Reasons for brake failure to return to position: Brake return spring broken or lost elasticity: Replace the brake pedal return spring. Brake caliper piston seized: Brake caliper piston seizure causing braking resistance. Rear axle issues: Rear axle bearing fixed or installed incorrectly, or rear wheel bearing worn. Dirty brake fluid: Brake fluid is highly hydrophilic and easily absorbs moisture from the air. If not replaced in time, it will contain excessive impurities and moisture, affecting the transmission of braking force. Rubber aging: Due to prolonged inactivity, the edges of the rubber and guide sleeve may stick together, causing the rubber sleeve to be cut or squeezed at the edges. Rubber fragments hinder smooth movement. Lubricating oil accelerates rubber softening and aging, causing the rubber sleeve to elongate when inserted into the guide sleeve and compressed, making it more prone to sticking or jamming at the edges.

What is the reason for engine shaking but not stalling when a vehicle wades through water?

Vehicle wading through water causes engine shaking but not stalling for the following reasons: 1. Engine air filter element: When the vehicle enters water, a small amount of water enters the high-voltage wires, causing the engine air filter element to get wet. This increases intake resistance and allows water to enter the combustion chamber, leading to poor ignition system performance. 2. Exhaust: It could also be due to wading too deep, where water affects the exhaust outlet, impacting exhaust flow. The engine didn't stall probably because no water entered it. 3. Precautions: Avoid lifting the throttle to prevent water from entering the exhaust pipe and causing stalling. If the engine stalls midway, do not attempt to restart it or tow the vehicle in gear. Only tow it back to the repair shop in neutral.

Can I still get my car inspected if it's two months overdue for the annual inspection?

You can still get your car inspected if it's two months overdue for the annual inspection, but you should do it as soon as possible. Regulations: According to the laws and regulations of the traffic management department, if the owner of a vehicle does not participate in the annual inspection after the expiration date, the insurance company will not be liable for compensation in the event of a traffic accident. Exemption policy: Registered private cars that meet the conditions can enjoy the exemption policy and only need to be inspected once a year. Vehicles aged 6 to 15 years must undergo an annual on-site inspection, while vehicles over 15 years old must be inspected every six months. For commercial passenger vehicles, inspections are required once a year within the first 5 years and every 6 months thereafter. For trucks and large or medium-sized non-commercial passenger vehicles, inspections are required once a year within the first 10 years and every 6 months thereafter. Time regulations for annual inspection: The first annual inspection for a small car is required when it reaches six years of age. Non-commercial small and micro passenger vehicles, including family cars over 6 years but under 10 years old, need to be inspected every two years. For a car that has just reached six years, you need to drive the vehicle to the inspection station with your ID card, vehicle license, vehicle and vessel tax or tax exemption certificate, and compulsory traffic insurance policy. After passing the inspection, you will receive a certificate, which you then take along with the other documents to the relevant window to obtain the annual inspection sticker.
