What Brake Calipers are & What They Do

Ever repaired or upgraded Audi brakes before? You've probably fixed if not replaced your brake calipers, then. They're what clamp your brake pads and brake rotors together during braking. The friction this causes slows and stops your vehicle.

How a brake caliper works, then, is actually pretty simple. For you, it's as easy as pressing your brake pedal. Your brake cylinder then pushes brake fluid through hoses and valves. The liquid pressurizes your brake pistons, and they charge the calipers so they can do the clamping.

The process creates serious heat, though, and it can negatively affect brake calipers eventually. For example, it can decay their seals, allowing contaminants to accumulate and often causing rust. Luckily, brake caliper problems are fairly easy to spot. Watch out for the following symptoms.

Signs of Bad Brake Calipers

  • Your brake or ABS system warning lights are lit on the dash
  • Your brakes aren't pressurizing properly; for instance, you're having to pump your brakes to slow down or stop
  • Your brake fluid's leaking, either into your engine compartment or your wheel area
  • Your Audi is pulling sideways when you brake
  • You can hear continuous grinding or squealing noises

Seeing any? You may have to change a brake caliper or two. Luckily, you can order new ones online. Better yet, you can get them from Audi directly, via our auto parts store. We've got what you need in stock, and we carry only genuine OEM, too, meaning your brake calipers will fit the car or SUV you're driving, guaranteed. So, cross another project off your maintenance checklist and buy now!
