Will Applying Oil on Brake Discs Be Discovered?

2 Answers

Applying oil on brake discs is an act that should never be performed, regardless of whether it will be discovered or not, as it can lead to severe consequences. Below are the relevant details: Consequences: Oil stains can cause braking slippage during braking, which can easily lead to accidents. The standard procedure is to clean the surface with carburetor cleaner, let it dry, and then sand the contact surface with sandpaper. If engine oil spills onto the belt during an oil change, the belt will slip, and it will only function properly once the oil is removed. Introduction to Brake Pads: Brake pads, also known as brake linings, are the most critical safety components in a car's braking system. The effectiveness of all braking relies decisively on the brake pads, making high-quality brake pads the guardian of both the driver and the vehicle.

I've been repairing cars for many years and have seen numerous cases of problems caused by oil on brake discs. Oil makes the disc surface slippery, leading to squeaking or skidding during braking, which is very easy to detect. A quick inspection will reveal the oily sheen or a burnt smell. I've handled several cases where owners thought they were preventing rust, only to end up with longer braking distances and nearly causing accidents. Next time you take your car to the shop for maintenance, the technician will immediately spot it by wiping with a cloth or testing the brakes. I must also warn you that this practice damages the disc material and accelerates rust and corrosion. If you accidentally get oil on the discs, clean them immediately with brake cleaner and don't risk driving. For safety, brake discs should always be dry and uncontaminated, and regular maintenance checks are the most reliable approach.

Can You Make a U-Turn in a Left-Turn Lane?

U-turns are not allowed in left-turn lanes that have a no U-turn sign. According to regulations, motor vehicles are prohibited from making U-turns at locations with no U-turn or no left-turn signs or markings, as well as at railway crossings, crosswalks, bridges, sharp curves, steep slopes, tunnels, or other dangerous road sections. Motor vehicles may make U-turns at locations without no U-turn or no left-turn signs or markings, provided they do not obstruct the normal passage of other vehicles or pedestrians. Permissible U-turn scenarios are as follows: U-turn traffic lights or signs: When an intersection has a U-turn traffic light, a U-turn can be made when the U-turn light is green. If there is a U-turn sign at the intersection or a U-turn marking on the lane, a U-turn is allowed as long as safety for oneself and others is ensured. No U-turn sign but left turns are allowed (no prohibition of U-turn signs): Vehicles can make U-turns at intersections where left turns are permitted and no U-turn prohibition signs or markings are present. It is important to note that vehicles must follow the left-turn lane traffic signal without disrupting the normal flow of other vehicles. If making a U-turn at an intersection with a left-turn waiting area, vehicles may first enter the waiting area when the straight-ahead light is green and then make the U-turn when the left-turn light turns green. U-turns are allowed at dashed lines: U-turns are permitted at both white and yellow dashed lines. For double yellow lines (one solid and one dashed), check whether the side you are on is dashed—if it is, a U-turn is allowed if safe; if it is solid, a U-turn is prohibited. At intersections with double yellow lines (solid and dashed), U-turns can be made on the dashed side, but the vehicle must not cross the stop line ahead.

Can You Press the Accelerator During Hill Start and Stop?

Hill start and stop do not require pressing the accelerator. The hill start and stop exercise is part of the Subject 2 driving test, which does not involve using the accelerator; instead, the clutch is used for starting. The specific steps for hill start and stop are as follows: Before ascending the hill, straighten the direction of the vehicle in the shortest time possible. While ascending the hill, turn on the right turn signal and move towards the right side of the area, aligning the right side of the car parallel to a solid line on the right side of the road. The distance between the side of the car and this solid line must not exceed 30 centimeters, and the car must not cross the solid line. Pay attention to the coordination between the clutch, accelerator pedal, and parking brake lever (handbrake), especially the timing of releasing the parking brake lever (handbrake). After ascending the hill, you will immediately approach a single-plank bridge, so avoid excessive speed. Scoring criteria for hill start and stop: After the vehicle stops, if the front bumper of the car or the front axle of the motorcycle is not aligned with the pole line and exceeds 50 centimeters in either direction, it results in failure. After the vehicle stops, if the front bumper of the car or the front axle of the motorcycle is not aligned with the pole line but does not exceed 50 centimeters in either direction, a 10-point deduction applies.

Is Shell Yanchang's fuel long-lasting?

Shell Yanchang's fuel is long-lasting. Details about Shell Yanchang's fuel are as follows: Reasons why Shell Yanchang's fuel is long-lasting: Because Shell adds gasoline additives to its fuel, which are equivalent to the fuel system cleaners commonly added. These additives can protect the car from the harm of low-quality fuel and are also beneficial to the car's engine, which is why Shell Yanchang's gasoline feels more long-lasting. Introduction to Shell Yanchang Petroleum: Shell Yanchang Petroleum Co., Ltd. was established in December 2008 and is a Sino-foreign joint venture. The gasoline under this brand uses Shell's technology. In China, there are not only two major brands, Sinopec and PetroChina, but also Shell, Shell Yanchang, Gulf Oil, etc. Shell's gasoline is not much different from Sinopec and PetroChina in terms of main components. Compared with the two major oil companies, Shell's fuel sources are more complex, possibly coming from different local refineries, unlike the two major oil companies, which all import crude oil and refine it themselves. Because of the more complex sources, Shell's gasoline generally adds engine cleaners to ensure the actual use effect of the product, while the two major oil companies' gasoline does not.

Does the Gear Shift Mechanism Need Lubricating Oil?

The gear shift mechanism generally does not require lubricating oil. The specific details of the gear shift mechanism are as follows: Generally, the gear lever does not require special lubrication: Regular maintenance is sufficient. It is generally recommended to replace the transmission oil every 40,000 to 60,000 kilometers. If the ball joint at the base of the gear lever is too tight or stuck, a small amount of lubricating grease can be applied to provide lubrication. Manual transmission gear shifting issues can be divided into the following situations: In winter, low temperatures may cause the gear shifting to feel less smooth. In this case, no action is needed, and the issue will resolve once the vehicle warms up. If the vehicle speed and gear position do not match, you can increase the engine speed by blipping the throttle to improve the success rate of gear engagement. If the gear shift mechanism shows signs of aging, it is necessary to perform maintenance.

Can a Cruze be parked in a micro parking space?

A Cruze cannot be parked in a micro parking space. The dimensions of a micro parking space are 4.0 meters in length and 2.2 meters in width, while the Cruze has a body length of 4666mm and a width of 1807mm. If a Cruze is parked in a micro parking space, the car body will exceed the parking space, affecting other vehicles or pedestrians, so it is not allowed. A standard parking space, which is 5.3 meters long and 2.4 meters wide, is suitable for parking a Cruze. Parallel parking tips: Park the car 1.5m away from the parking line; when the driver's seat position aligns with the middle of the next parking space, turn the steering wheel fully to the left and slowly reverse; straighten the car's front wheels immediately when the car is aligned, then continue reversing to park smoothly. Perpendicular parking tips: Make full use of the lane width to angle the car as much as possible, which reduces the angle between the car and the parking space, minimizing the need for steering adjustments during reversing. When the car is angled to the point where the driver's side mirror can see the corner of the left-side parked car, start reversing. While reversing, observe the left mirror to monitor the distance between the left rear wheel and the adjacent car. Once your car's left rear wheel passes the front of the left-side car, shift focus to the right mirror to check the distance between your car's rear and the right-side car. After reversing into the space, pay attention to the rear position to avoid hitting the wall. If the parking lot is too dark to see the rear clearly, rely on the reverse radar alerts or align your car's mirrors with those of the adjacent cars.

What documents are needed to collect the inspection exemption label for someone else?

To collect the inspection exemption label for someone else, you need to bring the vehicle registration certificate, the owner's ID card, and the compulsory traffic insurance policy. The specific details of vehicle inspection exemption are as follows: Vehicle Inspection Exemption: Vehicle inspection exemption means that for vehicles meeting the exemption conditions within six years, the on-site inspection process is waived. Instead, the inspection label must be applied for every two years and affixed to the vehicle as required. Essentially, this exempts the vehicle from on-site inspection. As long as the vehicle meets the national policy conditions, there is no need for on-site inspection, and the inspection label can be directly applied for from the traffic management department. Types of vehicles eligible for inspection exemption: Non-commercial cars and other small and mini vehicles, as well as vans (excluding 7-seater and above vehicles) within six years.
