Generally, the front drum brake drum brake vehicle is more than 20,000 yuan more expensive than an ordinary vehicle. Users who purchase a car can use this to determine whether the car's price is reasonable. The following is the definition of disc brakes and drum brakes
Using a metal block (dish) instead of a drum, there is a flat brake shoe on both sides of the brake disc. When the oil pressure from the brake master cylinder is pumped to the sub-cylinder, the brake shoe is clamped to the brake disc to achieve tight braking. The effect has been widely used in the front wheels. Some high-end vehicle devices have four-disc brakes. Their advantages are that they are sensitive, heat dissipation is good, there is no need to adjust the brake gap, and maintenance is easy.
A drum brake is a brake device that utilizes a stationary brake pad in a brake drum to rub a brake drum that rotates with the wheel to generate a friction force that reduces the rotational speed of the wheel.
When the brake pedal is depressed, the force of the foot will cause the piston in the master cylinder to push the brake fluid forward and generate pressure in the oil circuit. The pressure is transmitted to the brake cylinder piston of each wheel via the brake oil. The piston of the brake cylinder then pushes the brake pad outward, causing friction between the brake pad and the inner surface of the brake drum, and generating enough friction force to reduce the rotational speed of the wheel. To achieve the purpose of braking.
Tanker vehicles must front and back drums before they can attend
The front and rear drums are often referred to as front drum brake drum brakes. At present, dangerous vehicles must be front brakes, rear drum brakes, etc. to be able to attend households including tanker refuelling trucks, etc.
