The brake system is one of those that is used more often than others, and therefore even at the design stage they pay close attention to it. Manufacturers are doing everything possible so that it serves as long as possible. But still, sometime there comes a time when the brake pads require replacement. The wear rate depends on many factors: the type of gearbox, operating conditions, manufacturer, driving style, etc. The main thing is to remember that you can not delay in replacing brake pads in any case. Not only your own life, but also the life of others depends on it.
When to change?
Before you ask yourself how to replace the front brake pads or the rear ones, you should accurately determine that this moment has arrived. How to do it? Yes, very simple. As a rule, they are equipped with a special wear sensor, which starts to emit a nasty metal screech during braking, which is almost impossible not to hear. In any case, a periodic visual inspection of the brake pads is necessary. If their thickness has become less than 3 mm, but there is no screech, you can safely proceed to the replacement.
Which to choose?
Before replacing brake pads, you need to decide on their choice. It is advisable to buy original parts, choosing them according to special catalogs, depending on the make of the car, year of manufacture, body type, etc., or purchase goods from well-known manufacturers. Otherwise, you can easily run into a fake.
How to replace brake pads
First, with the help of a jack, it is necessary to raise the car (having previously installed thrust blocks) and remove the wheels. It is better to remove two wheels at once, since when working with one, you can always refer to the other as a reference. After this, you need to unscrew the caliper mounting bolt. Before replacing brake pads, it is necessary to carefully check the condition of the anthers of the guides and the cylinder. In case of defects, they must also be replaced.
At the next stage, you should get the guides out of the disc bracket, carefully clean them with fine emery cloth and grease with lithol. After that, you need to return the guides to the place, after putting on the anthers.
Now you need to get the old pads. Before replacing brake pads, the grooves where they are located should be thoroughly cleaned of dirt. When installing new pads, it is necessary to put a special graphite-containing lubricant under them. After that, you need to return to the same place tin damper gaskets. Now you need to reinstall the brake caliper and tighten all the bolts. That's all. It remains to put the wheel and perform the same operations with another. At the end of the work, use the jack to lower the car.
At the end, it is absolutely necessary to pump the brakes to get rid of the gaps that form between the pads and the disc, as well as the piston of the brake caliper. To do this, just press several times and immediately release the brake pedal.
Usually, even an inexperienced motorist takes about one hour to complete the work. Speaking about how to replace the rear brake pads, it is worth noting that all the work is best done on the flyover. In addition, it is necessary to loosen the tension of the hand brake cable .
