It is recommended to replace the entire assembly if the clutch slave cylinder is leaking oil. Below are the relevant details: 1. Explanation: Leakage in the clutch slave cylinder is caused by wear and tear of the piston, rubber seals, and cups inside the cylinder, which fail to contain the clutch fluid. Since replacement parts for the clutch slave cylinder are not readily available, repairing or replacing individual components like seals is impractical, making a full assembly replacement the only viable option. 2. Working Principle: When the clutch pedal is depressed, hydraulic fluid from the clutch master cylinder is delivered to the slave cylinder via high-pressure lines. The pressure of the hydraulic fluid acts on the plunger cup inside the slave cylinder, pushing the plunger rod forward. The plunger rod then moves the release lever forward, which in turn presses the release bearing against the release lever, thereby disengaging the clutch and cutting off power transmission between the engine and the drivetrain.

Is driving at 132 km/h considered speeding when the speed limit is 120 km/h?

Driving at 132 km/h is considered speeding when the speed limit is 120 km/h. Penalties for speeding: According to relevant regulations, motor vehicles violating speed limits on roads will face corresponding penalties. Exceeding the limit by less than 10% results in a warning, 20-50% leads to 6 penalty points, and exceeding by 50% or more results in 12 penalty points. Legal provisions regarding speeding: Article 42 of the Road Traffic Safety Law states that motor vehicles driving on roads must not exceed the maximum speed indicated by speed limit signs. On road sections without speed limit signs, drivers should maintain safe speeds. When driving at night, on dangerous road sections, or under adverse weather conditions such as sandstorms, hail, rain, snow, fog, or icy roads, drivers should reduce their speed.

Why is the car dashboard not displaying?

Car dashboard not displaying is due to poor contact at the battery terminals. Below are the specific introductions to dashboard indicator lights: 1. Indicator Lights: Such as turn signal lights, parking lights, etc., their function is to indicate the status of various vehicle functions. 2. Warning Lights: Warning lights serve an alert function, such as fuel indicator lights, door status indicator lights, seatbelt indicator lights, etc. Generally, warning lights turn off after the driver performs the corresponding action, for example, the seatbelt indicator light turns off once the driver fastens the seatbelt. 3. Fault Indicator Lights: Such as generator fault indicator lights, ABS fault indicator lights, transmission fault indicator lights, etc. Normally, these fault indicator lights rarely light up, or they may light up briefly when starting the engine and then turn off. If a fault indicator light stays on continuously accompanied by a warning sound, it indicates that the vehicle has a malfunction or abnormality.

What Are the Symptoms of a Damaged Car Clutch?

The symptoms of a damaged car clutch include: 1. Decreased vehicle power; 2. Abnormal noises when pressing or releasing the clutch pedal; 3. Uneven sensation when releasing the clutch during startup. The clutch is located within the flywheel housing between the engine and the transmission, with the clutch assembly secured to the rear plane of the flywheel by screws. The output shaft of the clutch serves as the input shaft of the transmission. Precautions for clutch usage are: 1. The clutch must be thoroughly cleaned before installation to remove anti-rust grease and debris; 2. The clutch can be installed coaxially or on separate shafts, with axial fixation required; 3. For wet electromagnetic clutches, lubricating oil must be added between the friction plates during operation; 4. The power supply and control circuits should use a 24V DC power source for the clutch; 5. During the installation of jaw-type electromagnetic clutches, a certain gap must be maintained between the end face teeth to prevent grinding when idling.

What are the actual ground clearances of the XR-V and Vezel?

XR-V has a minimum ground clearance of 140mm. Vezel has a ground clearance of 170mm. The minimum ground clearance of XR-V and Vezel refers to the distance between the lowest point (excluding wheels) and the supporting plane, which characterizes the vehicle's ability to pass over obstacles like rocks and tree stumps without collision. Generally, the higher the ground clearance of XR-V and Vezel, the better the passability. However, if the ground clearance is too high, the stability at high speeds will decrease. As a new masterpiece in the subcompact SUV segment by Dongfeng Honda, the Honda XR-V inherits the excellent quality and manufacturing craftsmanship of the CR-V, featuring a stylish exterior and high-quality interior. The XR-V measures 4272mm in length, 1772mm in width, 1605mm in height, with a wheelbase of 2610mm. The Honda Vezel is an SUV developed from the chassis of the all-new Fit. At the 2014 Beijing Auto Show, GAC Honda officially launched its new compact SUV—Vezel. Positioned as a compact SUV, the Vezel measures 4328mm in length, 1772mm in width, 1605mm in height, with a wheelbase of 2610mm. Generally, the ground clearance of sedans ranges between 110mm and 150mm, while SUVs have a ground clearance between 200mm and 250mm. However, the ground clearance of XR-V and Vezel is not static; it also depends on the load condition. Therefore, changes in ground clearance should be considered based on the load variations of XR-V and Vezel. When selecting a vehicle, ground clearance can be one of the reference factors. The choice should depend on the vehicle's intended use and driving conditions. For urban areas with good road surfaces, vehicles with lower ground clearance can enhance stability and comfort. For long-distance travel or driving in areas with poor road conditions, vehicles with higher ground clearance are preferable to avoid chassis scraping or damage, considering the off-road performance.

Reasons Why Car Lights Don't Work After Rain

The reason why car lights don't work after rain is that the wavelength of the light is long, and in rainy or foggy conditions, the light cannot refract properly, resulting in reduced penetration. Additional information: Methods to clean car lights: 1. Clean stains with water. Simply wipe the stains off the lamp cover with clean water, then use soapy water to clean the yellowed areas on the headlights. This will prevent the headlights from yellowing for a long time. 2. Use a polishing machine for restoration. This can make the lamp cover look brighter. Dip a clean sponge in some polishing compound and wipe the headlights. The effect will be noticeable after wiping, and it also acts as a protective layer for the lamp cover. 3. Use toothpaste for cleaning. Apply a small amount of toothpaste to the lamp cover and wipe in a circular motion. If there are obvious scratches on the lamp cover, add more toothpaste and gently wipe. After wiping, the headlights will become more transparent. Usually, wiping for about five to six minutes is sufficient, then rinse with clean water and dry with a soft cloth.
