Front and rear brake pads do not need to be replaced together as they have different replacement cycles. Compared to front brake pads, rear brake pads have a longer service life. Under normal driving conditions, front brake pads typically need replacement every 30,000-50,000 kilometers, while rear brake pads can last about 60,000-100,000 kilometers before requiring replacement. Introduction to brake pads: 1. Automotive brake pads, also known as brake linings, refer to the friction materials fixed on the brake drum or brake disc that rotates with the wheel. The friction lining and friction block within them withstand external pressure to generate friction, thereby slowing down the vehicle. 2. Automotive brake pads are generally composed of a steel plate, adhesive heat insulation layer, and friction block.

I'm a seasoned auto mechanic who changes brake pads every day. Let me tell you honestly, there's really no need to replace front and rear pads together. The front brake pads handle most of the braking force and wear out at least twice as fast as the rear ones. For regular family cars, front pads typically need replacement around 40,000 km, while rear pads can last at least 70,000 km. Plus, most modern cars have brake wear sensors - it's perfectly fine to replace them when the warning light comes on. During every maintenance check, I always inspect the thickness for customers. I recommend replacement when front pads go below 3mm, while rear pads can still keep working. Replacing both sets simultaneously is just throwing money away - why replace rear pads that still have 20,000 km left? Of course, if you're the type who loves driving fast and brakes aggressively, then the wear will be faster.

What are the steps for changing the oil in an automatic transmission using a machine?

Here are the steps for changing the oil in an automatic transmission: 1. Connect the exchange machine: Open the hood, place fender pads, lift the vehicle, perform a simple inspection of the vehicle's chassis, locate and confirm the position of the transmission cooling oil pipes, select the appropriate connecting adapters, and connect the two hoses of the exchange machine to the transmission's inlet and return oil pipes respectively. 2. Check the old oil: Start the vehicle, connect the smart exchange machine to the battery, turn on the smart exchange machine, and observe the cleanliness of the old oil from the old oil display tube. If metal particles, sludge, friction plate fragments, or other impurities are found in the old oil, it may indicate internal wear in the transmission, requiring further repairs and making it unsuitable for an oil change at this time. 3. Replace the filter: Turn off the engine, lift the vehicle, open the drain plug, and drain the old oil. Use a measurable container to collect the old oil, remove the oil pan, and pour the oil inside the oil pan into the old oil container. Replace the oil pan gasket and, if possible, also replace the filter. Note that the location of the filter may vary significantly between different vehicles. 4. Circulation cleaning: Add new oil to the exchange machine, activate the "fill new oil" function of the exchange machine, set the filling amount to match the drained old oil quantity, and start the vehicle. Activate the "circulation cleaning" function of the exchange machine. The driver should operate the gearshift mechanism to perform circulation cleaning for each gear, with each gear's cleaning time controlled within 5-10 seconds, and the total circulation time between 5-8 minutes. 5. Equal exchange: After circulation, stop the engine, add new oil to the exchange machine again, and select the "equal oil exchange" function. Upon completion, observe whether the colors of the new and old oil in the exchange machine match. If they match, the operation is complete. If not, continue adding new oil until the colors of the new and old oil match. Check if the oil level is sufficient. For transmissions with a dipstick, check the dipstick's scale position. For those without a dipstick, lift the vehicle and open the inspection bolt. Excess oil will overflow from the inspection bolt hole. If no overflow occurs, add new oil via the smart exchange machine based on the actual situation until oil overflows.

How to fold down the rear seats of the Yaris L?

Before folding down the rear seats, move the front seats forward to ensure there is enough space for the rear seats to be folded. Close the center armrest in the rear seats to avoid friction, and retract the seatbelt buckle of the middle rear seat. It is best to have the headrest in the lowest position. There is a thin strap on the side of the rear seat—pulling it allows you to adjust the backrest angle forward or backward. Fold down the rear seats.

How to Remove the Dashboard of a Mercedes-Benz GLK300?

Use a lock disassembly tool to turn the lock to the left until it comes apart. If professional disassembly tools are difficult to purchase, you can borrow them from an auto shop. Use a pry bar to remove the small panel on the far right (near the right door). Use a hex ball-head screwdriver to unscrew the internal screws. Raise the steering wheel to its highest position, use a pry bar to open the gaps on both sides of the steering wheel lock, remove the air vents, and be careful to disconnect the warning light wiring. Finally, use a pry bar to slowly pry open the screen.
