What Causes Brake Pad Noise at Low Speeds?

Brake pad noise at low speeds can be caused by brake pad break-in, sand particles entering, brake system malfunctions, severe brake disc wear, and other factors. The details are as follows: Brake Pad Break-in: Brake pad break-in is a crucial phase for new cars. It usually takes a few hundred kilometers of driving before the brakes feel more comfortable. Newly replaced brake pads require a break-in period to better integrate with the brake discs. Initially, they may feel stiff, and noise during this period is normal. Sand Particles Entering: While driving, very fine sand particles may enter between the brake pads and discs, sometimes causing noise due to friction. This usually doesn’t require repair—simply driving for a while can help the particles fall out. Brake System Malfunction: If the noise is accompanied by brake system failure, inspection and repair are necessary. Missing or damaged brake disc screws or insufficient lubrication can also cause brake noise. Severe Brake Disc Wear: Abnormal brake disc wear can occur due to dirty disc surfaces, uneven material density, excessively high operating temperatures, or mismatched installation torque. If deep grooves appear on the brake disc, it must be replaced.

What is the Difference Between Full Synthetic and Semi-Synthetic Engine Oil?

The differences between full synthetic and semi-synthetic engine oil lie in the base oil, replacement cycle, and applicable vehicle conditions. The specific details are as follows: Base Oil Difference: Full synthetic oil is blended from Group III, IV, and V base oils; semi-synthetic oil uses Group III base oil. Replacement Cycle Difference: Full synthetic oil should be replaced once a year or every 10,000 kilometers during use; semi-synthetic oil should be replaced every six months or every 7,500 kilometers. Applicable Vehicle Conditions Difference: Full synthetic oil is more commonly used in turbocharged engines and high-end luxury vehicles; semi-synthetic oil is more suitable for economical, small-displacement vehicles that prioritize smooth driving.

How to Align the Timing of a Car Engine?

The common method involves locating the top dead center of the first cylinder piston and aligning the relevant marks on the crankshaft or flywheel and cylinder block to the appropriate positions. Below is a detailed introduction to car engine timing: Timing: It refers to the specific positional relationship between the movement of the engine pistons and the valves, ensuring that both movements remain synchronized. Timing Belt: An essential component of the engine's valve system, it connects to the crankshaft and ensures accurate intake and exhaust timing with a specific gear ratio. It has a longer service life, more mature technology, lower cost, and less noise but requires regular inspection and maintenance. Timing Chain: It features compact structure, high power transmission, high reliability and wear resistance, and is maintenance-free for life. However, compared to traditional timing belts, it produces more noise.

Disadvantages After Replacing the Steering Gear?

When the steering gear encounters certain issues, replacement is sometimes necessary for resolution. However, after replacement, symptoms such as heavy steering, abnormal noises, or vehicle deviation may occur. Below are relevant details about replacing the steering gear: Issues after replacing the steering gear: Abnormal noises after replacing the steering gear are normal. They might be bothersome initially but will gradually diminish over time. Heavy steering and deviation issues are often related to installation techniques and may depend on the repair shop you choose. If you opt for a reputable and guaranteed 4S shop or a large repair facility, the likelihood of such problems is significantly reduced. Whether to replace: Deciding whether to replace the steering gear should be based on professional advice from maintenance personnel. While they often recommend direct replacement, this recommendation may not only stem from genuine fault factors but also involve certain profit considerations.
