Brake discs and brake pads do not need to be replaced together. Below is an introduction to brake discs and brake pads: 1. The replacement of brake discs depends on their thickness and wear condition. Brake discs are a crucial component of the braking system, which can be categorized into solid brake discs and ventilated discs based on their structure. 2. Brake pads, also known as brake linings, are critical safety components in a car's braking system. They consist of a steel plate, an adhesive heat insulation layer, and a friction block. Below are the maintenance methods for brake pads and brake discs: 1. Develop good driving habits. 2. Avoid emergency braking. 3. Regularly inspect brake pads and brake discs. 4. Check the thickness of the friction material. 5. Always use original equipment manufacturer (OEM) brake pads and brake discs when replacing them.

I've been driving for over a decade, and I always replace the brake pads whenever I change the brake discs—it's like buying new shoes and pairing them with new socks. The old pads can wear down the new discs, potentially causing unstable braking and, in severe cases, accidents. For example, last time I tried to save money by skipping pad replacement, the new discs developed grooves within six months, and I ended up spending more on labor to reinstall everything. Checking pad thickness during maintenance is crucial; if it's below 5mm, it's time for a replacement. Replacing both simultaneously ensures proper system break-in, reducing noise and vibration. In short, safety comes first—this advice comes from a friend who works at a dealership. Remember to inspect your braking system every 20,000 kilometers as part of regular maintenance—don't wait for problems to arise.

Do You Have to Wait 10 Days After Failing Subject 4?

Subject 4 retake must wait for ten days, and can only be scheduled after the ten-day period. Introduction to Subject 4: Subject 4, also known as the Subject 4 theory test or driver theory test, is part of the motor vehicle driver's license assessment. After the implementation of the Ministry of Public Security's Order No. 123, the Subject 3 test was divided into two parts: besides the road test, a safety and civilized driving knowledge test was added, commonly referred to as "Subject 4," which assesses "driving ethics." Retake Regulations: According to Article 44 of the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses": Each subject test can be taken once, and if the test is failed, a retake is allowed once. If the retake is not taken or is still failed, the current test session is terminated, and the applicant must schedule the test again. However, Subject 2 and Subject 3 tests must be scheduled at least ten days later. If the Subject 3 safety and civilized driving knowledge test is failed, the passed road driving skill test scores remain valid.

What is the speed range for 2nd gear?

The corresponding speed range for 2nd gear in a car is 5-20 km/h. Vehicle speed: Vehicle speed refers to the distance a car travels per unit of time, commonly referred to as speed, with units typically expressed in kilometers per hour or meters per second. Vehicle speed is one of the three key parameters used to describe traffic flow and holds significant importance in traffic flow theory research. Speed ranges for each gear: 1st gear is typically used for starting, with a speed range of 0-5 km/h; 2nd gear corresponds to 5-20 km/h; 3rd gear corresponds to 20-40 km/h; 4th gear corresponds to 40-60 km/h; and 5th gear corresponds to 60-100 km/h.
