Porsche 911 Turbo Porsche, the German sports car manufacturer, announced that the company will recall the Porsche 911 Turbo, Turbo S, 911 GT3, GT3 RS and GT2 RS models from 2010 to 2011 in the US market in order to loosen the axles of these vehicles. Replace the screws.
In a document submitted to the National Highway Traffic Safety Administration, Porsche stated that the recall involved a total of 1,702 vehicles, with production dates from May 18, 2009 to September 17, 2010.
Porsche stated that as time goes by, the hub of the vehicle may wear out prematurely and the tires cannot be reliably prevented from loosening, which will increase the risk of a crash.
Porsche has received and confirmed four reports of accidents from Europe related to the above issues. In addition, an accident report from the United States has not yet been confirmed. In this regard, Porsche said that no one was injured in the accident.
Friction discs are components composed of chips and friction linings or layers of friction material, which are widely used in the fields of mechanical engineering, mechanical parts and clutches.
Brake pads, also called brake pads, are actually brake pads. In the braking system of a car, brake pads are very important safety parts and play a key role.Brake pads determine the quality of the braking effect and are closely related to the safety of the car, so the daily maintenance of the brake pads is particularly important.
The friction plate has a suitable friction coefficient: The friction coefficient is the basic parameter of the friction material, which determines the basic braking torque of the brake pad. The national standard strictly requires the manufacturer to indicate the friction coefficient on the package. The friction coefficient must be appropriate, too high will cause During the braking process, the wheels are locked, the direction is out of control and the disc is burned. If it is too low, the braking distance will be too long.2 Friction pads have reliable safety: Brake pads will generate instantaneous high temperature during braking, especially when driving at high speed or emergency braking. Under high temperature conditions, the friction coefficient of friction pads will decrease, which is called thermal recession. The level of thermal decay determines the safety of the high temperature state and emergency braking.
