Auto Brake Systems for sale The friction material of MASUMA Disc brake pads is R&D patent of the engineers in Japanese Headquarters. MASUMA Disc brake pads rely on high braking efficiency, which can be achieved by balanced heating and heat dissipation of the brake pads in different operating modes, thereby ensuring the stability of product quality, effectively reducing the noise of the brakes and discharging the dust generated by the friction between the brake pads and the brake disc. MASUMA brake pads undergo thousands of hours of cycle testing on the LINK 3900 Benching testing machine, MASUMA brake pads have advantages of wear resistance, thermal stability and low noise frequency. MASUMA N series Drum brake pads MASUMA N series Drum brake pads use a special ceramic formula, and the friction material layer is composed of ceramic fiber, aramid fiber, carbon fiber, copper fiber, high-purity graphite, potassium titanate and resin. The specified friction coefficient is 0.36, which allows for short braking distance, high temperature resistance, less dust, no noise and long life-span. Product Feature 1. MASUMA brake pads adopt the international advanced ultra-quiet ceramic formula, which effectively solves the problems of noise and dust. 2. MASUMA disc brake pads with FF level international standard friction coefficient, low noise, less dust, good braking effect. 3. The high-temperature braking ability of MASUMA disc brake pads is outstanding, Under the high temperature conditions such as continuous emergency braking and downhill braking, the friction coefficient is stable and the braking effect is good. During the actual measurement in Yunan Road testing, after 20 consecutive prolonged braking actions, the temperature of the brake disc/pad reached more than 570 degrees, but it still remained in good condition. 4. MASUMA disc brake pads use advanced ceramic formula and manufacturing process, which has the advantages of long life-span and wear resistance and can prolong the life-span by more than 25%. 5. There is more than 3000kinds of brake pads in MASUMA, meeting various worldwide car models request. Strict Testing Ensuring stable braking performance in different Road conditions, Especially in severe conditions. Brake pads' part Structurally, brake pads are composed of friction material, bottom material Layer, viscose, steel back, muffler plate and accessories. Primer layer: Improves bonding performance, reduces heat conduction, maintains consistent compressibility for thinner friction plates, reduces noise, attenuates high-frequency squeal and couple attenuate vibration. Friction material: The body material (abrasive+ lubricant) determines the friction coefficient and friction performance. The filler can reduce the cost and improve the ease of production. The binder can effectively bond various components and strengthen the fiber to enhance the mechanical strength. Friction material formula classification Brake pads on the market are mainly divided into three categories: semi-metal, less metal and non-asbestos organic matter (ceramic formula) according to different materials . Semi-metal High metal fiber(iron fiber, steel fiber, etc) content 鈮?0% Advantages: long life-span, high load, low cost. Disadvantages: low coefficient of friction, noise, wear to the brake disc, rapid aging of brake components. Less metal Lower metal fiber( Iron fiber, steel fiber, etc.) content
