The reason for the protrusion at the edge of the brake disc is the normal wear condition of the brake pads and the brake disc. Here is the relevant information: 1. The protrusion at the edge of the brake disc occurs because the brake pads are narrower than the brake disc, leading to prolonged wear that causes the edge of the disc to protrude. It is recommended to replace both the brake disc and brake pads promptly. 2. The brake disc is a crucial component of the braking system. Structurally, brake discs are categorized into solid discs and ventilated discs. A solid disc is simply a metal disc with a very straightforward design. Ventilated discs come in two types: slotted discs and drilled discs, both of which enhance the cooling performance of the brake disc.

What is the initial stopping point for reverse parking?

The initial stopping point for reverse parking is the point where you fully turn the steering wheel. Below are the precautions for reverse parking. Introduction to reversing direction: When reversing, the direction in which you turn the steering wheel determines the direction the rear of the car moves. Turning the steering wheel to the right will make the rear of the car move to the right. Whether reversing or driving normally, the movement direction of the car body is consistent with the direction of the steering wheel. When reversing, turning the steering wheel to the left will make the rear of the car move to the left, and turning it to the right will make the rear move to the right. When correcting, if the rear of the car deviates to one side, the steering wheel should be turned in the opposite direction. For example, if the car body leans to the left, you need to turn the steering wheel to the right to straighten it. Introduction to reverse correction methods: When reversing, look through the rearview mirror. If you feel the distance is wider on one side, turn the steering wheel towards that side. Therefore, if the right side is wider, turn the steering wheel to the right and observe the rearview mirror. When the car body needs to be corrected, return the steering wheel to the original position.

What is PICC's damage assessment standard for waterlogged vehicles?

The following are PICC's damage assessment standards for waterlogged vehicles: Preparation before assessment: After receiving the claim report, the insurance company staff will review the survey records, understand the accident loss situation, and inquire about the surveyor's opinions. Then, they will check the insurance coverage of the vehicle to determine the corresponding insurance type and payment limit. It is important to carefully review the claim records of the involved vehicle to avoid duplicate compensation. Damage assessment approval: Before disassembling and inspecting the accident vehicle, if the estimated loss amount exceeds the branch's assessment authority, the assessor needs to fill out the "Major Case Damage Assessment Report" and submit it to the provincial company for approval and authorization before proceeding with the assessment. Basic principles of vehicle loss: The repair scope of the vehicle is limited to the damage caused by this accident; repairable parts should be repaired as much as possible; areas that can be partially repaired should not be expanded to overall repairs; replaceable parts should not be replaced with assemblies; labor costs and spare parts prices should be accurately determined based on the difficulty of the repair process and the local labor cost level.

What is the reason for the humming sound when accelerating in fourth gear of Wuling Zhiguang?

The reasons for the humming sound when accelerating in fourth gear of Wuling Zhiguang are as follows: 1. Engine fuel pump malfunction: Damage to the engine fuel pump results in insufficient fuel supply. Even if the driver floors the accelerator, causing the engine speed to increase, the fuel injection volume remains low, leading to reduced engine output power and consequently weak acceleration. 2. Valve timing issue: Modern engines utilize CVVD valve timing systems to improve fuel efficiency. However, if the CVVD hydraulic control system is damaged, with oil leaks from sealing rings or malfunctioning CVVT, the engine's intake and exhaust will be affected, naturally reducing combustion efficiency and causing a drop in engine output torque.

How to Remove the Magotan Window Regulator?

Magotan window regulator removal steps are as follows: 1. Prepare tools and remove the door assembly; 2. Roll the window up; 3. Unscrew the window regulator fixing screws, then remove the glass; 4. Disconnect the wiring, usually the connector is located on the inner side of the door; 5. After disconnecting the wires, the window regulator can be removed. More information about window regulators: The window regulator is the lifting device for car door/window glass, mainly divided into electric window regulators and manual window regulators. Modern car door/window glass generally adopts push-button electric lifting, i.e., using electric window regulators. Electric window regulators for cars mostly consist of motors, reducers, guide ropes, guide plates, glass mounting brackets, etc. The master switch is controlled by the driver to open/close all door/window glass, while sub-switches on each door handle allow passengers to control individual window glass, making operation very convenient. The most common window issue is hardened rubber strips in the glass track or dirt accumulation, causing sluggish or stuck window movement. Therefore, regularly spraying WD-40 in the window tracks for lubrication is crucial. For rubber strips, applying lubricant maintains flexibility and reduces cracking. Another common issue is long-term wear, such as motor failure or linkage mechanism rust/breakage due to water exposure, leading to window derailment. In such cases, factory replacement of parts is necessary.
