What Causes the Rumbling Sound When Braking at High Speed?

High-speed braking with a rumbling sound is typically caused by an issue with the brake caliper. Below are specific explanations regarding abnormal brake noises: 1. Squealing Noise: First, check if the brake pads are nearly worn out. For new brake pads, inspect whether the brake disc has grooves, as localized friction can cause abnormal noises. If the brake disc is fine, consider whether the brake pads are too hard, if the anti-noise shims are incorrectly installed, or if there are foreign objects trapped between the brake disc and pads. 2. Hissing Noise: A hissing noise can indicate various issues, potentially involving the caliper, brake disc, or brake pads. 3. Continuous Noise: If the noise persists, check for dragging brakes. Poor reset of the brake caliper can cause prolonged friction between the brake disc and pads, leading to abnormal noises under certain conditions.

How to Adjust the Steering Wheel on a Mercedes-Benz?

Ensure that the seat parameters have been fully adjusted to a reasonable position. Only after the seat is properly adjusted can you proceed to the steering wheel adjustment step. Manually, there is a lever right below the steering column. Pull it downward once. On the left side of the steering column, there are three control levers. Adjust by pulling the shortest lever up, down, forward, or backward.

Why is the car steering wheel shaking?

Car steering wheel shaking may be caused by tire deformation or issues with the vehicle's drivetrain. It could also be due to wear in the tie rod ball joint, detachment of the rubber sleeve at the joint, or irregular tire wear. If the steering wheel shakes when driving at speeds between 80 to 90 kilometers per hour but returns to normal above 90 km/h, it is likely due to tire deformation or drivetrain problems. If the steering wheel shakes on flat or uneven roads, it may indicate a loose tie rod ball joint, detached rubber sleeve at the joint, or irregular tire wear due to wear and tear. In such cases, immediate repair is necessary.

Can I still drive on the highway without an ETC?

You can still drive on the highway without an ETC by obtaining a toll card at the entrance toll station and stopping to pay the toll at the exit toll station. ETC is a fully automatic electronic toll collection system and one of the service functions of intelligent transportation systems, particularly suitable for use on highways or in busy bridge and tunnel environments. Currently, highway toll stations have dedicated ETC lanes. Vehicle owners only need to install a sensor card on the windshield and preload funds. When passing through the toll station, there is no need for manual payment or stopping—the highway toll will be automatically deducted from the card, enabling automatic toll collection. This system processes each vehicle in less than two seconds, with a lane capacity 5 to 10 times that of manual toll lanes.

What causes shaking and vibration when stepping on the car brakes?

Reasons for shaking and vibration when stepping on the car brakes: 1. Problems with the brake pads and brake discs; 2. Severe unilateral wear of the brake disc; 3. Poor return of the brake pump. Compared to brake pads, brake discs wear out more slowly, and repair shops generally recommend replacing brake pads and brake fluid. After a certain period of use, brake discs may wear out, leading to uneven surfaces or thickness that does not meet standards, which can severely affect braking performance over time. Braking, also known as deceleration, refers to the action of stopping or reducing the speed of running locomotives, vehicles, and other transportation tools or machinery. The general principle of braking involves fixing a wheel or disc on the high-speed shaft of the machine and installing corresponding brake shoes, bands, or discs on the machine base to generate braking torque under external force.

Where is the spare tire of the Encore placed?

The spare tire of the Encore is placed under the trunk panel. To install it, place the spare tire under the trunk panel and secure it with screws. Here are some important notes regarding the spare tire: 1. Regularly inspect the spare tire. The inspection mainly involves checking the tire pressure and looking for any wear or cracks. Replace the tire as soon as possible if the tread wears down to the wear indicator line. 2. Avoid placing oil products near the tire. The main component of tires is rubber, which is highly susceptible to damage from oil products. If the tire comes into contact with oil, it may swell and corrode, significantly reducing its lifespan. 3. Replace the spare tire periodically. Since tires are made of rubber, they can age over time. The typical aging period for tires is about 4 years, so the spare tire should be replaced after this period.
