Got a worn-out brake disc? You should get a replacement soon. After all, it is your safety that could be at stake if you continue using your old brake disc. Make sure, though, that the new brake disc that you get will be just right for your car.
What is the brake disc for?
The brake disc, also called the rotor, is basically just a flat, round piece of metal that is attached to your car's wheel. It is the part of your braking mechanism that actually does the work of slowing down and stopping your vehicle.
A typical disc brake system consists of a rotor and a caliper with brake pads on two ends. When you step on your brake pedal, the caliper is activated, making the brake pads squeeze the brake disc. The friction generated between the pads and the disc slows down and eventually stops your car.
What type of brake disc to get?
Brake discs differ in design and in the material that they are made of. To make sure you get the right one, you should consider the way that you drive and whether you're going to take your car to the track or not.
If you're just looking to stay on the road and simply want a replacement for the stock rotor that came with your car, then a plain cast iron disc should do. It will do the job with no fuss and no drama.
However, if you plan to take your car to the track or if you want superior braking performance, we recommend that you look at cross-drilled and slotted brake discs.
Cross-drilled rotors have holes drilled right through them. The main purpose of the holes is to help dissipate the heat generated by the friction between the rotor and the brake pads.
Slotted rotors have long, shallow channels machined on their surfaces but not all the way through. Aside from heat dissipation, the slots also help keep your brake pads clean. Some discs are both cross-drilled and slotted.
If cost is not an issue, you could go for discs made using carbon ceramic composites. Unlike iron rotors, these discs are less prone to fading even under intense use.
What to look for in a brake disc
Rotors come in a variety of sizes, so make sure to get one that will perfectly fit your car. You should also get one that comes with a complete installation manual. Installing your new rotor by yourself will require some effort, but it will save you a pretty significant amount of money.
Finally, choose only products from established and trusted brands. That way, you'll be assured of excellent quality, performance, and durability.
