Xu purchased an agricultural three-wheeled transport vehicle to transport vegetables to the market for sale. One morning, while Xu was carrying a cart full of vegetables to the market, something went wrong with his tricycle and an accident occurred, killing one and injuring one.

was entrusted by the public security agency to conduct identification and analysis of the causes of the agricultural tricycle accident involved.
identification and analysis results: The
identification and analysis expert team inspected the accident car and found brake fluid in the brake fluid tank. In addition, the fixing bolt of the left rear wheel cylinder was missing, and the spring washer failed to tighten, causing the rear fixing bolt of the wheel cylinder to loosen and fall off. The loosening of the front fixing bolts caused the rear side of the wheel cylinder to deflect outwards, causing the acceptance point between the push rod and the piston to change, causing the piston to break, eventually causing the brake fluid to leak and losing braking power, resulting in the vehicle's braking failure, and then causing an accident.
