Your Audi vehicle's braking system is composed of several different parts, each of which plays an important role in slowing your wheels when and where you need to. Your brake calipers rank among the most essential of these parts.
How Brake Calipers Work
On your part, braking is a simple act. You press the sole of your foot against the brake pedal, and your vehicle slows. Press hard enough, or long enough, and you come to a complete stop. Behind that pedal, though, there's a lot going on.
Your pressure tells the master brake cylinder to send hydraulic brake fluid to the calipers. The force of that fluid causes the brake calipers to clamp down onto the brake rotors and generate the friction, or resistance, needed to slow the rotation of the wheels. The brake calipers have brake pads covering them to prevent the damage that metal-on-metal contact could cause.
How to Spot Failing Brake Calipers
The braking process creates a lot of heat, though. That can eventually damage any of the parts. For instance, if the brake rotors don't disperse the heat properly, the seals on your calipers can begin to decay. That leads to contaminants collecting and corroding the calipers. Signs of brake caliper failure include:
- You notice squealing or grinding sounds when you brake
- The brake pedal feels unusually soft or squishy
- You need to pump the brake pedal several times to get the brakes to engage
- Your Audi pulls to one side when you brake
- The ABS or brake system dashboard warning light comes on
If you're experience any of these symptoms, conduct an inspection of your entire braking system. If your calipers are at fault, you'll want to replace them as soon as possible to ensure safe driving.
