Hello readers! Thanks for joining us today. Let us take a look at the parts in the spotlight today.

Part No 18015427 is a wheel brake cylinder or caliper manufactured by General Motors. Brake calipers are one of the most significant automobile brake parts as they are vital to the car’s ability to stop when required. They are present in nearly all vehicles that run on a disk braking mechanism. Today nearly all cars and trucks have disk brakes in the front wheels and occasionally the rear wheels too. When a car is in the motion the wheels are attached to metal plates or rotors that roll along with the wheels. The brake caliper comes into play when the car needs to be slowed down and they do this by creating an enormous amount of friction between the rubber wheels and the metal disks.

Brake calipers such as part number 18015427 comprise a metal plate bonded with a high friction material called a brake pad. This particular wheel brake cylinder consists of an outboard brake pad on the outside of the disks near the road and an inboard brake pad on the inside of the disks near the wheels. Hence the brake calipers fit on to the wheel like a clamp. When the driver steps on the brake, brake fluid from the master cylinder gushes out exerting hydraulic pressure on the brake pads. Since these brake pads have high-friction surfaces they slow the rotor, which in turn brings the wheels to a halt.

Part No 18015603 is a rocker switch manufactured by Marquardt. The component belongs to the company’s 1800 series of switches.

The name rocker switch is due to the fact that the switch ‘rocks’ into an on-off position when pressed. Thus you will observe one portion of the switch depressed while the other part is raised at all times. Rocker switches are extremely common and are commonly seen in surge protectors, computer power supplies and display monitors.
