These guys basically squeeze the brake pads against the rotors – those are the shiny discs you see when you look at your wheels. The caliper does this using hydraulic pressure from your brake pedal. Inside the caliper, there’s a piston, and when you hit the brakes, fluid pushes that piston out, clamping the pads onto the rotor. That’s what actually slows and stops the car. They also include the hardware to hold the pads in place and allow them to move freely. They’re a key part of your braking system, obviously. Each wheel has its own caliper. When you step on the brake, the master cylinder sends hydraulic pressure to all of them at the same time, giving you consistent stopping power. They work with the rotors and pads – it's a team effort. Without functioning calipers, you won't be able to reliably slow down or stop, pretty straightforward. Well, your safety, for starters! They're a crucial component. If a caliper fails, you’ll notice if you're pulling to one side when you brake, or it might take much longer to stop. Sometimes you'll hear a grinding noise – that usually means the pad has worn down to nothing and the caliper is contacting the rotor directly. A stuck or seized caliper can even cause the brakes to drag, overheating everything and damaging other parts. It’s something you really don’t want to mess around with. If you’re starting to see any of those signs, it’s best to get them checked out right away.
