Vehicles need daily maintenance, such as tires can be used for 4 to 5 years or run 100,000 kilometers, the oil needs to be replaced regularly, the brake pads are the same, the brake pads are the most critical parts of the entire vehicle braking system, directly related to personal safety.
Whenever you press the brake pedal, a hydraulic clip called a brake caliper squeezes a pair of brake pads, causing friction between the brake pads and the heat energy generated by the friction to slow down or stop the car.
Several factors of accelerated brake pad wear
Every time the brake, the brake pad and the brake disc contact, there will inevitably be a certain wear, if the brake pad wear faster, it is generally because: frequent braking, sharp braking, hard braking.
Different vehicles use different types of brake pads. Different driving habits will also affect the choice of brake pads, do you pursue high performance or comfort, often run long distances or run in the city?
High performance: high friction coefficient, high temperature resistance, high speed, high temperature driving process performance is outstanding, braking effect and braking comfort is good.
Safety: low thermal decline, good recovery performance, mountain roads and high temperature, high temperature braking performance is not reduced.
Comfort: Comfortable braking, no noise. Pollution-free, balanced braking.
Common brake pads are: semi-metallic brake pads, asbestos-free organic brake pads, ceramic brake pads
Organic brake pads
Organic brake pads (or NAO brake pads) are usually made from small amounts of metal, vegetable fibers, carbon, or even Kevlar blend resin. There is also a type called NAO low metal brake pads
Organic brake pads are usually the most cost-effective option. The advantages of stable brakes, no damage to brake discs, low noise, etc., but in daily driving, their wear speed is faster than other types of brake pads, and they are easy to produce ash, and because they are softer, the braking performance response may not be so good, the heat resistance is poor, so it is not a very good choice.
Semi-metallic brake pads
Brake pads made of metal fiber as the main reinforcing material, formulated with an iron fiber/iron powder content of more than 50 wt%. Semi-metallic brake pads have the strongest braking capacity, they have the widest operating temperature in these three brake pads, but like organic brake pads, they produce large brake dust and are also the loudest brake sound. The damage to the brake discs is also relatively large. But they are well suited for heavy vehicles.
Ceramic brake pads
Most of the ceramic brake pads are composed of reinforcing fibers, iron-free fillers, binders and a small amount of metal, and the reinforcing fibers include mineral fibers, aramid fibers and functional ceramic materials represented by potassium titanate whiskers. They have the longest service life, quiet and stable braking performance, providing stronger performance than organic asbestos-free brake pads, but without generating a lot of brake dust, and because they are ceramic, heat dissipation is better than other brake pads.
Brake pads should still be selected according to their own driving situation and driving habits.
