The brakes of many cars are the front disc and the rear drum. This is because of the cost, so many people think that the disc brake is more powerful, but in fact the drum brake is more powerful, and the advantage of the disc brake is excellent heat dissipation. Hot! It is the enemy of the brake system. When the brakes are exposed to high heat, they will deteriorate and harden to reduce the friction coefficient. Of course, the car will not stop. Therefore, the high-quality brake pads are modified to withstand high temperatures, and the replacement of the large disk is to slow the temperature rise, so to improve the heat resistance of the brakes, as long as high-quality and large brake pads and brakes are used The disk is just fine. But don't forget the brake fluid that transmits the pressure. Brake fluid that is too poor in quality is easily vaporized into gas when the temperature is high. It is also the main cause of brake failure. Brake pads: The original brake pads have to take into account the requirements of cost, durability, cleanliness (brake powder) and low temperature efficiency. Generally speaking, the coefficient of friction (mu) will not be very high (probably below 0.4), and most can not withstand more than 300 At a temperature of ℃, performance degradation will occur after repeated use. Therefore, the replacement of high-performance brake pads is the first step for us to modify the brake system. When choosing high-performance brake pads, be careful not to be greedy for large mu numbers and ultra-high temperatures. Too high a friction coefficient will make the braking action at slow speeds too sensitive. Every time you tap the brake pedal, the passengers in the car will roll over. In addition Brake discs also reduce life due to increased friction. High-temperature-resistant brake pads are actually not very effective at low temperatures. For example, the IDIC3 brake pads used in our fleet have an operating temperature starting from 300 ° C. Therefore, the driver will refuel at the same time while using the left Foot brake to bring the brake pads to working temperature. I suggest that general car fans can choose "sports" brake pads with an operating temperature of about 0 to 500 degrees Celsius and a mu value of more than 0.4, which can meet the needs of most situations (IDI, PFC, Ferodo and Projectmu have This type is selected). It should be reminded that if some brake pads with high initial operating temperature are selected, the owner should be particularly careful when driving in the morning, and pay more attention to it in winter. Brake Fluid: With high-temperature resistant "sports" brake pads, of course, you need to have matching brake fluid. The highest standard of brake fluid on the market today is DOT5. The dry boiling point of brake fluid that meets this standard is 260 ° C. When the temperature of the brake caliper piston is higher than this dry boiling point, it will cause part of the brake fluid to vaporize. And when there is too much air in the hydraulic system, it will make the stroke of the brake pedal become longer. In severe cases, the brake pedal may not be able to stop the brake when the pedal is pressed! In addition, the brake fluid is a very "absorbent" substance that penetrates the air The boiling point will be reduced after the moisture content (the boiling point of water can be only 100 ℃), taking the common DOT4 brake oil as an example, the dry boiling point is 230 ℃, when 1% of water is infiltrated, the boiling point will be reduced to only 118 degrees! Therefore, if you like to show the performance of your car from time to time, you should change the brake fluid frequently. Brake fluid for pure competition (dry boiling point above 330 ℃) is not only expensive (about 600 yuan / liter), but also needs to be replaced and “emptied†more often (our team must change after every practice), Unless you are ready to show your skills on the track, the brake fluid above DOT4 should meet the requirements of most fans. Brake hose: The brake hoses of most street cars are made of plastic materials (such as rubber), which are more likely to leak oil and absorb moisture at the interface, and these tubes will expand due to heat and pressure during high-strength braking, so that The brake pedal stroke becomes longer and affects the pedal feel. The brake hose (brake steel hose) made of steel wire braid is not only heat-resistant, but also the strong steel wire layer can provide good protection, which greatly reduces the possibility of the brake hose being punctured by foreign objects. Modifications worth investing in. Common tubing brands are Goodridge and Earl "s, etc. Most models can be purchased with special packages, and some professional modification companies have equipment tailored for rare models.
