The vast majority of cars equipped with disc front brakes, the friction linings which eventually wear out. As the brake pads on the front wheels wear out much faster than the rear (three times, probably), then they have to change much more frequently.
All vehicles on the master cylinder mounted transparent tanks for the brake fluid. When the liquid level in your tank drops to less than half, you should check the brake pads. The fact that the brake pads wear, the piston in the cylinder working more and more are removed from their cylinders, and the space for them, naturally, is filled with brake fluid.
Some manufacturers put on the front and rear brake pads, special devices that prevent the wear of brake pads. They are mechanical and electronic. In the first version of the worn front or rear brake pad begins to squeak unpleasantly. In the second option - if worn front and / or rear brake pad on the instrument panel lights up a separate indicator.
Replacing the brake pads do not require any special tools. The first step is pick up the car jack and remove the wheel. Use a large screwdriver to spread the pads to the starting position. Then, unscrew the bolt from the brake caliper bracket to the guide sleeve, after loosening should be able to drop the body with the brake caliper bracket to the side. Next, remove the old brake pads and study them. Also note that if you wear pads is uneven, it means that at the moment is
sprinter brake calipers complete with the brake caliper on the guide sleeves. After that, install new pads with tin damper pads.
Place and tighten the wheel in place. After that, doing a job with the same storage the other side of the car.
Once the brake pads will be replaced on both sides, is pressed several times on the brake pedal in order to choose the resulting gap between the pads, brake disc and brake caliper piston.
For cars that are installed on the rear wheels as well as front disc brakes, brake pads replacement procedure is similar to the procedure of replacing the front brake pads.Note only one fact that the brake piston is usually not pressed, and is screwed into the caliper clockwise. To do this, on its surface, you will find special poses a turnkey basis.
And something else to replace the brake linings. When you dent the piston brake cylinders in their to insert new pads, fluid from the cylinder begins to move through a special valve in the brake master cylinder in a transparent tank for brake fluid. But with this fluid will be displaced from the cylinders and the dirt that has accumulated there over the years. This mud, passing through the brake master cylinder, it can clog the valves.As a result, you will "fall through" the brake pedal: you press down on her, she stands on the site (by car, of course, slows down), and then they quietly "gone" to the Polycom.Fully brakes do not disappear, but the phenomenon is unpleasant. In this case, you can pump the brakes and, most likely, it will help, but if you have time, it is necessary to disassemble the whole brake system, all washed and clean, Blasting by compressed air, lubricated with brake fluid and reassemble. That would be safe.
