Essentials of brake pedal operation

1. Slow braking: Press the clutch pedal while releasing the accelerator pedal, push the gear lever to the low gear position, then lift the clutch pedal and quickly place the right foot on the brake pedal. Gradually press the brake pedal according to the required speed and parking distance until it stops.

The working principle of the brake

Use the mutual friction between non rotating components connected to the vehicle body (or frame) and rotating components connected to the wheel (or transmission shaft) to prevent the rotation or tendency of the wheel. A brake is a device that has the function of slowing down, stopping, or maintaining a stopped state of moving parts (or moving machinery). The brake mainly consists of a brake frame, brake components, and control devices, and some brakes are also equipped with automatic adjustment devices for brake component clearances. In order to reduce braking torque and structural dimensions, brakes are usually installed on the high-speed shaft of equipment, but large equipment with high safety requirements (such as mine hoists, elevators, etc.) should be installed on the low-speed shaft near the working part of the equipment.

Disc and drum brake systems for motor vehicles

The function of the car braking system is to slow down or stop the driving car according to the driver's needs, maintain a stable speed for downhill driving, and keep the stopped car in place. According to the timing of the braking system, it can be divided into service braking system, parking braking system, emergency braking system, and auxiliary braking system. According to the braking control energy, the braking system can be divided into manual braking system, power braking system, and servo braking system. According to the transmission mode of braking energy, braking systems can be divided into mechanical, hydraulic, pneumatic, electromagnetic, and combination braking systems. The automotive braking system mainly consists of four parts, namely energy supply device, control device, transmission device, and brake.

How to repair brake shoes and friction plates

By using visual and percussion methods, the brake shoes and their friction plates should be free of cracks. The brake shoes should be inspected according to the sample plate. If they are bent, twisted, or deformed slightly, they can be corrected by cold pressing. Use a vernier caliper depth gauge to measure the distance between the rivet head of the friction plate and the surface of the friction plate, which should not be less than 0.80mm. The thickness of the lining should not be less than 9mm. Otherwise, replace it with a new lining or brake shoe assembly. If the friction plate has light oil stains and only a small amount of wear on the lining, gasoline can be used to clean the oil stains. After cleaning, it must be heated and dried, and then smoothed with a file and coarse sandcloth. The fitting area should be measured with the brake drum surface, and it must meet technical standards. It is allowed to continue using.

What is the function of the brake shoe assembly

The function of the moving shoe assembly is to withstand the thrust of the actuator, the normal and tangential forces of the brake drum, and the support reaction force. It is a friction couple component of a drum brake, which not only has the strength and stiffness required as a component, but also has the highest and stable friction coefficient possible, as well as appropriate wear resistance, heat resistance, heat dissipation, and thermal capacity.

What are the precautions for replacing a brake vehicle

1. When choosing brake pads, it is still important to choose a high-quality brand that can be used with ease. Don't be too greedy for cheap. Once the goods are ready, the price won't be very low.

How often are drum brake pads replaced?

It is generally recommended to replace the drum brake pads every 60000 kilometers. The situation to determine whether the brake pads need to be replaced is as follows: 1. Usually, a new pair of brake pads has a thickness of approximately 1.5cm. If the thickness of the brake pads is less than 0.5cm, it is necessary to consider replacing them.

What is the difference between disc brake pads and drum brake pads?

The braking system of a car is one of the key components to ensure driving safety, and the most important one is the brake pads. Brake pads are divided into disc brake pads and drum brake pads, which have different structures and working principles.

Why do brakes react slowly

Why do brakes react slowly? There are probably the following aspects: (1) The pedal is too far to travel freely. (2) The brake fluid in the brake master cylinder is too low, or the hole is blocked by impurities, causing the master cylinder parts to age, swell, or even deform or be knocked over.
