My Mercedes-Benz GLC started making screeching brake noises after just over 20,000 kilometers, especially noticeable during slow-speed stops. The dealership inspection revealed that the OEM brake pads have high metal content, causing friction noise with the rotors. The technician reduced the noise significantly by smoothing the edges of the brake pads and applying lubricant to the caliper slide pins. I'd suggest you first check your brake pad thickness - replacement is recommended if it's below 3mm. If you notice grooves on the rotors, those might be hard spots worn by the pads, requiring resurfacing. Don't ignore it, as abnormal noises indicate unusual wear in the braking system.

Can the Rear Seats of the 7th Generation Elantra Be Folded Down?

The rear seats of the high-end version of the 7th Generation Elantra can be folded down. Here is some relevant information about the Elantra: 1. Introduction: The Elantra is a typical Korean car. As the best-selling overseas model of Hyundai, it has gone through six generations. The Beijing Hyundai Elantra is based on its sixth-generation model, with slight improvements made to suit Chinese road conditions and climate. It is well-received for its rich configurations and relatively high cost performance. 2. Body: The overall body of the Elantra appears gentle and elegant, but the redesigned front face gives it an aggressive look. Two thick ridges on the engine hood extend forward to a small but prominent grille, creating a strong sense of forward motion. The redesigned wedge-shaped headlights are more sporty and aggressive than the peanut-shaped ones on the Sonata, even featuring a modified effect known as 'smoked headlights' in the tuning community.

Why does the oil life indicator not change after an oil change?

After changing the engine oil, the reason the oil life indicator does not change is because the oil life reset operation was not performed. Here are some details about engine oil: 1. Function: Engine oil, also known as engine lubricant (English name: Engine-oil), has a density of approximately 0.91×10³ (kg/m³). It serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption for the engine. It is often referred to as the "blood" of a car. 2. Composition: Engine oil consists of two main parts: base oil and additives. The base oil is the primary component of the lubricant, determining its basic properties, while the additives compensate for and improve any shortcomings in the base oil's performance, giving it new characteristics. Additives are an essential part of engine oil.

What Causes the Handbrake to Lock Up After Rain?

Handbrake lock-up after rain occurs when the brake pads and drums rust and fuse together after prolonged parking with the handbrake engaged following water exposure. Below are detailed explanations of other causes for brake lock-up: 1. Brake Caliper Failing to Retract: Even without pressing the brake pedal, noticeable resistance is felt while driving, and in severe cases, abnormal noises or wheel lock-up may occur. This is often due to internal corrosion of the brake caliper from not changing brake fluid for an extended period. It can be repaired by sanding and applying grease; if the caliper itself is faulty, replacement is necessary. 2. Master Cylinder Cup Jamming: This typically happens when water or other contaminants enter the brake system, or when switching to a different brand of brake fluid without cleaning the system first, causing the master cylinder cup to swell and resulting in lock-up.

How to Adjust the Timing of a Jetta Car?

The steps to adjust the timing of a Jetta car are as follows: 1. First, use the timing wheel axle clamp of the Jetta King to secure the timing wheel axle to prevent movement during adjustment, which could lead to alignment failure. 2. Then, slightly loosen the screws on the timing wheel to facilitate subsequent chain alignment. 3. Next, locate the colored chain on the timing wheel axle, which serves as a marker for adjustment. 4. Finally, release the clamp securing the wheel axle to complete the alignment. Additional information about car timing is as follows: 1. The engine's valve timing mechanism controls the timing and duration of the engine's intake and exhaust. 2. Its function is to open and close the intake and exhaust valves of each cylinder in sequence according to the engine's operating order, allowing fresh air to enter the cylinders and expelling the combustion exhaust gases.
