The causes of brake pulsation and vibration include uneven wear of the brake disc or damage to brake components. Below are the specific reasons for brake pulsation: Uneven Disc Wear: If the outer side of the brake disc is thicker than the inner side or vice versa, during braking, the brake pads clamp the disc vertically. If the disc is uneven and does not fully contact the pads, it will cause vibration. The higher the speed, the more severe the vibration, making it harder to stop the vehicle. Damaged Brake Components: If you feel the brake vibrating when applying the brakes, especially at high speeds on highways, it indicates that the surface flatness of the brake disc or pads is off. Loss of brake elasticity can involve damage to many components.

Why Does the Buick Regal Depreciate Quickly?

There are many reasons why the Buick Regal depreciates quickly. Here is a detailed explanation of the Buick Regal's rapid depreciation: 1. Reasons for rapid depreciation: In recent years, American cars, particularly their transmission tuning, have been subpar, with frequent occurrences of jerking and oil leaks, casting a shadow over the reputation of American vehicles. Additionally, the frequent use of heavy discount marketing strategies has kept the resale value of the Regal consistently low. 2. Advantages of the Buick Regal: Compared to its aggressive exterior, the interior of the Regal appears much more 'restrained.' The overall design language remains distinctly Buick, with interior details like red stitching blending a homely feel with a touch of sportiness. The layered interior design enhances the sense of depth inside the car, while the newly equipped button-style gear shift saves considerable space and adds a technological touch.
