The most overlooked component is actually the brake disc
First, how often to replace the brake disc?
Brake disc replacement cycle:
In general, the brake pads need to be replaced every 30-40,000 kilometers, and the brake discs need to be replaced when they are driven to 70,000 kilometers. The use time of the brake pads is relatively short, and after the brake pads are replaced twice, it is necessary to replace the brake discs, and then travel to 8-100,000 kilometers, the rear brakes also need to be replaced. In fact, how long the vehicle's brake disc can be used mainly depends on the road conditions of the owner, the frequency of the car and the habit of using the car. Therefore, the replacement of the brake disc does not have an accurate date, and the owners need to check the wear situation regularly to ensure the safety of driving.
Second, how to determine the brake disc needs to be replaced?
1, check the thickness of the brake disc:
Most brake disc products have wear indicators, and there are 3 small pits distributed on the disc surface, and the depth of each pit is 1.5mm. When the total wear depth of both sides of the brake disc reaches 3mm, it is necessary to replace the brake disc in time.
2. Listen to the sound:
If at the same time, the car issued a "iron rub iron" silk sound or noise (brake pads just installed, will also make this sound because of running-in), at this time the brake pads must be replaced immediately. In this case, the limit mark on both sides of the brake pad has directly rubbed the brake disc, and the braking capacity of the brake pad has plummeted, which has exceeded the limit.
Three, how to deal with the brake disc rust?
1. Treatment of slight rust:
Usually, the brake disc is more common is the rust problem, if it is only slight rust, you can remove rust by continuous braking method when driving. Because the disc brake relies on the friction between the brake caliper and the brake pads to brake, the rust can be worn away by multiple braking, of course, to continue braking under the safe section.
2, serious rust treatment:
The above method is still useful for mild rust, but serious rust can not be solved. Because the rust is too stubborn, when braking, the brake pedal, the steering wheel, etc., have obvious shaking, not only can not be "polished", but also can accelerate the wear of the brake pads. Therefore, in this case, professional maintenance personnel should be found to remove the brake disc for grinding and clean the rust. If the rust is particularly serious, even a professional maintenance factory can do nothing but change a brake disc.
