Below are three common ways of judging it. After stopping, touch the brake drums of each wheel with your hand. If all the brake drums are heating up and the degree of heating is similar, then the fault of not returning to the original position is that the master cylinder does not have free travel when wearing the brake pedal. If only a few wheels are heating up, the fault lies in the brake of that wheel. When all the wheels of the car are overheating, the free stroke of the brake pedal should be checked first. If the free travel is normal, the main cylinder oil storage chamber cover can be opened, and the brake pedal can be continuously pressed and released.

See if it can return oil. If the oil cannot be returned, it is because the oil return hole is blocked. If the oil return is slow, it is because the leather bowl and leather ring are swollen and the return spring is weak. The brake master cylinder should be removed, inspected, and repaired. If the brake pedal cannot return quickly, it indicates that the pedal return spring is too soft and broken, and should be replaced. If the fault lies in the wheel brake, the hot main wheel can be lifted up with a jack, and the wheel cylinder release screw can be loosened first. At this time, the brake fluid is rapidly sprayed out, and the wheel immediately rotates freely, indicating that the brake pipeline of the wheel is blocked.

The wheel cylinder cannot return oil, so the oil passage should be unblocked. If you still feel dragging when turning the wheels, you can check whether the gap between the friction plate and the brake drum is too small. If all the above situations are normal, the brake drum should be removed and the cylinder piston cup should be carefully inspected for any induced stagnation or expansion, whether the return spring is ineffective, whether the brake shoe support forging is free of oil induced jamming shoes, and then necessary repairs should be carried out according to the situation. The above three are the judgment methods for hydraulic brakes when they do not return to their original position, and the faults are eliminated through sequential judgment.

Timely maintenance and replacement are carried out to ensure driving safety.nHydraulic brakes should be able to reduce the vehicle's speed and stop within a specified distance when the brake pedal is fully depressed once. At the same time, when stepping on the pedal, keep it off the floor of the cab5If it is over centimeters, it cannot be stepped on anymore (commonly known as hardened). When stepping rapidly continuously (taking the second step without releasing the pedal), the pedal should be higher each time, but when stepping slowly continuously (taking the second step immediately after releasing the pedal), the pedal cannot be raised.

If this requirement cannot be met, inspection and repair should be carried out separately for different situations. If there is a vacuum booster device, it should be deflated first to accurately check the condition of the hydraulic system. There are several air release screws on the vacuum booster, and the air should be released one by one according to the regulations of each booster. If the car does not slow down after stepping on the brake pedal, it is considered to have completed braking
