What are the common reasons for a sedan's rear wheel not turning?

The common reasons for a sedan's rear wheel not turning are usually due to a seized rear wheel bearing or the right rear brake pad not retracting properly, which can also cause this phenomenon. Below is relevant information about automotive brakes: 1. Introduction to Brakes: Braking, also known as deceleration, refers to the action of stopping or reducing the speed of moving locomotives, vehicles, other transport tools, or machinery. The general principle of braking involves fixing a wheel or disc on the machine's high-speed shaft and installing corresponding brake shoes, bands, or discs on the machine base to generate braking torque under external force. The braking device, also known as a decelerator, is a mechanical device that can slow down the vehicle's speed. 2. Classification of Brakes: Drum brakes (advantages and disadvantages), disc brakes, etc.
There could be several common reasons why the rear wheel isn't turning. The most frequent issue is a stuck braking system, such as a seized brake caliper or locked brake disc, preventing the tire from rotating. Another possibility is a drivetrain malfunction, like a broken half-shaft, differential problem, or damaged drive shaft in rear-wheel-drive vehicles. Additionally, a damaged bearing is a common factor, which can cause the tire to jam or produce noise. Suspension system issues, such as deformed control arms, may also affect rotation. I recommend starting with simple checks: shake the tire to see if it's loose and listen for any unusual noises. If that doesn't help, it's best to take it to a professional repair shop promptly to avoid potential hazards on the road. A locked tire is not only dangerous but can also damage other components like the tire tread or suspension. Regular maintenance, including brake and drivetrain inspections, can effectively prevent such issues, saving you from costly and time-consuming major repairs. Never ignore minor noises, as delaying repairs can lead to higher costs later.
