Abnormal noise from brake pads during startup can occur due to rain or other conditions that cause water to adhere to the brake discs. When the vehicle is left parked for a period, the surface of the brake discs can rust. Below is an introduction to brake pads: 1. Introduction: Brake pads are also known as brake linings. 2. Function: In a car's braking system, brake pads are the most critical safety components. The effectiveness of all braking performance is decisively influenced by the brake pads, making high-quality brake pads the guardian of both the driver and the vehicle. 3. Material: Brake pads (brake-lining) are generally composed of a steel plate, an adhesive heat insulation layer, and a friction block. The steel plate is coated to prevent rust, with the coating process monitored using an SMT-4 furnace temperature tracker to ensure quality by detecting the temperature distribution during coating. The heat insulation layer is made of non-heat-conductive materials to provide thermal insulation. 4. Principle: The friction block consists of friction materials and adhesives. During braking, it is pressed against the brake disc or drum to generate friction, thereby achieving the goal of decelerating the vehicle. Due to friction, the friction block gradually wears out. Generally, the lower the cost of the brake pads, the faster they wear out.

How often is the vehicle license reviewed?

Different types of motor vehicle licenses have different review periods. For commercial passenger vehicles, the license is reviewed annually for the first five years, and every six months thereafter. For large and medium-sized trucks, the license is reviewed annually within the first ten years, and every six months after ten years. Small non-commercial cars and motorcycles are exempt from on-site annual reviews for the first six years, and then reviewed biennially from six to ten years. Vehicle license annual review process: Required documents: Original and copy of the vehicle license, proof of vehicle and vessel tax, original insurance card, original ID card. Check online for any traffic violations and ensure they have been resolved. Self-service procedure: Obtain the annual review form from the driving association and get it stamped; take the form to the local traffic police team for another stamp. Then, take the form to the vehicle inspection line entrance for signing, enter the inspection line, and undergo vehicle checks including front and rear brakes, parking brake, emissions, lights, and horn sound. After inspection, proceed to the engine model number check. Collect the inspection results form in the office and pay fees for any failed items, re-inspection, and model number check. Finally, with the annual review form, inspection results form, and vehicle license, collect the vehicle inspection certificate and have the license printed with the new validity period. Submit the annual review form and inspection results form to the local vehicle management office for archiving, and replace the old road and bridge IC card with a new one.

What is the wading depth of the Jeep Compass?

The maximum wading depth of the Jeep Compass is 480mm. The wading depth of the Jeep Compass is determined by the height of the vehicle's chassis, which is the ground clearance listed in the model's parameter configuration table. Generally, the greater the ground clearance, the higher the chassis, and the higher the safety factor when passing through waterlogged roads. Therefore, in terms of safe wading depth, the advantages of off-road vehicles and SUVs are obvious. However, for most compact and small cars with low chassis, the position of the vehicle's air intake should be used as a benchmark when passing through waterlogged roads. If the air intake of the Jeep Compass is below the water level while wading, water will be sucked into the engine's cylinders. Since water cannot be compressed like air, it can cause severe damage to the engine's mechanical components (such as connecting rods, pistons, crankshafts, etc.). Therefore, the wading depth must not exceed the height of the engine's air intake. Alternatively, the height of the engine's air intake (and thus the maximum wading depth) can be increased by installing a snorkel. If wading is unavoidable, the following safe and correct operations should be performed: Before wading, always turn off the auto start-stop function to prevent the engine from automatically restarting after stalling in water, which could cause severe damage due to water ingress; Assess the underwater road conditions based on the passage of preceding vehicles and choose an appropriate entry point. Observe the path taken by other vehicles and follow their tracks at low speed, avoiding sudden acceleration or deceleration; On waterlogged roads, use warning water level markers, trees, or the wheels and doors of other vehicles as reference points to estimate the water depth before deciding whether to proceed; Know your vehicle's safe wading depth. If the water depth exceeds half the tire height or the engine's air intake, avoid entering the water and choose an alternative route.
