Power Unit In Brakes

If you start cutting taxes on the middle class but start increasing on the rich, it is likely to result in an economic burnout, Similarly, with one foot on the accelerator and the other on the brake is likely to get you nowhere, but certainly will burn out vital parts of your car. Its a fact. Today let's understand the braking system in our cars. In short, it is just a system of hydraulics where the force is multiplied and forces the brake fluid through the brake lines to the brakes. The first stage is the vacuum booster where the force applied by the driver on the pedal gets multiplied by reducing the pressure inside the vacuum booster. The second stage is the master cylinder. You will find 2 chambers which consists the primary and secondary pistons. These pistons then compress the fluid and is sent through the brake lines to the brake calipers which are situated at the brakes themselves. The third stage is the brake calipers. They are one of the most important automobile brake parts as they are essential for the car's ability to stop. The caliper is fitted over the rotor. They are only used in disc brakes as in drum brakes it has the wheel cylinder assembly. The hydraulic pressure from the master cylinder acts on the pistons at the calipers. Due to this the pistons move in the forward direction and force the brake pads against the rotor. The brake pads should have high friction surfaces. Older cars and trucks used drum brakes. But it resulted in brake fade as the gases and heat was built up in the drum rather than external in case of disc brakes. However, you will find some old cars with drum brakes at the rear end.
