Which is the Brake and Which is the Accelerator in a Motor Vehicle?
1 Answers
In a manual transmission vehicle, there are three pedals arranged from left to right: the first is the clutch, the second is the brake, and the third is the accelerator. The left foot controls the clutch, while the right foot controls the brake and accelerator. An automatic transmission vehicle has only two pedals, arranged from left to right: the brake pedal and the accelerator pedal, both controlled solely by the right foot. The brake system consists of brake calipers and brake pads installed on the wheel hubs, with a master brake cylinder installed in the driver's compartment. Brake cylinders can be hydraulic, pneumatic, or lever-type, and operating the master brake cylinder applies braking force to the moving vehicle. The accelerator controls the fuel injection volume of the engine. When the accelerator is pressed down, a larger fuel injection increases the engine speed, thereby making the vehicle move faster.
