Replacing the brake discs with ventilated by VAZ 2109, due to some reasons.
In conditions of intensive movement, with frequent braking and high speed, the “failure” of the brakes may occur. This is due to heating brakes, due to friction of the pads on the brake disk. During overheating of the brakes, boiling of the brake fluid begins, because the temperature of the brake system nodes can reach 600 ° C. At this temperature, the red color of the brake discs will be visible in the dark. But do not forget that brake fluid can also affect the effectiveness of brakes, which has not changed for a long time and managed to nourish moisture.
And yet there is a way to fight the heating brakes. This is the replacement of the brake discs with ventilated. Experts say that ventilated discs are cooled much better than non -premised.
Ventilated discs have a large thickness, so to replace the brake discs, you will also have to replace the brake caliper. Replacing the brake cylinder and brake pads will not be required. And those details that we will change are suitable from VAZ 2112.
