What is a Brake Rotor?
A brake rotor is popularly known as a brake disc. It is a shape or surface that is round and flat in appearance. As it is shown in the image below that fine flat surface is the disc. This rotor or disc spins with the wheel as the car moves forward and backward.
The function of a Disc
Brake rotors are a necessary component in the braking system that stops the vehicle. Brake rotors are what the vehicle’s brake pads clamp down on to stop the wheels from spinning. Brake rotors are just as important to stop the vehicle as the brake pads are.
In a disc brake system, most vehicles have disc brakes only on the front wheels, though newer vehicles may have disc brakes on all four wheels. A disc brake is a type of brake that uses calipers. As it is shown above, the caliper is the one attached to the side of the disc. It is in the caliper that the brake pads are attached and the disc will be in between the pads. The caliper will squeeze the pair of pads against a disc or “rotor” to create friction.
How is it done? With disc brakes, the fluid from the master cylinder forces into a caliper where it presses against a piston. The piston squeezes two brake pads on a disc rotor attached to the wheel. This forces the wheel to slow down and stop.
The Brake Pads
These pads are installed by pairs in the caliper. In between the pads is the brake disc. When the inner pad is pushed by the piston both the pads will squeeze the disc to halt the car.

When to Replace Brake Pads?
It is not easy to determine when a brake pad is to be replaced. While other cars have exposed brake pads so you can easily see it if it’s replaceable or not, others need to be intentionally inspected by a technician. One way of calculating and determining when to replace a brake pad is the number of years you used your car and that depends on your way of driving.
Are you fond of driving fast that you have to use the brake every time and then?
Or, the road condition to where you are driving needs the braking every time you travel? Let’s say you drive uphill to downhill every day and vice versa. Or, you are driving in an offroad that sometimes it’s muddy?
These will determine how long your car’s brake pads can last. I know good brake pads can last up to five years or more.
To ensure your brake pads are in the expected condition you need to check it every two years. There’s nothing wrong if you are always on the safe side than to be regretful by being lenient about it.
