Air brakes becoming hard is due to a malfunction in the gas booster system of the master cylinder. Below is an introduction to air brakes: 1. Introduction: Air brakes are a type of braking system. In automobiles, a series of specialized devices that apply a certain force (primarily on the wheels) from the external environment (mainly the road surface) to enforce a certain degree of braking are collectively referred to as the braking system. Automotive braking systems can be categorized based on their functions into service brakes (air brakes), parking brakes, emergency brakes, and auxiliary brakes. Parking brakes can further be divided into central disc brakes and spring brake actuators, with the latter commonly known as "spring brakes." 2. Composition: A standard air brake system consists of a brake control mechanism, dual-circuit brake mechanism, central disc brake mechanism, brake assembly, air compressor, etc. The brake control mechanism includes components such as the brake pedal and pedal suspension; the dual-circuit brake mechanism includes the air reservoir, brake valve, low-pressure alarm, pressure regulator, brake lines, directional valve, relay valve, safety valve, and drain valve; the central disc brake mechanism includes the parking brake control handle, brake cables, and central disc brake assembly.

How to Use the M Gear Shift?

The usage method of the M gear shift is as follows: 1. When using the manual shift mode, you need to switch the shift lever to the "M" position. While driving, you can directly shift into the M gear. Additionally, in manual mode, when the vehicle brakes or decelerates, the transmission will automatically downshift. The driver does not need to manually downshift unless encountering a situation that requires forced downshifting (such as accelerating to overtake). 2. When overtaking, if in D gear, you can only sequentially upshift to overtake. However, when switched to M gear, stepping on the accelerator allows the vehicle to utilize the high torque of lower gears to instantly accelerate, completing the overtaking action more quickly.

What Causes the Electric Car Seat to Stop Responding?

Generally, electric seats rarely malfunction unless they are adjusted too frequently during use, which can cause issues with the seat tracks or motor. Common seat malfunctions typically manifest in the following ways: 1. The electric seat gets stuck or jammed, usually due to oxidation or insufficient lubrication of the seat adjustment linkage. 2. The seat suddenly stops working and fails to function properly. This is often caused by wiring issues. You can check if the fuse is faulty and then inspect whether the seat motor is functioning normally. 3. The seat sometimes fails to move into the desired position during use. This is usually caused by blockage or lack of lubrication in the adjustment linkage or slide rails, leading to jamming and preventing full movement.

How to Adjust Camber Angle?

Wheel camber angle can be adjusted through the following methods: 1. Adjust the tightness of the wheel hub bearing. 2. Replace the worn-out kingpin and its bushings. 3. Replace the steering knuckle with incorrect knuckle angle. 4. Remove the front axle for deformation inspection and correction. 5. Adjust the shims between the upper control arm shaft and the fixed frame. Extended information: The functions of wheel camber angle are: 1. It allows the wheels to roll close to perpendicular to the road surface, reducing sliding and steering resistance, making steering easier. 2. It reduces the load on bearings and lock nuts, increasing service life and improving safety. 3. It works in conjunction with toe-in to prevent tire wear. 4. When there is directional deviation, the front wheels can automatically return to the straight-ahead position.

Does the Battery Charge When the Vehicle is Idling?

When the vehicle is idling, the battery does get charged. The engine directly drives the alternator via a belt, and once the engine starts, the electricity generated by the alternator is rectified and voltage-regulated before being used to charge the car battery. Below are the potential harms of prolonged idling to the vehicle: 1. Fuel Consumption: The vehicle consumes fuel while idling. 2. Exhaust Emissions: During idling, the amount of exhaust gases in the engine cylinders increases, leading to higher emissions. 3. Increased Accident Risk: If the engine remains idling for extended periods, the vehicle's braking system may loosen, increasing the risk of unintended rolling. 4. Risk of Damaging the Catalytic Converter: Prolonged idling causes the engine to produce excessive exhaust gases. Unburned fuel mixture may ignite at the catalytic converter, potentially damaging it.
