For life, of course, we should enjoy ourselves, but why are we always troubled by waiting for the bus or crowded subway? It's not because we don't have a stress-sharing car in our lives! I think you all know the speed of the car and that's not to be taken lightly, but we also know a little bit about cars. Today xiaobian for you to introduce the brake wear indicator light this problem.
Brake pad wear indicator light: how brake pad alarm light works
The brake pad alarm system is to insert the alarm line into the brake pad. If the brake pad wears away too much, the sensor line will be friction, and the sensor line will be worn out or coupled with the brake disc, which will lead to the change of resistance, thus generating the change of current and finally giving the alarm.
In the passive alarm, the brake system we use relies on the force of vacuum pump. The brake oil pushes the brake pump and ACTS on the brake pad to clamp the brake disc for the purpose of braking. If the brake pads are worn to their limit, the brake oil level will drop significantly below the minimum scale, triggering an alarm.
Other causes of brake pad failure lights caused by brake oil:
Oil leakage from the brake pump and oil pipe: Oil leakage from the brake pump and oil pipe will cause the brake fluid level in the brake oil pot to be too low, and the brake oil will sound an alarm.
Oil spills while climbing: Driving on flat ground is fine, but when climbing and braking hard, the slope is too steep to allow the oil to spill out and the level indicator will issue a false alarm, which only needs to be refill with the brake oil.
Brake wear indicator: The car does not have brake sensors. What should I do?
The thickness of a new brake pad is generally around 1.5cm, which gets thinner and thinner with continuous use. If the thickness of the brake pad friction block is less than 3mm, it needs to be replaced in time. Generally speaking, it needs to be replaced once every 30,000 to 40,000 kilometers (depending on personal use). And the new replacement brake pads also need a run-in period, after which to play its maximum effectiveness.
Each brake pad has a raised mark on both sides and is about 2-3mm thick, which is also the limit for replacement. When worn to the limit position, the alarm plate will come into contact with the brake disc, causing noise. No brake alarm lights can be judged by the sound of the brake pads. If you tap the brakes and the brakes make a sustained "hiss" sound, you should pay attention to the brake pads and replace them in time.
Brake wear indicator: How long will the brake wear alarm light last?
Theoretically speaking, whether the brake pad by induction wire or iron plate alarm, generally can run 1000 kilometers or more, but considering that different owners of different driving habits, so the speed of wear and tear after the brake can not be determined, there is no conclusion on how many kilometers after the brake alarm can run. But for the sake of safety, I suggest that you should take the time to go to the 4S shop or repair shop for replacement after the brake pad alarm.
