How Often Should the Brake Discs of a Motorcycle Be Replaced?

In simple terms, a motorcycle brake disc is a round disc that rotates when the motorcycle is running. The brake caliper clamps the brake disc to generate braking force. When holding the brake, the brake pad clamps the brake disc to slow down or stop. Disc brakes work well, but they are also more prone to wear than drum brakes.

We have been manufacturing motorcycle brake accessories for many years, Except universal brake master cylinder for motorcycles, we also can supply custom motorcycle brake calipers.

The following are the replacement instruction of motorcycle brake disc rotors.

1. Replacement mileage of motorcycle brake discs

Generally speaking, the brake block (that is, the two pieces in the brake caliper) needs about 20,000-30,000 kilometers to be replaced, while the replacement mileage of the brake disc is generally about 40,000-50,000 kilometers. Of course, the replacement mileage is not completely absolute, it is determined by the owner's own driving habits (whether he likes sudden braking), road conditions, maintenance cycle and other factors.

2. Conditions for replacing motorcycle brake discs

(1) In addition to the driving mileage mentioned above, if the brake block is severely worn and continues to be used, the iron block of the brake block will rub against the brake disc, and the motorcycle brake disc will soon wear out deep grooves, which need to be replaced immediately.

(2) Although the brake block is not ground to the brake disc, there are deep grooves on the brake disc due to long-term use. When the combined thickness of the deep grooves on both sides exceeds 3 mm, the brake disc needs to be replaced.

(3) Although the surface of some brake discs is smooth, they have been worn too thin. In addition, the brake pump is rusted and the brake pads are also excessively worn. At this time, not only the brake disc should be replaced, but also the brake pump should be maintained.

3. Daily maintenance method of motorcycle brake disc

After riding a motorcycle for a long time, the brake disc of the motorcycle will generate a lot of heat under braking, so do not wash the car immediately after riding the motorcycle for a long time, you should turn off the engine to reduce the surface temperature of the brake disc, and prevent the high temperature brake disc from being exposed to cold water and heat. Expansion and contraction produce deformation. It is also necessary to prevent the rock from hitting the brake disc and causing deformation. After locking the rim, forgetting to unlock the vehicle and starting the vehicle will easily lead to the deformation of the brake disc. When the brake disc is deformed, a friction sound in one direction will be produced.

In addition, the best way to improve the life of the brake disc is to maintain good driving habits and try to avoid sudden braking and sudden stop. Diligently clean up the sand on the brake disc, and often check whether the brake pad is worn to the point of contact with the brake disc.

We Jumpo supply a variety of motorcycle brake discs, which can be customized, only need customers to provide drawings or samples. Our available diameters are 160mm, 180mm, 190mm, 220mm, 240mm and 290mm. If you are interested in our products, welcome to consult online!
