionals. If your old brake pads were faulty and you were involved in an accident, consider – it might be worth recycling your car: https://towingandscrapcarremoval.ca/scrap-car-removal-north-york.
Some things, however, can be done independently, having previously read the instructions. For example, every driver needs to know how to change the brake pads and in what sequence this procedure is performed.
What you need to know about brake pads
Although the pads are an important part of the braking system, this part is actually a consumable that wears out quite quickly. After all, the very principle of its operation is based on the use of friction force, which occurs at the moment of contact of the brake pad with the drum or disc. As a result of frictional force, there is a heating, that is, the kinetic energy is converted into thermal energy, the car reduces speed and stops.
Because of this heating, the brake pad fails quite quickly. The material from which it is made hardens, and this part copes with its task worse, until it stops functioning at all.
Interestingly, in most cars, the front pads fail earlier than the rear pads due to higher wear and tear, meaning they require more frequent replacement.
When it’s time to replace them
Many modern vehicles have a brake pad wear sensor. In this case, the system will signal itself that it is time to replace this part.
If there is no sensor, the motorist will have to monitor it himself. You just need to remember that the pads are wearing out unevenly, this process can be influenced by many factors, so it is useless to look at the mileage. You should listen to the condition of the car. If there is a noise when braking, it is time to change the pads. The fact is that many manufacturing companies equip the pads with a kind of indicator. This is a piece of metal, which as it wears begins to come into contact with the brake disc, also metal. This results in a characteristic sound.
How to put a new brake pad with your own hands
The step by step replacement of the brake pad looks like this:
At the initial stage, you will have to remove the wheel to gain access to the caliper and brake pads. It is better to do this with a jack, if the motorist does not have an elevator. But first it is necessary to loosen the nuts that hold the wheel. And you must act carefully.
Under those wheels of the car that will not be removed yet, set the wheel chocks. Pads should be replaced one by one. Under the rigid part of the car, you need to put another support, so as not to rely solely on the jack.
After the wheel is removed, it is necessary to check the condition of the brake discs. It is recommended to check with the manual of the car to understand whether their thickness meets the standards.
Check the level of brake fluid. There should be some residual, but if it’s up to the max, you’ll need to pump it out with a syringe.
Start working on the caliper. Using a flat screwdriver, push the caliper piston in to install the new pads into it. At the same time, the compression spring, which holds the old brake pad on the outside, must be removed. The old pads have to be gotten rid of. The caliper itself will also have to be removed.
Using a metal brush, clean the places where the new pads will be installed. Then they are replaced and the caliper is also returned to its place.
After that, return the wheel back in place, all actions are performed in reverse order. If the motorist is not confident in his abilities, he can watch a video beforehand. But really, you just need to act carefully, and then everything will work out.
