How do the Disc Brakes Work?

The brakes should be able to respond instantly. When the driver puts pressure on the pedal, the piston inside the brake master cylinder will pressurize the hydraulic fluid in the brake lines, which shifts the piston and pushes the pads into the rotor. The harder the driver will push on the pedal, the greater the pressure inside the brake lines, and harder the rotor will be squeezed by the pads. The distance the pads move is quite minimal, only a few millimeters. And they should be able to retract back into the calipers as quickly as the driver lets off the pedal.

Wear and tear on disc brakes

Even in the usual driving cases, the disc brake systems deal with the major pressure and heat and over time many components will require some replacement. The brake pads need to be replaced most frequently. When that takes place, which also depends on your specific driving habits and the materials the pads are composed of, but it is also ranging between 25,000 and 70,000 miles. The brake rotors tend to last between 50,000 and 70,000 miles and sometimes even more. But it can also be damaged if they tend to overheat or if the brake pads couldn’t be replaced on time. Brake fluid is deemed the cornerstone of the entire brake system. So inspect it in every 24,000 to 36,000 miles or in an instant if you are suspecting a leak. Pistons and calipers should be able to last a lifetime of the vehicle, unless and until there is any kind of mechanical issue, they are prone to damage by debris or in a crash, or if they seize because of the inactivity.

Symptoms of Problems with Disc Brakes

  1. Squealing noise

As the brake pad is wearing off, the metal wear indicator inside the pad touches the rotor emitting a high pitched squealing noise. Replacing the brake pads usually fixes the noise, but it is also caused by road debris stuck in the caliper.

  1. Shaking or pulsating pedal

If the brake pedal is pulsating or shaking when you apply pressure on it, probably your rotors are warped. Brake rotors are meant to be flat and a warp is caused by overusing or overheating. Rotors can be resurfaced to make them smooth again, but replacing it is a moderately priced and a safer option.
