Analysis and solution of common problems of brake friction pads (2)
Why does braking lag occur?
The possible causes of brake hysteresis are: brake return spring failure, improper clearance between brake friction disc and brake disc or too tight assembly size, brake friction disc thermal expansion performance is not qualified, and parking brake return is poor.
Why smoke when braking?
The brake friction sheet contains about 20% organic matter, which will decompose and smoke when the temperature is too high, and form a layer of oily material on the surface of the friction sheet, affecting the braking effect. The possible reasons for this phenomenon are: frequent braking in the downhill, causing the temperature to be too high and smoke; The content of organic matter in the formula of brake friction sheet is unqualified and exceeds the standard.
Why does the back plate of the brake friction plate come off?
There are two cases when the backplane of the brake friction plate falls off. One is that there is a crack between the backplane and the friction material; Second, the friction material itself produces cracks. The possible reasons are: the early treatment process of the backplane is poor, the stability of the friction material is poor, the pressing process is not qualified, the quality of the adhesive is poor, the use temperature is too high, the incorrect installation, impact and knock.
What is the role of the groove in the brake friction plate?
The function of the inner slot of the brake friction plate is to discharge gas, reduce noise and change the natural frequency of the product, discharge the abrasive dust, and enhance the adhesion degree of the friction material and the backplane.
