how cruise control systems work

The cruise control system actually has a lot of functions other than controlling the speed of your car. For instance, the cruise control pictured below can accelerate or decelerate the car by 1 mph with the tap of a button. Hit the button five times to go 5 mph faster. There are also several important safety features -- the cruise control will disengage as soon as you hit the brake pedal, and it won't engage at speeds less than 25 mph (40 kph).

The system pictured below has five buttons: On, Off, Set/Accel, Resume and Coast. It also has a sixth control -- the brake pedal, and if your car has a manual transmission the clutch pedal is also hooked up to the cruise control.

how does a push button car start

For the vast majority of people, cranking your car involves getting the key out, sliding it into the ignition, and turning it to the “run” position. However, if you have a push-button start system, then you don’t have to do that. You just get inside and push the button labeled start/stop, and the engine roars to life. Simple and easy, right? Actually, these are pretty complicated systems.

how disc brakes work

The single-piston floating-caliper disc brake is self-centering and self-adjusting. The caliper is able to slide from side to side so it will move to the center each time the brakes are applied. Also, since there is no spring to pull the pads away from the disc, the pads always stay in light contact with the rotor (the rubber piston seal and any wobble in the rotor may actually pull the pads a small distance away from the rotor). This is important because the pistons in the brakes are much larger in diameter than the ones in the master cylinder. If the brake pistons retracted into their cylinders, it might take several applications of the brake pedal to pump enough fluid into the brake cylinder to engage the brake pads.

wha tdoes that button do

There are plenty of buttons in your car. Do you know what each one is?

how break rotors work

Most drivers know that they need to perform a little routine maintenance to keep their vehicle in good, working condition. That may involve regularly changing the engine oil, maintaining proper tire pressure and occasionally monitoring the levels of each of the vehicle's vital fluids. Some components and systems require a little more maintenance and others require a little less. In terms of your vehicle's braking system, if you regularly check the fluid and change your brake pads, you have nothing to worry about, right?
