What Is the Working Principle of Motorcycle Brakes?

The brake system plays a very important role in motorcycles. When you are riding, the brakes suddenly do not work or the brakes are locked directly, which is a fatal danger. If the thickness of the motorcycle brake pad is less than 2mm, you should be prepared to replace it.

Two Types of Motorcycle Brake Systems

The brake is a device that slows down or stops a motorcycle. Braking methods are mainly divided into disc brakes and drum brakes. Both types of friction brake devices use friction to generate braking force.

Disc brakes are divided into ordinary disc brakes and ventilated disc brakes. Ventilated disc brakes have many circular ventilation holes drilled on the disc surface, or cut ventilation slots on the end surface of the disc or prefabricated rectangular ventilation holes. Ventilated disc brakes use the effect of air flow, and their cooling and heating effects are better than ordinary disc brakes.

The working principle of the disc brake system is to install a disc that rotates synchronously with the wheel on the motorcycle wheel hubs, install a caliper on the front fork and the frame, and then clamp the disc with the brake block in the caliper. Disc brakes refer to a brake system that uses gold discs instead of drums.

Disc brakes use stationary brake discs to clamp the brake discs that rotate with the tires on the wheels to generate friction and reduce the rotation speed of the wheels. When the motorcycle rear brake pedal is stepped on, the piston of the brake master cylinder will be pushed. Disc brakes have better heat dissipation than drum brakes. When the brakes are continuously stepped on, it is less likely to cause the brakes to decline and cause the brakes to fail. The thermal expansion of the brake disc in the thickness direction is extremely small, and the change in size after heating does not increase the stroke of the brake pedal.

The brake pads of the disc brake system can be judged by the groove, or taken out from the caliper to check whether the thickness is sufficient. As the hub brake system is difficult to take out, it can be judged by the brake rocker knob. If the knob can be easily adjusted to the end and there is no braking force when the brake is used, it means that the brake pads should be replaced. In addition, you can also check whether the brake pads are still sufficient by replacing the tires.

Drum brakes can be seen everywhere on some 125CC car bodies. The advantage is low cost, simple and convenient maintenance method. However, the braking effect is poor and overheating will affect the braking effect. It is mostly used for small displacement and low price motorcycles and rear brake motorcycles.

Maintenance of Brake Pads

In order to prevent dust from adhering to the discs or brake pads, we can purchase brake cleaners by ourselves. Simple cleaning and maintenance can ensure that the brake pads operate normally.

Never use oil or lubricants! These ingredients will be absorbed by the brake pads, resulting in reduced braking performance and increased driving hazards!

In addition, the determination of the minimum thickness of brake pads also depends on many factors, mainly including the situation of the brake system itself, the type of brake pads, the assembly of the brake pads and brake shoes, etc.
