Key Features & Benefits

This part, sometimes called a caliper bracket, basically does two main things. First, it's the mounting point for your brake caliper – that’s the part that squeezes the brake pads against the rotor. It holds the caliper securely in place. Second, it provides structural support for the whole braking system on that wheel. Think of it as the foundation. It’s a critical piece of your vehicle’s braking system, obviously. It’s directly connected to the wheel hub and suspension components. It’s what allows you to stop safely. It’s part of the unsprung weight, meaning it moves with the wheel and impacts how the suspension responds to bumps.

Symptoms, Risks & Replacements

This isn’t something you want to mess around with. If this part fails, your brakes won’t work properly, and that's a serious safety issue. It acts like a shield protecting other expensive brake components. It's made to withstand a lot of heat and stress. You’ll notice if one is damaged usually – you might feel vibrations when braking, hear noises, or experience pulling to one side. Sometimes it's obvious from visual inspection too, like rust or cracks. A lot of people find what they need at places like Fixparts Online if you’re looking to replace one yourself, but if you’re not comfortable doing brake work, definitely have a professional handle it. It’s just not worth the risk.
