What Causes the Rear Wheels to Stop Turning After Starting the Car?

[LaAlan]

Two possible reasons: either the brake pads and discs are stuck with foreign objects, causing dragging brakes accompanied by abnormal friction noises, or the brake caliper lacks oil or is damaged, preventing separation and resulting in dragging brakes. Below are detailed explanations about car tires: Types of Tires: Pneumatic tires are categorized into tube tires and tubeless tires based on their structure. Passenger cars commonly use tubeless tires. Depending on the arrangement of the internal cord layers and buffer layers, tires can also be divided into radial tires and bias-ply tires. Radial tires are widely used in vehicles. The sidewalls of tires are labeled accordingly. Functions of Tires: Tires directly contact the road surface and, together with the car's suspension system, help absorb shocks during driving, ensuring good ride comfort and smoothness. They also maintain strong adhesion between the wheels and the road, improving traction, braking, and off-road capability. Additionally, tires bear the weight of the car.
