How often do the brake pads and drums change? Up to now, many people's cars still use the front disc and rear drum brake system. How many kilometers do the drums change? Today small make-up to tell you this knowledge, so that you can quickly understand the drum brake. Drum brake piece is quite durable, in theory is a pair of two front pieces of the back piece, but the actual hand brake on the back piece of relatively large impact, so if the hand brake with good, long life! Depending on the wear and tear, disc brake is usually 50,000 km, drum brake is usually 100,000 km. Add: is to check the thickness of the front piece, generally not less than 1.5 mm, of course, if you have their own replacement capacity, you can go to 0.5 mm is no problem. Because, the limit thickness refers to a maintenance cycle of consumption can not bear the thickness. Example 7500 km consumption brake pads 0.8 mm projection, 0.5 mm is not enough to support the maintenance time of 7500, that must be replaced is the meaning. If you can change, and you know the thickness is not much, that is 4,000 when the change, should be left 0.1 mm that do not want, this is also good. Depending on the wear and tear, disc brake is usually 50,000 km, drum brake is usually 100,000 km.
