What Causes the Brake Caliper to Make Abnormal Noises?

Abnormal noises from the brake caliper may be caused by loosening or rusting of the guide pins. Replacing and lubricating them with grease can resolve the issue. It could also be the sound of the brake pads hitting the caliper. Additionally, if there are foreign objects between the caliper and the brake disc, abnormal noises may occur. It is best to diagnose the specific cause at a repair shop. Below is an extended introduction: 1. Brake Caliper Concept: The brake system consists of a master cylinder and brake calipers. Simply put, the master cylinder stores brake fluid and has inlet and outlet ports. When the brake pedal is pressed, the brake fluid flows from the master cylinder through the pipelines to the brake calipers. When the calipers are pressurized, they push the brake pads to frictionally engage the brake drum, thereby achieving braking. 2. Symptoms of a Faulty Brake Caliper: 1) Oil leakage at the connection between the caliper and the oil pipe, and the brake pedal feels soft when pressed; 2) After pressing the brake pedal, the steering wheel noticeably pulls to one side, which is likely caused by uneven brake pad wear or a faulty caliper; 3) After pressing the brake pedal, the pedal does not rise and lacks resistance, commonly known as the brake not returning to position.

Is Driving at 100 in a 90 Speed Limit Considered Speeding?

Driving at 100 in a 90 speed limit is considered speeding. Here are the hazards of speeding: 1. Vehicle steering becomes unstable: Speeding increases the airflow speed difference between the top and bottom of the vehicle body. This differential causes the vehicle to generate upward lift, reducing stability during driving, which is a significant factor in unstable steering. 2. Increased driving risks: Higher speeds mean greater inertia to maintain straight-line movement, leading to poorer directional control and significantly increased risks. In the event of sudden incidents ahead, it becomes difficult to control the vehicle within a short time, potentially resulting in unimaginable consequences.

What Causes the Rattling Noise When the Car Window is Fully Closed on Bumpy Roads?

Window rattling noise may be caused by abnormal width of the window glass guide channel. This leads to friction between the glass and other parts when driving on bumpy roads, resulting in the noise. Below is an introduction about car windows: 1. Introduction: Car windows are openings in the four walls of the vehicle compartment, designed to block wind and rain without obstructing vision. They are generally made of glass materials, which have evolved significantly over time. 2. Classification: Safety glass - including laminated glass, tempered glass, and zone-tempered glass, among others, has greatly improved the performance of automotive glass. 3. Composition: Ordinary automotive glass is made of silica glass, with silicon dioxide content exceeding 70%, and the rest composed of sodium oxide, calcium oxide, magnesium, etc.

Should You Downshift to First Gear When Pulling Over?

During the Road Test (Subject Three), it is necessary to downshift to first gear when pulling over. The deceleration process must involve sequential downshifting until reaching first gear before coming to a complete stop. Below are relevant details: 1. Subject Three: Subject Three, which includes the road driving skills test and the safety-conscious driving knowledge test, constitutes a part of the motor vehicle driver's license examination. It is the abbreviated term for the road driving skills and safety-conscious driving knowledge test in motor vehicle driver examinations. The content of the road driving skills test varies depending on the type of vehicle license being pursued. 2. Pulling Over: Pulling over is a clearly defined assessment item in the road test, requiring the examinee to maneuver the vehicle to a stop by the roadside.

How often should a vehicle be inspected?

Here are the specific regulations for vehicle annual inspection intervals: 1. Passenger transport vehicles: Inspect once per year within the first 5 years; inspect every 6 months after exceeding 5 years. 2. Trucks and large/medium non-passenger transport vehicles: Inspect once per year within the first 10 years; inspect every 6 months after exceeding 10 years. 3. Small and mini non-passenger transport vehicles: Inspect once every 2 years within the first 6 years; inspect once per year after exceeding 6 years; inspect every 6 months after exceeding 15 years. 4. Inspection exemption policy: Family vehicles with 6 seats or fewer enjoy a 6-year inspection exemption. The prerequisite for this 6-year exemption is that no major traffic accidents occur during this period. If an accident occurs, an on-site inspection is mandatory. Vehicles with 7 seats or more do not qualify for the 6-year exemption policy and still require inspection every 2 years during the first 6 years.
