Car brake pads make noise due to the following reasons: 1. Metal hard spots can cause abnormal sounds; 2. Severe wear—the warning piece will make abnormal sounds to prompt replacement; 3. The brake disc and pads are in the break-in period; 4. Foreign objects between the brake pads and disc; 5. Improper installation; 6. Poor return of the brake caliper. Brake pads, also known as brake linings, refer to the friction materials fixed on the rotating brake drum or disc of the wheel. The friction linings and blocks withstand external pressure to generate friction, thereby achieving the purpose of vehicle deceleration. Their components include: 1. Steel plate; 2. Bonded heat insulation layer; 3. Friction block.

How to Tell if the Transmission Mount is Broken?

When the transmission mount is broken, you will clearly feel the steering wheel shaking during engine idle operation; you will also distinctly feel vibrations when sitting on the seat; however, there will be no fluctuation in RPM, and you can perceive engine vibrations. During driving conditions, abnormal noises may occur when accelerating or decelerating sharply. Below are the symptoms of a broken transmission mount: 1. Automatic transmission vehicles: You will feel a mechanical impact sensation when shifting into drive or reverse gear. 2. Abnormal noises: The vehicle will produce abnormal noises from the chassis during starting and braking. 3. The role of the engine mount rubber: The engine mount rubber is a crucial component connecting the engine to the vehicle body.

Should the heel touch the ground or stay suspended when pressing the clutch in Subject 2?

When pressing the clutch in Subject 2, the heel should touch the ground. Below are the precautions for pressing the clutch in Subject 2: 1. Movement: The correct posture for pressing the clutch is to use the ball of the foot, and during the process, the entire foot should move with the clutch pedal, rather than keeping the heel fixed in place. 2. Feel the vehicle vibration: Once the clutch reaches the semi-engagement point, you can feel the engine vibrating. When there is slight vibration, you can release the brake to start moving, as the speed at this point is ideal for the test. However, during a hill start, you should wait until the vehicle vibrates noticeably before releasing the brake. Otherwise, the vehicle may not have enough power to climb the slope and could roll backward once the brake is released.
