What is the general clearance of the brake?
2 Answers
The brake clearance generally does not exceed 20 tracks up and down. The following is a related introduction about the brake: 1. Working principle: The brake is to give the car a resistance when parking. The handbrake of the car or the parking gear in the automatic transmission is the brake of the car. The braking system used by the car is the electronic parking brake system. The electronic parking brake system refers to the combination of temporary braking during driving and long-term braking after parking, which is realized by electronic control. The working principle of parking braking and the mechanical handbrake both achieve the effect of parking braking through the friction between the brake pads and the brake disc. 2. Types of brakes: Generally, car brakes can be divided into drum brakes and disc brakes. Small cars generally use drum brakes, that is, drum brakes.
Over the years working with cars, I've found that brake clearance is typically maintained between 0.1 to 0.3 millimeters, a range derived from standard designs of most vehicles. With prolonged use, the clearance increases as brake pads wear down. If the clearance is too small, brakes may seize or overheat; if too large, the pedal feels spongy with delayed response, compromising safety. Modern cars feature automatic adjustment mechanisms, but older models might require manual calibration. I recommend having a professional inspection every 10,000 kilometers or annually to ensure everything's in order. This clearance is crucial for braking performance—poor maintenance can increase stopping distance, which is dangerous in emergencies. Pay attention to unusual noises or changes in pedal feel during braking; these may indicate clearance issues requiring immediate attention. Never attempt DIY adjustments—always consult professionals for repairs, as vehicle safety is paramount.
