Why Does the Car Body Shake Violently When Braking?

What Causes the Brake Pedal to Be Hard to Press?

The reasons why the brake pedal is hard to press are: 1. The car's vacuum booster pump is leaking or malfunctioning: Without the booster, the brake pedal becomes difficult to press; 2. The brake was pressed after the engine was turned off: The brake booster pump only generates vacuum when the engine is running. When the engine is off, it relies on the residual vacuum, which depletes after a few presses. However, it will restore once the engine is started, and this is not a malfunction. The brake pedal is the pedal that restricts power, i.e., the pedal for the foot brake (service brake), used for deceleration and stopping. The working principle of the brake pedal: A wheel or disc is fixed on the high-speed shaft of the machine, and a corresponding brake shoe, band, or disc is installed on the machine base. Under external force, it generates braking torque.

Why does the Envision make noise when releasing the brake?

When the Envision makes noise while releasing the brake, it may be due to new parts needing a break-in period, foreign objects in the gaps between parts, poorly fixed brake calipers or discs, or severe wear on the brake discs. Break-in period required: Replacing new friction pads or new brake discs may result in noise if the new brake discs cannot properly break in with the friction pads immediately. Foreign objects: Hard substances like gravel entering the gap between the brake disc and brake pads can also cause noise. Poorly fixed brake calipers or discs: Poor fixation of brake calipers or discs is another cause of brake noise and can also lead to uneven brake wear. Severe wear: Excessive wear on the brake discs or cracks in the brake pads, even if not heavily worn, can also cause brake noise.

How to adjust the time on a Camry?

Method to adjust the time on a Camry: 1. Turn the key to the ACC position or remove it, rotate the light switch to turn on the parking lights; 2. Press and hold the instrument button until the hour zone on the instrument panel starts flashing, release the button and press it again, each press increases the hour by one; 3. After adjusting the hour, do not press the button, the hour will flash 5 times and automatically switch to minutes, each press of the button increases the minute by one, after adjustment, do not press the button, the minute count will flash 5 times and then stop. Taking the Camry 2021 2.0E Elite Edition as an example: It is a mid-size car launched by GAC Toyota, with a length, width, and height of 4885mm, 1840mm, and 1455mm respectively, a wheelbase of 2825mm, equipped with a 2.0L naturally aspirated engine, matched with a CVT continuously variable transmission (simulating 10 gears).

What Causes the Abnormal Noise When Reversing in a BMW 525?

BMW 525 experiencing abnormal noise when reversing is primarily due to abnormal retraction of the brake caliper piston, friction noise caused by rust on the brake disc, and reversing noise caused by a faulty handbrake system. Abnormal retraction of the brake caliper piston: The generation of vehicle braking mainly relies on the tight contact between the brake pads and the brake disc, creating friction. The movement of the brake pads is facilitated by the thrust formed by the movement of the piston in the brake caliper. This is the reverse reasoning of the braking process. Solution: After braking is completed, use the accessories in the brake caliper. Friction noise caused by rust on the brake disc: Rust on the brake disc is a very common phenomenon, especially after driving through water. If parked for no more than two days, small rust spots will appear on the brake disc. Solution: It is recommended to go to an auto repair shop to remove the rust with sandpaper.

How Many Kilometers Should a Scooter's Spark Plug Be Replaced?

Scooters require spark plug replacement every 30,000 kilometers. The spark plug is a component of the ignition system and needs regular replacement. Spark Plug Replacement Interval: Under normal maintenance conditions, spark plugs should be replaced after 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type. It is recommended to follow the user manual. The following standards can be referenced for maintenance replacement: Platinum spark plugs should be replaced at 40,000 kilometers, standard nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. Steps for Replacing Spark Plugs: Open the engine hood and lift the plastic cover of the engine. Remove the high-voltage distributor wires, marking each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for external debris such as leaves or dust and ensure they are thoroughly cleaned. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the high-voltage distributor wires in the firing order and secure the cover.

What are the reasons for the small sunroof leakage in the Audi A6L?

The reasons for the small sunroof leakage in the Audi A6L are threefold: blockage of the sunroof drainage holes, improper sealing between the sunroof and the sealing strip, and aging of the sealing strip. Blockage of the sunroof drainage holes: Solution: First, check if there is any dirt such as dust, leaves, or small twigs in the sunroof drainage holes. If the drainage holes are blocked, clearing them should resolve the issue. The drainage holes are typically located at both ends of the guide channels on either side of the sunroof. Improper sealing between the sunroof and the sealing strip: Solution: Inspect whether the sunroof and the sealing strip are properly sealed. If not, press the sealing strip firmly with your hand during reattachment to ensure a tight seal. If you prefer not to do it manually, you can also visit a 4S shop for assistance. Aging of the sealing strip: Solution: Use a new sealing strip and adhesive to reseal the sunroof. Carefully remove the old sealing strip along its track, then clean the area with a cloth. Apply the adhesive along the edge of the sunroof, then attach the new sealing strip along the track of the sunroof edge.
