Brake Class: The Function Unit

To better understand brakes, you might find a quick overview of how brakes work useful. Brakes work because of friction and hydraulic forces. Once you put your foot on the brake pedal, in both scenarios level and piston move to apply force to the master cylinder where brake fluid is stored. The pressure increases until the fluid goes through brake lines to the cylinder at each wheel. How great is that? A small amount of force multiplies into enough to stop your vehicle. That’s the value of hydraulics. The fluid force moves brake parts into place so that they’re in the right place to create friction. Newer cars typically have disc brakes (at least on the front wheels). Brake calipers holding metal brake pads are moved by the hydraulic pressure such that there is contact between the pads and large metal discs (rotors). Older models and the back wheels of some up-to-date autos have drum brakes. The fluid pressure forces brake shoes against a drum turning inside each wheel. In both scenarios, the metal against metal generates enough friction to slow and stop your car.

Perhaps you’re wondering how you’ll know if your brakes need attention. Observe for some of the common signs. One of the most obvious indicators is an illuminated brake light on your dashboard. This could mean you left the parking brake on, or it could warn of trouble. Noises such as grinding, screeching, and squealing should also prompt you to have your brakes checked. Watch for a “soft” or spongy brake pedal. It shouldn’t go all the way to the floor when you press it. A burning smell sometimes points to a stuck brake caliper or that you’re driving with the emergency brake engaged. Finally, uneven or warped rotors may present themselves with vibration, wobbling, or scraping when you brake. If you’re noticing any of these frequent signs of trouble, don’t delay bringing your automobile to Full Service Master Car Care for brake repair.
